|style="vertical-align:top" |Below are several ways of configuring the kernel psmouse driver for controlling extended TrackPoint features.
|}

= Configuration using Gnome=
If you are using GNOME, you might want to use [http://tpctl.sourceforge.net/configure-trackpoint.html configure-trackpoint] as a graphical frontend. ''([http://my.opera.com/thibi/blog/thinkpad-trackpoint-configuration-under-linux Debian/Ubuntu configuration tutorial.])''

= Configuration using DevKit =
Most recent distributions like Ubuntu 9.10 switch from HAL (being deprecated) to DevKit. Hence, the HAL configurations explained underneath, fail to work.

The easiest way to configure your touchpad and trackpoint with DevKit is by using the [http://live.gnome.org/GPointingDeviceSettings GPointingDeviceSettings] panel that fully supports the hardware. You can easily download the panel by installing {{cmduser| gpointing-device-settings}} through e.g. {{cmduser| apt-get}} on Ubuntu.

Launch the UI through the {{cmduser| gpointing-device-settings}} command, but you can also add a menu entry to your System / Preferences menu for easier access to the UI panel.

= Configuration using udev and HAL =
Modern distributions like Ubuntu 8.10 and Fedora 10 use udev and HAL to configure the input devices. You should no longer make changes to xorg.conf as by default Xorg (through the evdev driver) will let the kernel now handle input devices.

But before you get started on this you should make sure you have all the updates applied from your distro vendor as both Ubuntu 8.10 and Fedora 10 require some additional fixes that you will need.

=== Scrolling ===
By default the middle mouse button is that, a middle mouse button, which in Linux is used for the Paste operation.

But you can configure it to act in the same way as in Windows, such that you can use it for vertical scrolling (keep the button pressed and move the TrackPoint up and down to scroll). To accomplish this create the file {{path|/etc/hal/fdi/policy/mouse-wheel.fdi}} as root with the following content:

<pre>
<match key="info.product" string="TPPS/2 IBM TrackPoint">
<merge key="input.x11_options.EmulateWheel" type="string">true</merge>
<merge key="input.x11_options.EmulateWheelButton" type="string">2</merge>
<merge key="input.x11_options.YAxisMapping" type="string">4 5</merge>
<merge key="input.x11_options.Emulate3Buttons" type="string">true</merge>
<merge key="input.x11_options.EmulateWheelTimeout" type="string">200</merge>
</match>
</pre>

If you also want to have horizontal scrolling, simply add the following XAxisMapping option to the above
<pre>
<merge key="input.x11_options.XAxisMapping" type="string">6 7</merge>
</pre>
After this reboot, or restart the hal service and Xorg. You can validate the settings with {{cmd|lshal|}}.

In some models (eg: X301) you may have to use "PS/2 Generic Mouse" instead of "TPPS/2 IBM TrackPoint". Have a look to your input devices typing <code>lshal|grep input.product</code>.

====Reactivate Scrolling after suspend/resume====
Scrolling may be disabled after a resume from suspend.

You can manually reactivate the trackpoint by reloading the {{path|psmouse}} module as root:
:{{cmdroot|rmmod psmouse && modprobe psmouse}}

You can automatically force the pm-utils to reload this module.
Create a file {{path|/etc/pm/config.d/01reload_mouse}} as root with the following content:
<pre>
# reload psmouse to reactivate trackpoint scrolling
SUSPEND_MODULES="${SUSPEND_MODULES:+$SUSPEND_MODULES }psmouse"
</pre>

===Configuring other options (e.g. Press to select, Sensitivity and Speed)===

Create a file {{path|/etc/udev/rules.d/10-trackpoint.rules}} and add a line to suit your needs

<pre>
SUBSYSTEM=="serio", DRIVERS=="psmouse", ATTR{press_to_select}="1", ATTR{sensitivity}="122"
</pre>

Testing udev with {{cmdroot|udevadm test /sys/devices/platform/i8042/serio1}} should apply the new changes. All of the settings listed [[How to configure the TrackPoint#Sysfs_Options_Reference|below]] can be specified here as part of a comma separated list.

=Configuration using xinput=
If you want to modify changes on the fly, you can do so with {{cmd|xinput|}} (part of the optional xorg-x11-apps rpm on Fedora).
Note that these changes are not saved when the xserver is restarted.

To query the available options
xinput list-props "TPPS/2 IBM TrackPoint"

More information can be found in the man-pages for evdev
man evdev

To enable vertical scrolling
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation" 8 1
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Button" 8 2
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Timeout" 16 200

To enable middle button emulation (using left- and right-click simultaneously)
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Middle Button Emulation" 8 1
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Middle Button Timeout" 16 50

{{Todo|some other examples}}

=Configuration using sysfs=
Another way to modify changes on the fly, is echoing values directly into special files in sysfs.

{{NOTE|
The examples shown below are valid for ThinkPads with both TrackPoint and Touchpad, in which case the sysfs path is {{path|/sys/devices/platform/i8042/serio1/serio2}}.

If however you have a ThinkPad without Touchpad, or with the Touchpad disabled in the BIOS, the sysfs path needs to be changed to {{path|/sys/devices/platform/i8042/serio1}} instead (notice the missing serio2 at the end).}}

If you want to set the sysfs parameters at boot, you can use the [http://linux-diag.sourceforge.net/Sysfsutils.html sysfsutils] and put the preferred value in /etc/sysfs.conf.

===Press to Select===
Press to Select allows you to tap the control stick which will simulate a left click. You can enable this feature by typing the following in to a terminal (you may need to be root):

:{{cmdroot|echo -n 1 > /sys/devices/platform/i8042/serio1/serio2/press_to_select}}

Press to Select should now be enabled. You can disable it in a similar manner:

:{{cmdroot|echo -n 0 > /sys/devices/platform/i8042/serio1/serio2/press_to_select}}

You can use this script to automate the operation

#!/bin/bash
if [ "$1" = "1" ]; then
echo "Turning on tap on TrackPoint"
echo -n 1 > /sys/devices/platform/i8042/serio1/serio2/press_to_select
exit 0
fi
if [ "$1" = "0" ]; then
echo "Turning off tap on TrackPoint"
echo -n 0 > /sys/devices/platform/i8042/serio1/serio2/press_to_select
exit 0
fi
echo -n "Tap status: "
cat /sys/devices/platform/i8042/serio1/serio2/press_to_select

In Ubuntu 8.10 to make Press to Select a permanent change:

echo -n 1 | tee /sys/devices/platform/i8042/serio1/serio2/press_to_select

As root, append the above command above "exit 0" in /etc/gdm/Init/Default

===Sensitivity & Speed===
Adjusting the speed and sensitivity of the TrackPoint requires echoing a value between 0 and 255 into the appropriate file. For example, for a speed of 120 and a sensitivity of 250, type the following into a terminal:

:{{cmdroot|echo -n 120 > /sys/devices/platform/i8042/serio1/serio2/speed}}
:{{cmdroot|echo -n 250 > /sys/devices/platform/i8042/serio1/serio2/sensitivity}}

Feel free to experiment with your settings until you find a combination that is comfortable.

When you satisfy your setting, add the two lines into /etc/rc.d/rc.local in order to avoid restoring the default setting every time the system reboots. In Ubuntu 9.10, add the lines to /etc/rc.local to avoid this.

===Vertical Scrolling===
No sysfs entry exists for vertical scrolling in kernels after 2.6.11.

The feature was removed as it was not a hardware feature, but rather emulating a scroll action in software and as such did not belong in the kernel.
Instead the scroll feature of the Xserver should be used, which can be activated with HAL or xinput as described above.

=Configuration using the X server (old Xorg only)=
{{NOTE|This only applies to old distributions with Xorg versions that did not yet use evdev. For modern distributions use one of the other methods}}
The scroll setting has been removed from the trackpoint driver in kernel versions 2.6.11 and above. Scroll emulation should now be handled in the X server.

A nice side effect of that is, that middle button scrolling applies to any mouse and not just the TrackPoint interface, which can be a quite handy feature for desktop computers or people who prefer to use an external mouse, especially when scrolling through long lists or needing to use horizontal scrolling with a mouse which has only a vertical scroll wheel.

The necessary functionality, known as "EmulateWheelTimeout" allowing to use button 2 for a middle click, wasn't implemented in Xorg prior to 6.9/7.0. However, there was a patch included in most distributions packages of Xorg, which was announced [http://www.mail-archive.com/devel@xfree86.org/msg03333.html here]. You can find an updated version of the package in the experimental branch of {{Debian}} or try to build the mouse driver yourself with the information in the announcement. This has successfully been tried with FC3's 6.8.2 packages.

Once this functionality is in the X.org, add these lines to your TrackPoint configuration section in {{path|/etc/X11/xorg.conf}}:

Option "EmulateWheel" "on"
Option "EmulateWheelButton" "2"

It may also be necessary to add these lines:

Option "YAxisMapping" "4 5"
Option "XAxisMapping" "6 7"

which specify which buttons are mapped to motion in the vertical (Y) and horizontal (X) directions, respectively, in wheel emulation mode (see http://www.xfree86.org/current/mouse.4.html).

{{HINT| Use the program "xev" to see, what mouse button identifiers are sent by your mouse/touchpad/trackpoint.<br />You might want to try: "xev | grep button"}}
{{HINT| If it does not work see if evdev is installed and remove it. On gentoo do the following:<br />
eix xf86-input-evdev<br />
emerge -C xf86-input-evdev<br />
and then remove the evdev flag in make.conf INPUT_DEVICES}}

So, a complete mouse section, that implements this nicely and works very well on my R51, even with a simultaneously connected USB mouse, looks like that (tried out today, 20th of September, 2006 on Dapper):

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPS/2"
Option "Emulate3Buttons" "on"
Option "Emulate3TimeOut" "50"
Option "EmulateWheel" "on"
Option "EmulateWheelTimeOut" "200"
Option "EmulateWheelButton" "2"
Option "YAxisMapping" "4 5"
Option "XAxisMapping" "6 7"
Option "ZAxisMapping" "4 5"
EndSection

The mappings for Y and Z are the same, since the "Z-Axis" refers to actual hardware scrolling wheels which usually scroll the screen along the Y-Axis. If there is no hardware scrolling wheel present, horizontal and vertical scrolling using the TrackPoint work fine without the Z-Axis line.

Now restart X and hold down button 2 and move the mouse to scroll, or just press and release button 2 for a middle click.

To make this work with the synaptics driver for the touchpad, you can add
Option "GuestMouseOff" "1"
to the synaptics device section. This will make the synaptics driver ignore the Trackpoint, so it will be handled by the mouse driver. This allowed me to disable the touchpad while making the TrackPoint work like it should.

{{NOTE| With the above mouse section in my xorg.conf all this works like a charm:
*I can press the wheel on my external USB mouse and move the mouse up and down for scrolling
*or I can just use the wheel on the external mouse for scrolling
*or pressing the MMB button of the trackpoint and use the trackpoint for scrolling.
*Even horizontal scrolling works automagically in Konqueror, for Firefox/Opera see below.

Simultaneously I can use
*a press on the external mouse's wheel
*or the MMB of the trackpoint

for pasting the buffer. Lovely! :) }}

{{HINT| If you don't use the middle-mouse-button for pasting and sometimes pasting things by mistake while scrolling (witch is really odd) simply set the "EmulateWheelTimeOut" to "1" as a (bloody) workaround. Middle click will only possible with pressing left and right button simultaneously!}}
=Application specific tweaks=
===Configure Opera for using trackpoint horizontal scrolling===
To fix horizontal scrolling in Opera, you need to edit the configfile <tt>standard_mouse.ini</tt> in e.g. /usr/share/opera/ini/ (Debian) or /opt/opera/share/opera/ini/ (Gentoo) and comment out the following lines
<pre>
Button6 = Back
Button7 = Forward
</pre>
so they look like that
<pre>
;Button6 = Back
;Button7 = Forward
</pre>
Remember, Button6 and Button7 do not so coincidental correspond with our X configuration we know from above:
<pre>
Option "YAxisMapping" "6 7"
</pre>
After this change you will be able to scroll vertically and horizontally with your middle button.

===Firefox 3 tweaks===
These settings make Firefox on Linux behave more like the Windows version. They were tested on an out of the box Fedora 10 system on a Thinkpad T61. Go into about:config, and set the following:

middlemouse.paste = false
middlemouse.contentLoadURL = false
general.autoScroll = true

Problem with unauthorized MiniPCI network card

2008-07-24T04:34:42Z

Mini g: /* Successful BIOS Modifications */

==Problem Description==
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS. IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.

==Affected Models==
All machines with integrated WiFi, or machines with WiFi added

==Affected Operating Systems==
All - problem is in the BIOS

==Status==
* Workarounds exist for most affected models.

==Solutions==
It may be possible to use the computer with the unauthorized card deactivated (but not removed). Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled. This does not make the wireless card work, but it may allow you to boot the computer normally.

{{NOTE|Any of the following solutions should suffice to make the wireless card useable. You only need to perform one of them.}}

* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use. The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}

* A safer and better method than modifying the BIOS is modifying the PCI-ID of the wlan card to match the authorized one(why? 1.you'll risk the wireless card instead of the motherbord 2.future BIOS updates will not create any problem 3.no problem with newer laptops with different BIOS, the only reqirement is to find an ID that is already listed in the BIOS that can be easily acheived if community maintain a compatibility table). The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here]. This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards. Instruction for intel 2200/2915 cards are [http://stachon.webpark.cz/ipw-eeprom.html here].
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop. Also, this procedure can render your card useless, but that's better than bricking your laptop.}}

* Another safer method: You can plug the wireless card into the spare WWAN slot (the second miniPCI slot) with pin-20 taped over. It has been tested on a Thinkpad X61s and a non-IBM (unauthorized) Intel Wifi link 4965agn card, originally it gave a 1802 error, but using this trick it boots up and works without any apparent problem-- it essentially hides the card from the test in the bios, but the WWAN slot still gives the card access to the proper PCI bus, with no need to modify the computer or card.

* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.

* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43 and X41

* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}

<code>
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <sys/stat.h>
#include <fcntl.h>

int main(void)
{
int fd;
unsigned char data;

fd = open("/dev/nvram", O_RDWR);
if (fd==-1) {
printf("Opening /dev/nvram failed\n");
return 1;
}
printf("Disabling WiFi whitelist check.\n");

/* BIG INFORMATIONAL WARNING */
/* The linux nvram driver doesn't give access to the first 14 bytes of
the CMOS. As a result, we seek to 0x5c rather than 0x6a. If you're
implementing this under another OS, then you'll have to go to whichever
address is appropriate for your access method */

lseek(fd, 0x5c, SEEK_SET);
read(fd, &data, 1);
printf("CMOS address 0x5c: %02x->", data);
data |= 0x80;
printf("%02x\n", data);
lseek(fd, 0x5c, SEEK_SET);
if (write(fd, &data, 1)<0) {
printf("Unable to write to /dev/nvram - hack failed\n");
close(fd);
return 2;
}
close(fd);
printf("Done.\n");
return 0;
}

</code>
{{NOTE|On the R32, T43, X41, X60 and probably others, the BIOS hacks and the "no-1802" utility don't work.}}

==Problem with WiFi LED==
After getting an unauthorized card to work, you may notice that the WiFi LED found on the ThinkPad is not working. This doesn't happen with all unauthorized cards. The general cause for this is the fact that the MiniPCI standard leaves the implementation of the LED signals available on the MiniPCI connector to the card vendors. Therefore some newer WiFi cards use one of the signals originally meant for LEDs to implement the "radio kill" switch input. As a result, the LED doesn't get proper signals and fails.

====Details====
The WiFi LED found in ThinkPads is connected to following pins on the MiniPCI connector.

|LED1_GRNN
|WiFi active LED - (older cards) / RF Silent input (newer cards)
|}
Note: The descriptions are specific to this article.

If your LED is not working, the problem could be the pin 13. Newer cards may no longer provide the necessary negative signal there to drive the LED. Before you apply any fixes, be sure to check the voltage between pin 11 and ground (can be found for example on the MiniPCI latch arms) - it should give you about 3.3V while the WiFi is active and 0V otherwise. The voltage between pin 13 and ground should measure about 2.5V. The notebook has to be running while you perform the tests so be extremely careful. All the mentioned pins are on the upper side so it's quite easy to get to them with a multimeter. If all the voltages match, your LED is fixable.

====Solution====
The solution is to connect the ground (GND) to the pin 13. However, since the new ''RF Silent input'' signal is active low, grounding the card side will tell it to turn itself off. Therefore, we have to separate pin 13 of the card from the system board and connect ground to the system board side only.

There are many ways to accomplish this. One which doesn't require any soldering is to mask pin 13 on the card with a cellophane tape and use about 3cm of thin wire to connect pin 13 of the connector to the ground. Place one end of the wire on the masked pad and insert the card into the slot. Check if the wire is centered on the pad and try pulling it (but not too hard) to see if it holds. If it comes out easily, pull the card out and repeat. If you successfully attach it, you have to connect the other end to the ground. The best place is the left MiniPCI latch arm. Bend it outside and insert the wire into the small gap between the two pieces of metal the arm is made from. Finally, make sure that the wire doesn't touch anything else and doesn't stand out too much, it must not touch the touchpad electronics when you put the palmrest back on. If in doubt, cover the wire with some insulator.

{{WARN|Do this fix ONLY if you know exactly what you are doing and at your own risk! If you're not sure about any part, don't even try it or you may damage your WiFi card and/or brick your laptop. You have been warned.}}

{{NOTE|If your card is not listed in the table below, your WiFi LED may not work for some other reason. Therefore, make sure you understood the problem described here and made all the measurements carefully. This way you will know if this apply to your card and if it can be fixed this way. Otherwise, if you're skilled enough, please try to find out why your LED doesn't work and contribute to this article.}}

Problem with unauthorized MiniPCI network card

2008-07-20T22:14:59Z

Mini g: /* Successful BIOS Modifications */

==Problem Description==
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS. IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.

==Affected Models==
All machines with integrated WiFi, or machines with WiFi added

==Affected Operating Systems==
All - problem is in the BIOS

==Status==
* Workarounds exist for most affected models.

==Solutions==
It may be possible to use the computer with the unauthorized card deactivated (but not removed). Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled. This does not make the wireless card work, but it may allow you to boot the computer normally.

{{NOTE|Any of the following solutions should suffice to make the wireless card useable. You only need to perform one of them.}}

* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use. The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}

* A safer and better method than modifying the BIOS is modifying the PCI-ID of the wlan card to match the authorized one(why? 1.you'll risk the wireless card instead of the motherbord 2.future BIOS updates will not create any problem 3.no problem with newer laptops with different BIOS, the only reqirement is to find an ID that is already listed in the BIOS that can be easily acheived if community maintain a compatibility table). The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here]. This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards. Instruction for intel 2200/2915 cards are [http://stachon.webpark.cz/ipw-eeprom.html here].
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop. Also, this procedure can render your card useless, but that's better than bricking your laptop.}}

* Another safer method: You can plug the wireless card into the spare WWAN slot (the second miniPCI slot) with pin-20 taped over. It has been tested on a Thinkpad X61s and a non-IBM (unauthorized) Intel Wifi link 4965agn card, originally it gave a 1802 error, but using this trick it boots up and works without any apparent problem-- it essentially hides the card from the test in the bios, but the WWAN slot still gives the card access to the proper PCI bus, with no need to modify the computer or card.

* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.

* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43 and X41

* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}

<code>
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <sys/stat.h>
#include <fcntl.h>

int main(void)
{
int fd;
unsigned char data;

fd = open("/dev/nvram", O_RDWR);
if (fd==-1) {
printf("Opening /dev/nvram failed\n");
return 1;
}
printf("Disabling WiFi whitelist check.\n");

/* BIG INFORMATIONAL WARNING */
/* The linux nvram driver doesn't give access to the first 14 bytes of
the CMOS. As a result, we seek to 0x5c rather than 0x6a. If you're
implementing this under another OS, then you'll have to go to whichever
address is appropriate for your access method */

lseek(fd, 0x5c, SEEK_SET);
read(fd, &data, 1);
printf("CMOS address 0x5c: %02x->", data);
data |= 0x80;
printf("%02x\n", data);
lseek(fd, 0x5c, SEEK_SET);
if (write(fd, &data, 1)<0) {
printf("Unable to write to /dev/nvram - hack failed\n");
close(fd);
return 2;
}
close(fd);
printf("Done.\n");
return 0;
}

==Problem with WiFi LED==
After getting an unauthorized card to work, you may notice that the WiFi LED found on the ThinkPad is not working. This doesn't happen with all unauthorized cards. The general cause for this is the fact that the MiniPCI standard leaves the implementation of the LED signals available on the MiniPCI connector to the card vendors. Therefore some newer WiFi cards use one of the signals originally meant for LEDs to implement the "radio kill" switch input. As a result, the LED doesn't get proper signals and fails.

====Details====
The WiFi LED found in ThinkPads is connected to following pins on the MiniPCI connector.

|LED1_GRNN
|WiFi active LED - (older cards) / RF Silent input (newer cards)
|}
Note: The descriptions are specific to this article.

If your LED is not working, the problem could be the pin 13. Newer cards may no longer provide the necessary negative signal there to drive the LED. Before you apply any fixes, be sure to check the voltage between pin 11 and ground (can be found for example on the MiniPCI latch arms) - it should give you about 3.3V while the WiFi is active and 0V otherwise. The voltage between pin 13 and ground should measure about 2.5V. The notebook has to be running while you perform the tests so be extremely careful. All the mentioned pins are on the upper side so it's quite easy to get to them with a multimeter. If all the voltages match, your LED is fixable.

[http://www.interfacebus.com/MiniPCI_Pinout_124Pin.html MiniPCI Pinout]

====Solution====
The solution is to connect the ground (GND) to the pin 13. However, since the new ''RF Silent input'' signal is active low, grounding the card side will tell it to turn itself off. Therefore, we have to separate pin 13 of the card from the system board and connect ground to the system board side only.

There are many ways to accomplish this. One which doesn't require any soldering is to mask pin 13 on the card with a cellophane tape and use about 3cm of thin wire to connect pin 13 of the connector to the ground. Place one end of the wire on the masked pad and insert the card into the slot. Check if the wire is centered on the pad and try pulling it (but not too hard) to see if it holds. If it comes out easily, pull the card out and repeat. If you successfully attach it, you have to connect the other end to the ground. The best place is the left MiniPCI latch arm. Bend it outside and insert the wire into the small gap between the two pieces of metal the arm is made from. Finally, make sure that the wire doesn't touch anything else and doesn't stand out too much, it must not touch the touchpad electronics when you put the palmrest back on. If in doubt, cover the wire with some insulator.

{{WARN|Do this fix ONLY if you know exactly what you are doing and at your own risk! If you're not sure about any part, don't even try it or you may damage your WiFi card and/or brick your laptop. You have been warned.}}

{{NOTE|If your card is not listed in the table below, your WiFi LED may not work for some other reason. Therefore, make sure you understood the problem described here and made all the measurements carefully. This way you will know if this apply to your card and if it can be fixed this way. Otherwise, if you're skilled enough, please try to find out why your LED doesn't work and contribute to this article.}}

Problem with unauthorized MiniPCI network card

2008-07-20T22:14:11Z

Mini g: /* Successful BIOS Modifications */

==Problem Description==
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS. IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.

==Affected Models==
All machines with integrated WiFi, or machines with WiFi added

==Affected Operating Systems==
All - problem is in the BIOS

==Status==
* Workarounds exist for most affected models.

==Solutions==
It may be possible to use the computer with the unauthorized card deactivated (but not removed). Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled. This does not make the wireless card work, but it may allow you to boot the computer normally.

{{NOTE|Any of the following solutions should suffice to make the wireless card useable. You only need to perform one of them.}}

* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use. The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}

* A safer and better method than modifying the BIOS is modifying the PCI-ID of the wlan card to match the authorized one(why? 1.you'll risk the wireless card instead of the motherbord 2.future BIOS updates will not create any problem 3.no problem with newer laptops with different BIOS, the only reqirement is to find an ID that is already listed in the BIOS that can be easily acheived if community maintain a compatibility table). The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here]. This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards. Instruction for intel 2200/2915 cards are [http://stachon.webpark.cz/ipw-eeprom.html here].
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop. Also, this procedure can render your card useless, but that's better than bricking your laptop.}}

* Another safer method: You can plug the wireless card into the spare WWAN slot (the second miniPCI slot) with pin-20 taped over. It has been tested on a Thinkpad X61s and a non-IBM (unauthorized) Intel Wifi link 4965agn card, originally it gave a 1802 error, but using this trick it boots up and works without any apparent problem-- it essentially hides the card from the test in the bios, but the WWAN slot still gives the card access to the proper PCI bus, with no need to modify the computer or card.

* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.

* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43 and X41

* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}

<code>
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <sys/stat.h>
#include <fcntl.h>

int main(void)
{
int fd;
unsigned char data;

fd = open("/dev/nvram", O_RDWR);
if (fd==-1) {
printf("Opening /dev/nvram failed\n");
return 1;
}
printf("Disabling WiFi whitelist check.\n");

/* BIG INFORMATIONAL WARNING */
/* The linux nvram driver doesn't give access to the first 14 bytes of
the CMOS. As a result, we seek to 0x5c rather than 0x6a. If you're
implementing this under another OS, then you'll have to go to whichever
address is appropriate for your access method */

lseek(fd, 0x5c, SEEK_SET);
read(fd, &data, 1);
printf("CMOS address 0x5c: %02x->", data);
data |= 0x80;
printf("%02x\n", data);
lseek(fd, 0x5c, SEEK_SET);
if (write(fd, &data, 1)<0) {
printf("Unable to write to /dev/nvram - hack failed\n");
close(fd);
return 2;
}
close(fd);
printf("Done.\n");
return 0;
}

==Problem with WiFi LED==
After getting an unauthorized card to work, you may notice that the WiFi LED found on the ThinkPad is not working. This doesn't happen with all unauthorized cards. The general cause for this is the fact that the MiniPCI standard leaves the implementation of the LED signals available on the MiniPCI connector to the card vendors. Therefore some newer WiFi cards use one of the signals originally meant for LEDs to implement the "radio kill" switch input. As a result, the LED doesn't get proper signals and fails.

====Details====
The WiFi LED found in ThinkPads is connected to following pins on the MiniPCI connector.

|WiFi active LED - (older cards) / RF Silent input (newer cards)
|}
Note: The descriptions are specific to this article.

If your LED is not working, the problem could be the pin 13. Newer cards may no longer provide the necessary negative signal there to drive the LED. Before you apply any fixes, be sure to check the voltage between pin 11 and ground (can be found for example on the MiniPCI latch arms) - it should give you about 3.3V while the WiFi is active and 0V otherwise. The voltage between pin 13 and ground should measure about 2.5V. The notebook has to be running while you perform the tests so be extremely careful. All the mentioned pins are on the upper side so it's quite easy to get to them with a multimeter. If all the voltages match, your LED is fixable.

[http://www.interfacebus.com/MiniPCI_Pinout_124Pin.html MiniPCI Pinout]

====Solution====
The solution is to connect the ground (GND) to the pin 13. However, since the new ''RF Silent input'' signal is active low, grounding the card side will tell it to turn itself off. Therefore, we have to separate pin 13 of the card from the system board and connect ground to the system board side only.

There are many ways to accomplish this. One which doesn't require any soldering is to mask pin 13 on the card with a cellophane tape and use about 3cm of thin wire to connect pin 13 of the connector to the ground. Place one end of the wire on the masked pad and insert the card into the slot. Check if the wire is centered on the pad and try pulling it (but not too hard) to see if it holds. If it comes out easily, pull the card out and repeat. If you successfully attach it, you have to connect the other end to the ground. The best place is the left MiniPCI latch arm. Bend it outside and insert the wire into the small gap between the two pieces of metal the arm is made from. Finally, make sure that the wire doesn't touch anything else and doesn't stand out too much, it must not touch the touchpad electronics when you put the palmrest back on. If in doubt, cover the wire with some insulator.

{{WARN|Do this fix ONLY if you know exactly what you are doing and at your own risk! If you're not sure about any part, don't even try it or you may damage your WiFi card and/or brick your laptop. You have been warned.}}

{{NOTE|If your card is not listed in the table below, your WiFi LED may not work for some other reason. Therefore, make sure you understood the problem described here and made all the measurements carefully. This way you will know if this apply to your card and if it can be fixed this way. Otherwise, if you're skilled enough, please try to find out why your LED doesn't work and contribute to this article.}}

Problem with unauthorized MiniPCI network card

2008-07-20T22:12:40Z

Mini g: /* Successful BIOS Modifications */

==Problem Description==
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS. IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.

==Affected Models==
All machines with integrated WiFi, or machines with WiFi added

==Affected Operating Systems==
All - problem is in the BIOS

==Status==
* Workarounds exist for most affected models.

==Solutions==
It may be possible to use the computer with the unauthorized card deactivated (but not removed). Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled. This does not make the wireless card work, but it may allow you to boot the computer normally.

{{NOTE|Any of the following solutions should suffice to make the wireless card useable. You only need to perform one of them.}}

* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use. The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}

* A safer and better method than modifying the BIOS is modifying the PCI-ID of the wlan card to match the authorized one(why? 1.you'll risk the wireless card instead of the motherbord 2.future BIOS updates will not create any problem 3.no problem with newer laptops with different BIOS, the only reqirement is to find an ID that is already listed in the BIOS that can be easily acheived if community maintain a compatibility table). The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here]. This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards. Instruction for intel 2200/2915 cards are [http://stachon.webpark.cz/ipw-eeprom.html here].
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop. Also, this procedure can render your card useless, but that's better than bricking your laptop.}}

* Another safer method: You can plug the wireless card into the spare WWAN slot (the second miniPCI slot) with pin-20 taped over. It has been tested on a Thinkpad X61s and a non-IBM (unauthorized) Intel Wifi link 4965agn card, originally it gave a 1802 error, but using this trick it boots up and works without any apparent problem-- it essentially hides the card from the test in the bios, but the WWAN slot still gives the card access to the proper PCI bus, with no need to modify the computer or card.

* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.

* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43 and X41

* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}

==Problem with WiFi LED==
After getting an unauthorized card to work, you may notice that the WiFi LED found on the ThinkPad is not working. This doesn't happen with all unauthorized cards. The general cause for this is the fact that the MiniPCI standard leaves the implementation of the LED signals available on the MiniPCI connector to the card vendors. Therefore some newer WiFi cards use one of the signals originally meant for LEDs to implement the "radio kill" switch input. As a result, the LED doesn't get proper signals and fails.

The WiFi LED found in ThinkPads is connected to following pins on the MiniPCI connector.

Note: The descriptions are specific to this article.

If your LED is not working, the problem could be the pin 13. Newer cards may no longer provide the necessary negative signal there to drive the LED. Before you apply any fixes, be sure to check the voltage between pin 11 and ground (can be found for example on the MiniPCI latch arms) - it should give you about 3.3V while the WiFi is active and 0V otherwise. The voltage between pin 13 and ground should measure about 2.5V. The notebook has to be running while you perform the tests so be extremely careful. All the mentioned pins are on the upper side so it's quite easy to get to them with a multimeter. If all the voltages match, your LED is fixable.

====Solution====
The solution is to connect the ground (GND) to the pin 13. However, since the new ''RF Silent input'' signal is active low, grounding the card side will tell it to turn itself off. Therefore, we have to separate pin 13 of the card from the system board and connect ground to the system board side only.

There are many ways to accomplish this. One which doesn't require any soldering is to mask pin 13 on the card with a cellophane tape and use about 3cm of thin wire to connect pin 13 of the connector to the ground. Place one end of the wire on the masked pad and insert the card into the slot. Check if the wire is centered on the pad and try pulling it (but not too hard) to see if it holds. If it comes out easily, pull the card out and repeat. If you successfully attach it, you have to connect the other end to the ground. The best place is the left MiniPCI latch arm. Bend it outside and insert the wire into the small gap between the two pieces of metal the arm is made from. Finally, make sure that the wire doesn't touch anything else and doesn't stand out too much, it must not touch the touchpad electronics when you put the palmrest back on. If in doubt, cover the wire with some insulator.

{{WARN|Do this fix ONLY if you know exactly what you are doing and at your own risk! If you're not sure about any part, don't even try it or you may damage your WiFi card and/or brick your laptop. You have been warned.}}

{{NOTE|If your card is not listed in the table below, your WiFi LED may not work for some other reason. Therefore, make sure you understood the problem described here and made all the measurements carefully. This way you will know if this apply to your card and if it can be fixed this way. Otherwise, if you're skilled enough, please try to find out why your LED doesn't work and contribute to this article.}}

Problem with unauthorized MiniPCI network card

2008-07-20T22:12:15Z

Mini g: /* Successful BIOS Modifications */

==Problem Description==
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS. IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.

==Affected Models==
All machines with integrated WiFi, or machines with WiFi added

==Affected Operating Systems==
All - problem is in the BIOS

==Status==
* Workarounds exist for most affected models.

==Solutions==
It may be possible to use the computer with the unauthorized card deactivated (but not removed). Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled. This does not make the wireless card work, but it may allow you to boot the computer normally.

{{NOTE|Any of the following solutions should suffice to make the wireless card useable. You only need to perform one of them.}}

* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use. The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}

* A safer and better method than modifying the BIOS is modifying the PCI-ID of the wlan card to match the authorized one(why? 1.you'll risk the wireless card instead of the motherbord 2.future BIOS updates will not create any problem 3.no problem with newer laptops with different BIOS, the only reqirement is to find an ID that is already listed in the BIOS that can be easily acheived if community maintain a compatibility table). The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here]. This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards. Instruction for intel 2200/2915 cards are [http://stachon.webpark.cz/ipw-eeprom.html here].
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop. Also, this procedure can render your card useless, but that's better than bricking your laptop.}}

* Another safer method: You can plug the wireless card into the spare WWAN slot (the second miniPCI slot) with pin-20 taped over. It has been tested on a Thinkpad X61s and a non-IBM (unauthorized) Intel Wifi link 4965agn card, originally it gave a 1802 error, but using this trick it boots up and works without any apparent problem-- it essentially hides the card from the test in the bios, but the WWAN slot still gives the card access to the proper PCI bus, with no need to modify the computer or card.

* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.

* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43 and X41

* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}

<code>
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <sys/stat.h>

{
int fd;
unsigned char data;

fd = open("/dev/nvram", O_RDWR);
if (fd==-1) {
printf("Opening /dev/nvram failed\n");
return 1;
}
printf("Disabling WiFi whitelist check.\n");

/* BIG INFORMATIONAL WARNING */
/* The linux nvram driver doesn't give access to the first 14 bytes of
the CMOS. As a result, we seek to 0x5c rather than 0x6a. If you're
implementing this under another OS, then you'll have to go to whichever
address is appropriate for your access method */

lseek(fd, 0x5c, SEEK_SET);
read(fd, &data, 1);
printf("CMOS address 0x5c: %02x->", data);
data |= 0x80;
printf("%02x\n", data);
lseek(fd, 0x5c, SEEK_SET);
if (write(fd, &data, 1)<0) {
printf("Unable to write to /dev/nvram - hack failed\n");
close(fd);
return 2;
}
close(fd);
printf("Done.\n");
return 0;
}

==Problem with WiFi LED==
After getting an unauthorized card to work, you may notice that the WiFi LED found on the ThinkPad is not working. This doesn't happen with all unauthorized cards. The general cause for this is the fact that the MiniPCI standard leaves the implementation of the LED signals available on the MiniPCI connector to the card vendors. Therefore some newer WiFi cards use one of the signals originally meant for LEDs to implement the "radio kill" switch input. As a result, the LED doesn't get proper signals and fails.

====Details====
The WiFi LED found in ThinkPads is connected to following pins on the MiniPCI connector.
{| align="center" cellpadding="2" width="100%" style="border:1px; background:grey;"

|LED1_GRNN
|WiFi active LED - (older cards) / RF Silent input (newer cards)
|}
Note: The descriptions are specific to this article.

If your LED is not working, the problem could be the pin 13. Newer cards may no longer provide the necessary negative signal there to drive the LED. Before you apply any fixes, be sure to check the voltage between pin 11 and ground (can be found for example on the MiniPCI latch arms) - it should give you about 3.3V while the WiFi is active and 0V otherwise. The voltage between pin 13 and ground should measure about 2.5V. The notebook has to be running while you perform the tests so be extremely careful. All the mentioned pins are on the upper side so it's quite easy to get to them with a multimeter. If all the voltages match, your LED is fixable.

[http://www.interfacebus.com/MiniPCI_Pinout_124Pin.html MiniPCI Pinout]

====Solution====
The solution is to connect the ground (GND) to the pin 13. However, since the new ''RF Silent input'' signal is active low, grounding the card side will tell it to turn itself off. Therefore, we have to separate pin 13 of the card from the system board and connect ground to the system board side only.

There are many ways to accomplish this. One which doesn't require any soldering is to mask pin 13 on the card with a cellophane tape and use about 3cm of thin wire to connect pin 13 of the connector to the ground. Place one end of the wire on the masked pad and insert the card into the slot. Check if the wire is centered on the pad and try pulling it (but not too hard) to see if it holds. If it comes out easily, pull the card out and repeat. If you successfully attach it, you have to connect the other end to the ground. The best place is the left MiniPCI latch arm. Bend it outside and insert the wire into the small gap between the two pieces of metal the arm is made from. Finally, make sure that the wire doesn't touch anything else and doesn't stand out too much, it must not touch the touchpad electronics when you put the palmrest back on. If in doubt, cover the wire with some insulator.

{{WARN|Do this fix ONLY if you know exactly what you are doing and at your own risk! If you're not sure about any part, don't even try it or you may damage your WiFi card and/or brick your laptop. You have been warned.}}

{{NOTE|If your card is not listed in the table below, your WiFi LED may not work for some other reason. Therefore, make sure you understood the problem described here and made all the measurements carefully. This way you will know if this apply to your card and if it can be fixed this way. Otherwise, if you're skilled enough, please try to find out why your LED doesn't work and contribute to this article.}}

Problem with unauthorized MiniPCI network card

2008-07-20T22:10:57Z

Mini g: /* Successful BIOS Modifications */

==Problem Description==
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS. IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.

==Affected Models==
All machines with integrated WiFi, or machines with WiFi added

==Affected Operating Systems==
All - problem is in the BIOS

==Status==
* Workarounds exist for most affected models.

==Solutions==
It may be possible to use the computer with the unauthorized card deactivated (but not removed). Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled. This does not make the wireless card work, but it may allow you to boot the computer normally.

{{NOTE|Any of the following solutions should suffice to make the wireless card useable. You only need to perform one of them.}}

* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use. The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}

* A safer and better method than modifying the BIOS is modifying the PCI-ID of the wlan card to match the authorized one(why? 1.you'll risk the wireless card instead of the motherbord 2.future BIOS updates will not create any problem 3.no problem with newer laptops with different BIOS, the only reqirement is to find an ID that is already listed in the BIOS that can be easily acheived if community maintain a compatibility table). The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here]. This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards. Instruction for intel 2200/2915 cards are [http://stachon.webpark.cz/ipw-eeprom.html here].
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop. Also, this procedure can render your card useless, but that's better than bricking your laptop.}}

* Another safer method: You can plug the wireless card into the spare WWAN slot (the second miniPCI slot) with pin-20 taped over. It has been tested on a Thinkpad X61s and a non-IBM (unauthorized) Intel Wifi link 4965agn card, originally it gave a 1802 error, but using this trick it boots up and works without any apparent problem-- it essentially hides the card from the test in the bios, but the WWAN slot still gives the card access to the proper PCI bus, with no need to modify the computer or card.

* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.

* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43 and X41

* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}

<code>
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <sys/stat.h>
#include <fcntl.h>

int main(void)
{
int fd;
unsigned char data;

fd = open("/dev/nvram", O_RDWR);
if (fd==-1) {
printf("Opening /dev/nvram failed\n");
return 1;
}
printf("Disabling WiFi whitelist check.\n");

/* BIG INFORMATIONAL WARNING */
/* The linux nvram driver doesn't give access to the first 14 bytes of
the CMOS. As a result, we seek to 0x5c rather than 0x6a. If you're
implementing this under another OS, then you'll have to go to whichever
address is appropriate for your access method */

lseek(fd, 0x5c, SEEK_SET);
read(fd, &data, 1);
printf("CMOS address 0x5c: %02x->", data);
data |= 0x80;
printf("%02x\n", data);
lseek(fd, 0x5c, SEEK_SET);
if (write(fd, &data, 1)<0) {
printf("Unable to write to /dev/nvram - hack failed\n");
close(fd);
return 2;
}
close(fd);
printf("Done.\n");
return 0;
}

==Problem with WiFi LED==
After getting an unauthorized card to work, you may notice that the WiFi LED found on the ThinkPad is not working. This doesn't happen with all unauthorized cards. The general cause for this is the fact that the MiniPCI standard leaves the implementation of the LED signals available on the MiniPCI connector to the card vendors. Therefore some newer WiFi cards use one of the signals originally meant for LEDs to implement the "radio kill" switch input. As a result, the LED doesn't get proper signals and fails.

====Details====
The WiFi LED found in ThinkPads is connected to following pins on the MiniPCI connector.

|LED1_GRNN
|WiFi active LED - (older cards) / RF Silent input (newer cards)
|}
Note: The descriptions are specific to this article.

If your LED is not working, the problem could be the pin 13. Newer cards may no longer provide the necessary negative signal there to drive the LED. Before you apply any fixes, be sure to check the voltage between pin 11 and ground (can be found for example on the MiniPCI latch arms) - it should give you about 3.3V while the WiFi is active and 0V otherwise. The voltage between pin 13 and ground should measure about 2.5V. The notebook has to be running while you perform the tests so be extremely careful. All the mentioned pins are on the upper side so it's quite easy to get to them with a multimeter. If all the voltages match, your LED is fixable.

[http://www.interfacebus.com/MiniPCI_Pinout_124Pin.html MiniPCI Pinout]

====Solution====
The solution is to connect the ground (GND) to the pin 13. However, since the new ''RF Silent input'' signal is active low, grounding the card side will tell it to turn itself off. Therefore, we have to separate pin 13 of the card from the system board and connect ground to the system board side only.

There are many ways to accomplish this. One which doesn't require any soldering is to mask pin 13 on the card with a cellophane tape and use about 3cm of thin wire to connect pin 13 of the connector to the ground. Place one end of the wire on the masked pad and insert the card into the slot. Check if the wire is centered on the pad and try pulling it (but not too hard) to see if it holds. If it comes out easily, pull the card out and repeat. If you successfully attach it, you have to connect the other end to the ground. The best place is the left MiniPCI latch arm. Bend it outside and insert the wire into the small gap between the two pieces of metal the arm is made from. Finally, make sure that the wire doesn't touch anything else and doesn't stand out too much, it must not touch the touchpad electronics when you put the palmrest back on. If in doubt, cover the wire with some insulator.

{{WARN|Do this fix ONLY if you know exactly what you are doing and at your own risk! If you're not sure about any part, don't even try it or you may damage your WiFi card and/or brick your laptop. You have been warned.}}

{{NOTE|If your card is not listed in the table below, your WiFi LED may not work for some other reason. Therefore, make sure you understood the problem described here and made all the measurements carefully. This way you will know if this apply to your card and if it can be fixed this way. Otherwise, if you're skilled enough, please try to find out why your LED doesn't work and contribute to this article.}}
