Over time, different ThinkPads have used different power connectors. You can use a higher Amperage rated power supply then your ThinkPad needs, as long as the physical connector is correct. But you should not use a lower Amperage power supply on a ThinkPad needing more Amperage. Doing so will overheat the power supply, and might cause issues such as screen flicker.

{{HINT|In case you cannot find your Model ThinkPad listed, or you wish to double check, you can find the required power information on a label on the bottom of your ThinkPad}}

{{NOTE|The Amperage's listed below are the OUTPUT values for the AC adapter, which should be equal or greater then what your ThinkPad requires}}

All current Thinkpads require 20 Volt DC input. See also the official Lenovo page for power adapters {{LNVDOCURL|PD014168|Lenovo Alias ID: AC-ADAPTERS, Document ID: PD014168, Last Updated :02 Sep 2016}}. (Was {{IBMDOCURL|MIGR-4tcmcu|IBM Doc MIGR-4tcmcu}}.)

{{NOTE|This information '''is incomplete''' and not entirely correct.}}
{{Todo|add pinout}}
The information found in this page is mostly correct. But the four-pin connector, in particular, is not thoroughly understood. This connector is [http://forum.thinkpads.com/viewtopic.php?f=6&t=112233 discussed on forum.thinkpads.com, "Correct type of power supply for 360Cs"].
[[image:4pin-power-plug.JPG|right|thumb|4 pin power connector]]

==A makeshift replacement connector==
As these 4-pin PSUs are getting more rare and more expensive, a cheap solution if you don't have one is to adapt a universal 19-20V laptop PSU with a barrel connector. This isn't ideal if you're relying on the Thinkpad for some critical old business application, but it's fine if you're just a tinkerer playing with an old one off eBay for example.

Only the "+" and "-" connections (top-right and bottom-right looking into the connector on the back of the laptop from the back of the laptop) are required for basic operation, so that's all you need to adapt.
Get an extension lead for your barrel connector - e.g. 2.1mm - and cut it in half. Discard the plug half.
Get a '''"Mini JST" plug''' with flying leads, commonly used to power model helicopters etc. This is the plug that I've found will fit over the + and - pins.
Wire the two together so that the red wire on the Mini JST is soldered to the centre contact wire on the barrel connector extension (socket half).

ALWAYS double check the polarity when plugging in your custom modded connector, since it's possible to get it the wrong way round.--[[User:Cloudane|Cloudane]]

==plug converter for universal power adapter==
[[File:4-pin_hexagon_plug_converter_S-l300.jpg|right|thumb|convertor from barrel to 4pin hexagon plug]]
An aftermarket plug converter is available, alone and in a set, which fits IBM's hexagonal inlet. It is meant to be used with an Universal AC Adapter (of cheap ''China Special'' variety). It is not safe to use. In this converter, both '''G''' and '''-''' are wired to the outer shell of the barrel connector, and both '''S''' and '''+''' are wired to the centre pin of the barrel connector. In some ThinkPads (specifically {{760E}}), '''S''' and '''-''' pins are connected to each other. This plug will make a short circuit in such a ThinkPad.

{{QUOTE|kishy|forum.thinkpads.com|Internal to the ebay DC port adapter, the (G) and (-) terminals have continuity, and the (S) and (+) terminals have continuity. Therefore, if you connect the ebay port adapter to the laptop, you are shorting positive to negative.}}

The size of this connector is same as on usual 20V AC adapters, but inner detail is different. Inside this connector is not round any more: it has two symmetric plastic knobs. A user can only plug it in two particular orientations. The extra knobs prevent one from using the AC adapter with any other Thinkpads.

Rbs45: Split T61,T61p on separate line from R61, due to many Type-questions online

''[http://ali.dj/blog/sata-ii-support-for-lenovo-thinkpad-t61-x61-r61 This short description of Middleton's BIOS was written by Ali.dj, who also archived the files. Many thanks.] We've also uploaded Middleton's BIOS to the Internet Archive, so they wouldn't get lost ever again.''

[http://forum.notebookreview.com/lenovo-ibm/459591-t61-x61-sata-ii-1-5-gb-s-cap-willing-pay-solution-8.html#post6501443 Notebookreview.com-forum] user 'middleton' created a modified BIOS which enables SATA II, disables the miniPCI Whitelist (allowing you to use any wifi card), and even contains an optional FN-Ctrl swap. Lastly, if you were brave enough to install an IPS SXGA+ screen on a regular X61, 'middleton' has a BIOS mod that enables it.

SATA II Mod: While the X61/T61/R61/X300 possess a SATA II-interface (up to 3.0 GBit/s) they were limited to SATA I (up to 1.5 GBit/s) in the BIOS to maintain compatibility with older drives. Normal hard drives will rarely max out SATA I speeds, but nowadays, SSDs can handle the full 3.0 GBit/s (and more).

== Installation ==

The flasher is an EXE-file which updates the BIOS directly. Note that the BIOS flasher only works on 32-bit versions of Windows. If you use a 64-bit version or another operating system you have to burn the included ISO-file on a CD or DVD and boot from it. The following table shows the supported Thinkpad-models and the corresponding BIOS-update-files:

'''DISCLAIMER: Use these modified bios at your own risk!'''

These modified bios have been beta tested to confirm they do not brick the system after flash. However data integrity tests take time and it's up to the user to confirm there is no data loss due to the increased SATA-II interface speed. You will be solely responsible for any damage to your computer system or loss of data that results from flashing or using of the patched BIOS.

'''Lenovo has never tested or approved these patched bios and doesn't support them. They are provided "as is" without any warranties from Lenovo. These bios-es are completely unofficial releases.'''

==== SLIC 2.1 ====

Stands for "Software licensing information code" which is a technique used by OEM-computerseller to execute Windows-installations without having to activate it (which is required from Windows XP onwards). SLIC 2.1 is required to use that feature with Windows 7. I don't really need that feature since Windows' product activation doesn't hurt, but especially Windows 7-users without internet-connection (or valid license-key) may appreciate it.

==== whitelist removed ====

If you try to use the MiniPCI Express-slot with Non-Lenovo cards you'll get Error 1802 after starting. This fix removes the whitelist so you can use cards of any manufacturer.

==== Thermal sensing ====

On a few models with Intel Core 2 Duo "Penryn" CPU the user gets a "Thermal Sensing error" upon starting the system which has to be canceled by pressing Escape. This fix removes the error-message.

==== CTRL-FN-Swap ====

You can find the CTRL-key on most notebooks in the bottom left corner of the keyboard. The special function-key (Fn) is on its right side. On Lenovo-notebooks this is interchanged. A lot of user with multiple notebooks don't like this so you can revert the order with this fix. You can choose this by using the other BIOS-update-files (which you find in the ZIP-package). I did it and after getting used to it for a while it is now more pleasant to have the same behaviour on all keyboards.

==== Acknowledgments ====

* nando4 for providing all needed information on SATA-II mod. I knew nothing about this issue in 2010 and didn't plan to make any ThinkPad BIOS mods (except for CTRL-FN swap). It was him who convinced me to solve SATA-II problem. Also he literally forced me to add dual-IDA support (he knows what I'm talking about :)). <br> andyp for his BIOS modding tools and other guys from forums.mydigitallife.info for making SLIC 2.1 integration possible.
* Zender for finding the way of disabling wireless whitelist on ThinkPads. This significantly accelerated the work on the patch (otherwise I would have had to do it myself and it would have taken additional time).
* Leokim for X61/X61s SXGA+ BIOS.
* XStoneX for informing me about "Thermal Sensing Error". <br> unclewebb for the ThrottleStop utility which makes dual-IDA possible and kizwan for the "EIST Unlocked Example" guide.
* Brave ThinkPad owners for readiness to test intermediate BIOS versions.

Power Connector

Over time, different ThinkPads have used different power connectors. You can use a higher Amperage rated power supply then your ThinkPad needs, as long as the physical connector is correct. But you should not use a lower Amperage power supply on a ThinkPad needing more Amperage. Doing so will overheat the power supply, and might cause issues such as screen flicker.

{{HINT|In case you cannot find your Model ThinkPad listed, or you wish to double check, you can find the required power information on a label on the bottom of your ThinkPad}}

{{NOTE|The Amperage's listed below are the OUTPUT values for the AC adapter, which should be equal or greater then what your ThinkPad requires}}

All current Thinkpads require 20 Volt DC input. See also the official Lenovo page for power adapters {{LNVDOCURL|PD014168|Lenovo Alias ID: AC-ADAPTERS, Document ID: PD014168, Last Updated :02 Sep 2016}}. (Was {{IBMDOCURL|MIGR-4tcmcu|IBM Doc MIGR-4tcmcu}}.)

=4-Pin hexagon=
{{NOTE|This information '''is incomplete''' and not entirely correct.}}
The information found in this page is mostly correct. But the four-pin connector, in particular, is not thoroughly understood. This connector is [http://forum.thinkpads.com/viewtopic.php?f=6&t=112233 discussed on forum.thinkpads.com, "Correct type of power supply for 360Cs"].
[[image:4pin-power-plug.JPG|right|thumb|4 pin power connector]]

==A makeshift replacement connector==
As these 4-pin PSUs are getting more rare and more expensive, a cheap solution if you don't have one is to adapt a universal 19-20V laptop PSU with a barrel connector. This isn't ideal if you're relying on the Thinkpad for some critical old business application, but it's fine if you're just a tinkerer playing with an old one off eBay for example.

Only the "+" and "-" connections (top-right and bottom-right looking into the connector on the back of the laptop from the back of the laptop) are required for basic operation, so that's all you need to adapt.
Get an extension lead for your barrel connector - e.g. 2.1mm - and cut it in half. Discard the plug half.
Get a '''"Mini JST" plug''' with flying leads, commonly used to power model helicopters etc. This is the plug that I've found will fit over the + and - pins.
Wire the two together so that the red wire on the Mini JST is soldered to the centre contact wire on the barrel connector extension (socket half).

ALWAYS double check the polarity when plugging in your custom modded connector, since it's possible to get it the wrong way round.--[[User:Cloudane|Cloudane]]

==plug converter for universal power adapter==
[[File:4-pin_hexagon_plug_converter_S-l300.jpg|right|thumb|convertor from barrel to 4pin hexagon plug]]
An aftermarket plug converter is available, alone and in a set, which fits IBM's hexagonal inlet. It is meant to be used with an Universal AC Adapter (of cheap ''China Special'' variety).

WARNING: do NOT use this adapter, it has two + and two - connectors, which will cause a short in your laptop.

The size of this connector is same as on usual 20V AC adapters, but inner detail is different. Inside this connector is not round any more: it has two symmetric plastic knobs. A user can only plug it in two particular orientations. The extra knobs prevent one from using the AC adapter with any other Thinkpads.

===Battery health===
Batteries, especially of the modern Li-Ion type, wear out quicker when they hold a large charge or are subject to higher temperatures (see above).

If you use your laptop at a desk, reduce battery wear by maintaining an appropriate charge level. When possible, remove Li-ion batteries while operating from AC as the notebook gets hot enough inside for that to damage the battery in the long run, even if charging is stopped.

On recent ThinkPads, charging thresholds can be configured in the bundled software. Under Linux, this is supported on recent models by the [[tp_smapi]] driver (and even without <tt>tp_smapi</tt>, if you have a dual-boot setup, you can set the thresholds under Windows and they will be remembered as long as you don't power off your machine with AC disconnected; suspend to RAM is OK). Have a look at [[How to use UltraBay batteries]].

If you have spare Li-ion battery packs, store them at 40% charge in a cool place (15C being a recommended temperature, do not let the batteries freeze). If storing inside a refrigerator, beware of humidity, and be careful with cold spots that can easily freeze the battery if anything goes wrong.

===The problem with 600 series batteries===
ThinkPad 600 power management causes batteries to die before they should. Read more about this on the [[Problem with ThinkPad 600 batteries|associated problem page]].

===Reviving batteries===
Some people experience sudden drops in their batteries capacity. A way to get these batteries back to full capacity is to run the "Battery Rundown" function of IBMs "PC Doctor for DOS". The program is downloadable from IBMs support site as three floppy disk images. Make sure you get the specific version of program made for your ThinkPad model. For those who do not have a floppy, David Smith prepared a [http://www.mypchelp.com/~dsmith/ibmutil/ibm_t22_pcdiag.iso bootable CD image] (dead link, a copy is also available [http://server6.org/~marker/software/ibm_t22_pcdiag.iso here]) from the T22 floppy images. For newer ThinkPads there is an official [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-56222 bootable CD image]. (Although the instructions on this page (as of May 2008) include details for Linux and refer to a CD image, it is actually provided as a Windows executable. On Linux systems, [http://winehq.org Wine] can execute this file and extract the CD image.) Once extracted, you must mount the iso as a loop device (as root) like so:

:{{cmdroot|mount -o loop 1ety48ww.iso /mnt/floppy}}

Then copy the .IMA file out of that mounted iso:

:{{cmdroot|cd /mnt/floppy}}
:{{cmdroot|cp 1ETY48WW.IMA /boot}}

(Or to some other suitable directory.) After this, you can follow the same directions that apply for [[BIOS Upgrade|BIOS upgrade]]s.

{{NOTE|This will do nothing to improve the performance of a dying battery. It serves only to recalibrate the battery charge controller. The "Battery Rundown" function of IBMs "PC Doctor for DOS" has no intelligence. It merely runs a series of dumb operations to consume battery power, and it cannot detect whether a battery is present or not. If you leave the mains connected while running "Battery Rundown", it will have no effect, as the battery will simply keep charging. The [[tp_smapi]] module, if installed, will report the number of charge cycles the battery has had since it was manufactured. If that number is high, the battery's poor performance is almost certainly due to its age.}}

I have recently made an interesting discovery, I have an R40 with two main batteries, both of them have aproximately about under 200 cycles and are nowadays 4 years old, projected capacity for R40/R32 main battery is 57Wh, and both my batteries were about 30Wh, then I left my notebook with one of them about a day in a standby mode, as long as it powered off itself because of low battery power, when I turned it on I saw the battery capacity at about 42Wh, then, I did this too for the second battery and I got even about 46Wh, I think I could go even higher with letting the battery discharge completely from 100% in standby, I think this has something to do with low power consumption in standby mode, it may work for you too.

==Cleaning the Interior==
{{WARN|The following instructions are not appropriate for all ThinkPad models. Please consult the hardware maintenance guide or on-line disassembly instructions for your model.}}
Most ThinkPad models (particularly the A-series and the T-series) tend to accumulate a lot of interior dust which they draw from their ventilation fan. A good dusting every few months is advised. The procedure is as follows.

===ThinkPad T4x series===
See IBM's keyboard removal [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-46515 instructions] and [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-50227 movie].

===Other models (which?)===
#Unplug the computer.
#Remove the battery.
#Turn the ThinkPad over and find two to three screws with upraised double-arrows pointing to them.
#Unscrew these screws and set them aside.
#Press the silver area underneath where the battery used to be. The front of the keyboard will pop up.
#Turn the ThinkPad right side up and gently remove the keyboard, pulling it toward you.
#There is one connector between the ThinkPad and the keyboard. Disconnect it, and set the keyboard aside.
#If there is a small black plastic separator under the keyboard, remove it and set it aside.
#The fan should be visible in the upper left. That entire area will likely be dusty. With a can of compressed air (and ''only'' with a can of compressed air), dust that area and the surrounding area.
#Replace the small black plastic separator, then reconnect the keyboard.
#Slide the keyboard back into place, then press down on the Fn and right-arrow keys until it pops into place.
#Replace the keyboard screws and battery.

==Dealing with spilling accidents==
#Don't panic.
#Don't flip or tilt the computer to prevent the liquid from spreading all over the inside of the case.
#Shut down the OS and turn off the power:
##Unplug the computer.
##Remove the battery.
#Tilt the computer so that everything that leaked into the case can flow out the same way.
#Allow the computer to dry before switching it on again.
#For minor accidents this might already be sufficient. For major flooding you should either bring the computer to a dealer who knows how to open and clean it from inside. Or you can read the Hardware Maintenance Manual, open, clean, and dry the computer yourself.

==Recovering BIOS passwords.==
Password recovery procedure for IBM ThinkPads using R24RF08 and IBMpass.

(Note: An updated tutorial can always be found [http://www.allservice.ro/forum/viewtopic.php?t=47&start=0 HERE])

'''1. Introduction.'''

The IBM ThinkPad uses a small eeprom ([[AT24RF08|ATMEL 24RF08]]) to store different OEM
issues like serial number, UUID, etc. The supervisor password (SVP) is also stored in this eeprom.
The 24RF08 is not an ordinary eeprom: it features read protection, which the BIOS uses to lock down
access to the eeprom contents. Also, the password is written in a special scan code, which needs to
be translated to ASCII to be of any use.

To recover the password, one can use two different programs: R24RF08 (eeprom reader) and IBMpass
(password revealer) available at [http://www.allservice.ro/store/utils http://www.allservice.ro/store/utils]. Diagrams are included in the reader kit.

Models for which R24RF08 and IBMpass are enough to recover the password: 240, 240X, 390E, 390X, 570, 570E,
600e, 600X, 770Z, A20m, A21e, A21m, a22m, A30, A30p, A31, A31p, G40, G41, R30, R31, R32, R40, R50, R51,
Transnote, T20, T21, T22, T23, T30, T40, T40p, T41, T41p, T42, T42p, X20, X21, X22, X23, X24, X30, X31, X40, X41, X61.

ThinkPads featuring TPCA technology (i.e. a [[Tpm|TPM trusted platform module chip]]), especially T4x, X3x, X4x, X61 and X61T need the W24RF08 eeprom writer program to complete the password recovery procedure, if the passphrase function is enabled in BIOS setup.

Other models such as the 380XD or 600 use 24C01 or 93C46 eeproms, which can be read without special tools.
The method is the same like for the models based on 24RF08, only the software to dump the eeprom is different.

Newer T43/T43p, R52, R60, T60/p, X60 and Z60 ThinkPads can be unlocked using PC8394 programming tools that consist in RPC8394 and WPC8394 (reader and writer for TPM chips).
The software is available as well at [http://www.allservice.ro/forum/viewtopic.php?p=1061#1061 www.allservice.ro]. IBMpass 2.0 works for any TP model without exceptions.

'''2. Locating the ATMEL 24RF08 eeprom. Soldering.'''

No need to unsolder the 24RF08 eeprom, just solder 3 wires to SDA, SCL and GND pins of the
eeprom. There are two eeprom layouts (see interface schematics described bellow), corresponding to 8 pin or 14 pin eeproms. Locate the eeprom first according to your model (E.g. T20-23 and T30 have the eeprom underneath TP, and can be accessed by removing the RAM modules cover, no need to dismantle the laptop.) and solder the wires using a soldering iron with a fine tip. Also, you can use 0.15 -0.20 mm enamel coated wires or similar small diameter insulated wires. These wires will be connected later to the interface.
Tip: You can use clips to connect the wires or you can solder on the PCB traces leading to the
eeprom pins. Once again, be careful and double, triple check the soldering if necessary till you are positively sure you have done the right job. In case of applying too much solder, use flux-impregnated copper-braid "desoldering wick" - this works exceptionally well.

'''3. Choose and build the interface.'''

Since version 2.0, R24RF08 and W24RF08 (eeprom writer) are compatible with a wide range of eeprom programmers. By default, both programs set the COM port signals to use direct logic level to access I2C bus. We provide here 2 schematics that are relevant for direct logic signals and for inverse logic signals (simple-i2cprog.pdf and driven-i2cprog.pdf). Also, depending of the interface you build, you can invert the logics for SDA-In, SDA-Out, and SCL COM port signals by some command line parameters described later in this document.
a) The file simple-i2cprog.pdf contains the schematic diagram of a simple interface (known as SIPROG)based on 2 zeners and 2 resistors. This is a classic, easy to build circuit and works with soldered or unsoldered eeproms. The purpose of the 2 zeners is to convert RS232 levels (+/- 5V) to TTL levels, needed by the eeprom. It uses direct logic signals to I2C eeprom and is powered by the COM port. However, this interface works with in-system eeproms but is dependant on COM port current and eeprom bus impedance. R24RF08 works natively with this circuit, no need to change the lines signals with command line parameters. This circuit works pretty well with almost all ThinkPads series.
b) The second interface is described in driven-i2cprog.pdf. The circuit uses MAX 232 as a RS232 to TTL driver and its main purpose is to work with soldered eeproms. The advantage of MAX232 is the TTL outputs that are more reliable and more powerful when work with soldered, in-system eeproms (dependency free from the COM port current). Due of the internal inverters of MAX232 the interface responds to an inverse signal logic level. R24RF08 needs /x, /d, /i switches to be specified in the command line.

What these switches mean:
/x - invert serial clock, also known as SCL;
/d - invert serial data output, also known as SDA-Out;
/i - invert serial data input, also known as SDA-In.
All those can be used in any combination to meet any interface specification.

Note that the "standard" serial port programmer probably won't work with a USB-Serial adapter, but requires the full nominal voltage of a hardware serial port. [Example: the A22p's serial port works fine here.]

'''4. Dump the EEPROM:'''

Prepare your technician PC by connecting the interface to the COM1 port (donâ€™t connect the wires to eeprom yet). Turn on the ThinkPad and press F1 to enter BIOS Setup. When you are prompted for the password and thereâ€™s no other activity like HDD access or so, connect the wires (GND first!, SDA, SCL) to the corresponding wires from the interface (attached before to COM1) and execute R24RF08:

-for SI-PROG interface (as described in 3.a above):
r24rf08.exe <filename.ext>. where filename.ext is the file where eeprom content will be stored.
Example: r24rf08 mytp.bin

-for MAX232 driven I2C interface (as described in 3.b above):
r24rf08.exe <filename.ext> /x /d /i. where /x /d /i are command line parameters (switches) for this kind of interface.
Example: r24rf08 mytp2.bin /x /d /i

Use exactly the instructed switches to avoid possible damages to your eeprom data!
The file should be created in the same folder. Finally, disconnect the wires (GND last!) and turn off the ThinkPad by pressing on/off switch.

Dump the EEPROM data at least twice, and do a bytewise compare with `cmp`. Both files should be identical, and 1024 bytes long. Otherwise, you probably have a serial port problem.

Note: the r24rf08.exe program automatically sets the serial port parameters. It also works fine with Wine under Linux - provided that a symlink (com1) exists in the .wine/dos_devices directory, and points to the /dev/ttySX for the actual serial port.

'''5. Reveal the password.'''

Now, you have the .bin file but you need to dump in scan code to retrieve the password. IBMpass 2.1 Lite is a free tool that will do the job. Just open the eeprom dump youâ€™ve created before and search for 0x330, 0x340 lines. The password is located on 0x338 (and 0x340 depending on model) in scan code. For 24C01 eeproms the password is located at 0x38, 0x40. If the password won't work for the very first time then your eeprom may use newer IBM scancodes. In this case switch to alternate scan codes to find it. For those who want quick answers the recommended version is IBMpass 1.1. Usage for IBMpass 1.1 (command line only):

ibmpass mytp.bin â€“ use â€œ/aâ€ switch to see in alternate scan code if needed:
ibmpass mytp.bin /a

For some old models like 570 or 770Z you need to execute the eeprom patcher first. This will reset the read protection on the password offset. To do that just execute patcher.exe before the reading operation, without rebooting the laptop:

-for SI-PROG:
patcher.exe , then immediately
r24rf08.exe <filename.ext>

-for Driven-I2C (Max232) you must insert the switches:
patcher.exe /x /d /i, then immediately
r24rf08.exe <filename.ext> /x /d /i

W24RF08, the writer version, has included the complete APP reset operation you donâ€™t need to use patcher.

Moreover, there are a new encrypting algos used with some new security chips (AT97SC3201, AT97SC3203) that are very secured. The password is not in scancode and in some cases not even in the eeprom. To unlock the machine, the dump should suffer some changes and the eeprom must be reprogrammed using W24RF08. This operation works for all IBM TCG/TCPA secured laptops w/o exceptions.

Remember, use 3 wires from the interface and 3 wires from eeprom! Connect them after your
ThinkPad is powered and disconnect them right after you read the content, before you switch off the laptop.

'''6. Password format'''

The thinkpad power-on/supervisor passwords are a maximum of 7 characters, and are NOT case-sensitive. The allowed characters are restricted to A-Z, 0-9, semicolon, _, - (and perhaps a few others).
If PassPhrase is enabled then the password can be longer than 7 characters.
Models like T43/R52/T60/R60/T60/X60/Z60/Z61 need the TPM chip dumped with [http://www.allservice.ro/forum/viewtopic.php?p=1061#1061 PC8394 programming tools] in order to find password/reset the TCPA lock.

Problem with error 01C9 - More than one Ethernet devices

2008-09-08T13:11:14Z

Rbs45: /* Solution */

==Problem Description==
Certain ThinkPads show a warning message during [[POST]] when a WLAN card with an Atheros chipset is present in the MiniPCI or PCMCIA slot:

WARNING
01C9: More than one Ethernet devices are found. Remove one of them.
Press <Esc> to continue.

Also, boot-up during POST may be taking longer than expected.

At POST, the BIOS conducts a scan for ethernet devices. It does this by reading the "PCI Class Codes" of every connected device. If more than one ethernet device is found, it produces the 01C9 error message. Unlike other wireless cards, which identify themselves as "other" network adapters, Atheros classify themselves as "ethernet". This collides with the internal ethernet controller (also a PCI device) and causes the 01C9 to appear. BIOS processing of the situation and generating the error message noticeably slow down boot-up time, at least in some models.

== Affected Models ==
* ThinkPad {{A31}}, {{A31p}}
* ThinkPad {{T23}}, {{T30}}
* ThinkPad {{R32}}, {{R40}}
* ThinkPad {{X22}}, {{X23}}, {{X24}}, {{X30}}

'''Not affected are'''
*ThinkPad T4x series
*ThinkPad X4x series

== Solution ==
The solution is to modify the Atheros EEPROM so that the card correctly identifies itself as an "other" instead of an "ethernet" network adapter. A Linux Live CD that automates this and can also remove the 1802 error message is now available.

{{WARN|This software was designed FOR ATHEROS CARDS ONLY. Even though most users confirm it working fine, it can potentially harm your computer. The authors are in no way to be held liable for damage caused by this program. There is no warranty given, either express or implied for any fitness for any kind of purpose. YOU AGREE TO USE THIS ENTIRELY AT YOUR OWN RISK. Please also be aware that ath_info is still under development, so be just as cautious with the manual solutions suggested below.}}

NOTICE: The Live CD Version 2 is released now. Download it via Rapidshare [http://rapidshare.com/files/134063984/ibm_wifi_v2.zip here.] (~ 4 MB).
Rapidshare seems not to be working, get it via ''Webfilehost'' [http://www.webfilehost.com/?mode=viewupload&id=9628376 here.] (~ 4 MB).

'''Functionality.''' The 01C9-patch changes the PCI Class ID from 0x0200 to 0x0280, which corresponds "network device: other". It manipulates the Atheros card, not the computer/BIOS/CMOS. It changes neither the PCI vendor ID nor the device ID. Therefore, functionality of drivers and operating systems will not be affected. Uninstalling drivers is not necessary before using this patch. The Live CD auto-detects whether an Atheros adapter is installed and will only then proceed. NOTE: Read the [[Problem_with_unauthorized_MiniPCI_network_card]] article on functionality of the 1802 patch.

'''Usage.'''
# Burn the .ISO file to a CD/DVD. Make sure not to burn it as a file within a filesystem, but as an image.
# If you want to remove the 01C9 error only, skip to step 8.
# To remove the 1802 error, make sure you do not have the Atheros card plugged into the slot.
# Boot from the disc.
# Choose to remove the 1802 error.
# Shut down after pressing Ctrl-Alt-Del.
# Plug in the Atheros card now.
# Boot from the disc (again).
# Choose not to apply the no-1802.
# Choose to apply the 01C9 patch.
# Shut down after pressing Ctrl-Alt-Del. Upon 'cold' reboot, the 01C9 should be gone.

== Limitations ==
Many newer Atheros adapters (chipsets equal to and newer than AR5004x) incorporate an EEPROM write protection by default. The Live CD may or may not be able to automatically patch these devices.

=== Possible solutions ===
Should the automated solution fail, you can try to manually set a GPIO (general purpose input/output) bit to enable write access. Depending on your adapter, this might activate the EEPROM write-enable channel. After the Live CD finishes, it will drop to a Linux shell prompt. Try typing the following:
lspci -vd 168c: |sed -n 's/.*Memory at \([^ ]*\).*/0x\1/p'
This will present you with the EEPROM base address. This you can use to switch the GPIO:
/root/ath_info -g 4:0 -w <base_address>
In this example, you are setting GPIO 4 to low. Restart the patch script to see whether this enabled patching.
/root/patch.sh
After writing you may dump the complete eeprom with "-d" and find the new pci class at (16 bit) offset 2 for verification.

=== Manual method: Ath_info from a LiveCD ===
The Linux Live CD depends on ath_info, a tool derived from the [http://www.madwifi.org Madwifi] Atheros driver project. You can also install ath_info yourself and manually replicate the steps laid out above. If you cannot use ath_info from your current operating system (say if you use [http://www.freebsd.org/ FreeBSD]), you can use [http://grml.org/ grml] to perform this "operation". The grml Live CD contains a C compiler, the Subversion client and loads the Madwifi drivers on boot. So all you need to do is to fetch the source and build ath_info:
svn co http://svn.madwifi.org/ath_info/trunk ath_info

Problem with error 01C9 - More than one Ethernet devices

2008-09-08T13:10:47Z

Rbs45: /* Solution */

==Problem Description==
Certain ThinkPads show a warning message during [[POST]] when a WLAN card with an Atheros chipset is present in the MiniPCI or PCMCIA slot:

WARNING
01C9: More than one Ethernet devices are found. Remove one of them.
Press <Esc> to continue.

Also, boot-up during POST may be taking longer than expected.

At POST, the BIOS conducts a scan for ethernet devices. It does this by reading the "PCI Class Codes" of every connected device. If more than one ethernet device is found, it produces the 01C9 error message. Unlike other wireless cards, which identify themselves as "other" network adapters, Atheros classify themselves as "ethernet". This collides with the internal ethernet controller (also a PCI device) and causes the 01C9 to appear. BIOS processing of the situation and generating the error message noticeably slow down boot-up time, at least in some models.

== Affected Models ==
* ThinkPad {{A31}}, {{A31p}}
* ThinkPad {{T23}}, {{T30}}
* ThinkPad {{R32}}, {{R40}}
* ThinkPad {{X22}}, {{X23}}, {{X24}}, {{X30}}

'''Not affected are'''
*ThinkPad T4x series
*ThinkPad X4x series

== Solution ==
The solution is to modify the Atheros EEPROM so that the card correctly identifies itself as an "other" instead of an "ethernet" network adapter. A Linux Live CD that automates this and can also remove the 1802 error message is now available.

NOTICE: The Live CD Version 2 is released now. Download it via Rapidshare [http://rapidshare.com/files/134063984/ibm_wifi_v2.zip here.] (~ 4 MB). Rapidshare seems not to be working, get it via ''Webfilehost'' [http://www.webfilehost.com/?mode=viewupload&id=9628376 here.] (~ 4 MB).

'''Functionality.''' The 01C9-patch changes the PCI Class ID from 0x0200 to 0x0280, which corresponds "network device: other". It manipulates the Atheros card, not the computer/BIOS/CMOS. It changes neither the PCI vendor ID nor the device ID. Therefore, functionality of drivers and operating systems will not be affected. Uninstalling drivers is not necessary before using this patch. The Live CD auto-detects whether an Atheros adapter is installed and will only then proceed. NOTE: Read the [[Problem_with_unauthorized_MiniPCI_network_card]] article on functionality of the 1802 patch.

'''Usage.'''
# Burn the .ISO file to a CD/DVD. Make sure not to burn it as a file within a filesystem, but as an image.
# If you want to remove the 01C9 error only, skip to step 8.
# To remove the 1802 error, make sure you do not have the Atheros card plugged into the slot.
# Boot from the disc.
# Choose to remove the 1802 error.
# Shut down after pressing Ctrl-Alt-Del.
# Plug in the Atheros card now.
# Boot from the disc (again).
# Choose not to apply the no-1802.
# Choose to apply the 01C9 patch.
# Shut down after pressing Ctrl-Alt-Del. Upon 'cold' reboot, the 01C9 should be gone.

== Limitations ==
Many newer Atheros adapters (chipsets equal to and newer than AR5004x) incorporate an EEPROM write protection by default. The Live CD may or may not be able to automatically patch these devices.

=== Possible solutions ===
Should the automated solution fail, you can try to manually set a GPIO (general purpose input/output) bit to enable write access. Depending on your adapter, this might activate the EEPROM write-enable channel. After the Live CD finishes, it will drop to a Linux shell prompt. Try typing the following:
lspci -vd 168c: |sed -n 's/.*Memory at \([^ ]*\).*/0x\1/p'
This will present you with the EEPROM base address. This you can use to switch the GPIO:
/root/ath_info -g 4:0 -w <base_address>
In this example, you are setting GPIO 4 to low. Restart the patch script to see whether this enabled patching.
/root/patch.sh
After writing you may dump the complete eeprom with "-d" and find the new pci class at (16 bit) offset 2 for verification.

=== Manual method: Ath_info from a LiveCD ===
The Linux Live CD depends on ath_info, a tool derived from the [http://www.madwifi.org Madwifi] Atheros driver project. You can also install ath_info yourself and manually replicate the steps laid out above. If you cannot use ath_info from your current operating system (say if you use [http://www.freebsd.org/ FreeBSD]), you can use [http://grml.org/ grml] to perform this "operation". The grml Live CD contains a C compiler, the Subversion client and loads the Madwifi drivers on boot. So all you need to do is to fetch the source and build ath_info:
svn co http://svn.madwifi.org/ath_info/trunk ath_info
cd ath_info
make
Again, you need to find the address at which your card can be accessed (see above). Once you know it. instead of using the script, run
ath_info -v -w <base_address> pci_class 0x0280
