Problem with unauthorized MiniPCI network card

2009-01-12T15:51:09Z

Ruena:

==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] or [http://www.thinkpad-forum.de/thinkpad-hardware/zubeh%C3%B6r/44192-tutorial-nicht-ibm-wlan-karte-2200-2915-im-thinkpad/ here] (in German). The second one is much simpler because it provides an already patched and compiled ipw2200 driver required to do the job.
{{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 express 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. Other combinations reported to work with this method: Thinkpad X61 / Intel 3945abg (bulk).

* 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, W500 and probably others, the BIOS hacks and the "no-1802" utility don't work.}}

==Successful BIOS Modifications==
{{WARN|This table is meant to give users an idea of what models have been successfully modified and how. As stated before, it is dangerous to mess with your BIOS, you can easily make your machine unbootable. Please proceed with caution!}}

==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.

|-style="background: white;"
|13
|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.

Reference:<br>

[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.}}

How to make use of Dynamic Frequency Scaling

2006-06-07T13:29:53Z

Ruena: name of governors modules

==General==
Linux supports dynamic frequency scaling for systems with the following processors:
*[[Intel Mobile Pentium III]]
*[[Intel Mobile Pentium III-M]]
*[[Intel Mobile Pentium 4]]
*[[Intel Mobile Pentium 4-M]]
*[[Intel Pentium M (Banias)]]
*[[Intel Pentium M (Dothan)]]
*[[Intel Core Solo (Yonah)]]
*[[Intel Core Duo (Yonah)]]
*Mobile Athlon
*AMD64
*Opteron

==Configuring the Kernel==
===2.4 Kernels===
There were various frequency scaling implementations in the 2.4 series of kernels. They all were preliminary and a standard was rised with the introduction of the sysfs filesystem in 2.6 kernels. It is recommended to use a 2.6 kernel, if possible.

===2.6 Kernels===
You need to enable the cpu frequency scaling for your kernel (usually your distros kernel will have this enabled):
:{{kernelconf|CONFIG_CPU_FREQ|<*>|||||}}

You need to enable governors, if not already done in your distros default kernel:
:{{kernelconf|CONFIG_CPU_FREQ_GOV_PERFORMANCE|<*>|||||}}
:{{kernelconf|CONFIG_CPU_FREQ_GOV_POWERSAVE|<*>|||||}}
:{{kernelconf|CONFIG_CPU_FREQ_GOV_USERSPACE|<*>|||||}}

Since 2.6.10 there is the ondemand governor that does cpu frequency scaling in kernel and can be used as an alternative to powernowd etc.
It can be enabled with:
:{{kernelconf|CONFIG_CPU_FREQ_GOV_ONDEMAND|<*>|||||}}

Since 2.6.12 there is the conservative governor that works similar to the ondemand governor.
:{{kernelconf|CONFIG_CPU_FREQ_GOV_CONSERVATIVE|<*>|||||}}

ondemand and conservative differ in the way they scale up and down. The ondemand governor switches to the highest frequency immediately when there is load, while the conservative governor increases frequency step by step. Likewise they behave the other way round for stepping down frequency when the CPU is idle.

==Using the Sys Interface==
The files in {{path|/sys/devices/system/cpu/cpu0/cpufreq/}} provide information and a means of controlling the frequency scaling subsystem.
Seed values are given in Khz. You need to be root to access the /sys filesystem.

Your max speed is at {{path|/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq}}.
:{{cmdroot|cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq}}
:{{cmdresult|700000}}
Your min speed is at {{path|/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq}}.
:{{cmdroot|cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq}}
:{{cmdresult|500000}}
If you are using the userspace governor, you can write to {{path|/sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed}} to change the current speed.
:{{cmdroot|echo 700000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed}}
:{{cmdroot|cat /proc/cpuinfo | grep "cpu MHz"}}
:{{cmdresult|cpu MHz : 697.252}}
:{{cmdroot|echo 900000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed}}
:{{cmdroot|cat /proc/cpuinfo | grep "cpu MHz"}}
:{{cmdresult|cpu MHz : 976.152}}

==Using Frequency Scaling Governors==
You can compile the scaling governors into your kernel or compile it as module. You'll find the governors with 'make menuconfig' here:
:{{kernelconf||||CPU Frequency scaling|Power management options (ACPI, APM)|||}}

After booting the new kernel you can get a list of available governors with (as root):
:{{cmdroot|cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors}}
:{{cmdresult|conservative ondemand powersave userspace performance}}

Note: If the governors are compiled as modules, load them first:
:{{cmdroot|modprobe cpufreq_performance cpufreq_ondemand cpufreq_conservative cpufreq_powersave cpufreq_userspace}}

A Short Overview over the available governors:
:;ondemand
::This driver is a dynamic cpufreq policy governor. It changes frequency based on the processor load and may not work on older laptops without Enhanced SpeedStep due to [http://lists.debian.org/debian-powerpc/2005/05/msg00542.html latency reasons].
:;conservative
::New since 2.6.12. Similar to ''ondemand'' but has a much slower 'slew rate', remaining at high frequency for many seconds after recent processor demand. Good for battery powered environments and AMD64. Again, this governor may not work on older ThinkPads like the T21.
:;powersave
::Like the name says, your battery would choose this one ;). It sets the Frequency always to the lowest available.
:;userspace
::You have to choose this one, if you want to set the frequency manually. Some [[#Using Frequency Scaling Daemons|frequency scaling daemons]] require this governor to operate correctly. This will typically be the recommended one with older processors like A30p's pIIIm-1200.
:;performance
::This governor sets your Frequency always to the highest available.

Now we set our governor:
What is our current governor?
:{{cmdroot|cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor}}
:{{cmdresult|userspace}}
Set new governor and watch if it has changed
:{{cmdroot|echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor}}
:{{cmdroot|cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor}}
:{{cmdresult|conservative}}

Congrats! Your governor is active.

You may set the governor in your rc.local, to make it used on every boot.

==Using Frequency Scaling Daemons==
Frequency Scaling Daemons adapt the frequency policy to different situations. A typical configuration would be to use the ondemand governor running off batteries and performance otherwise, or combining powersave with conservative on laptops with heat problems. More sophisticated setups adapt to battery level, CPU temperature or even running programs. Some daemons are able to control other power management features like hard disks or graphic cards.

{{NOTE|Daemons are optional. If you don't plan to change policies depending on the situation, you don't need one and you can stick to the <tt>ondemand</tt> or <tt>conservative</tt> frequency scaling governors, available in kernels after 2.6.10 or 2.6.12 respectively. See [[#Using Frequency Scaling Governors|above]]. They require less configuration and have generally been experienced to flawlessly adapt to the situations at hand.}}

Some daemons use the kernel governors (see above), others implement the functionality on their own. In the latter case you have to enable the userspace governor. If it is built as module, load it as <tt>cpufreq-userspace</tt>.

There are plenty of userspace frequency scaling daemons available:

*[[How to configure cpudynd | cpudynd]]
*[[How to configure cpufreqd | cpufreqd]]
*[[How to use cpufrequtils | cpufrequtils]]
*[[How to configure powernowd | powernowd]]
*[[How to configure powersaved | powersaved]]
*[[How to configure speedfreqd | speedfreqd]]

==Debian notes==
Instead of compiling your own kernel, you can use the {{Debian}} "stock" kernel. In Unstable/SID the 2.6.12 kernel image with an {{path|/etc/modules}} file that includes:

battery
ac
thermal
processor
acpi-cpufreq
cpufreq-userspace

With the powernowd package and you should be setup.

{{Debian}} has no {{path|rc.local}}, so read [http://www.debian.org/doc/FAQ/ch-customizing.en.html#s-custombootscripts this] and [http://www.debian.org/doc/FAQ/ch-customizing.en.html#s-booting this].

A better alternative for Debian than modifying bootscripts, is to install the [http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&version=all&exact=1&keywords=sysfsutils sysfsutils package]. Then edit {{path|/etc/sysfs.conf}} (as root), where you can setup values to sysfs entries that you want to be modified automatically on boot.

==Troubleshooting==
*If you have a Coppermine-piix-smi based ThinkPads like from the A2x, X2x and T2x series you need to enable the <tt>speedstep-smi</tt> driver in the kernel and load it if it's built as module. You might want to look at [[How to get SpeedStep working on Coppermine-piix4-smi based ThinkPads | this page]].

*If you have a p4-class celeron based ThinkPad like the R40e you might want to look at [[How to get SpeedStep working on P4-class-Celeron based ThinkPads | this page]]

*You may need to set your BIOS to "maximum performance" if you are using Linux to set the CPU speed. This is necessary to prevent odd behaviour (cpufreq 'freezing' at certain frequencies) with the T4x series.
