Talk:Problem with unauthorized MiniPCI network card

2008-03-30T19:21:42Z

Jstergis:

== Solution for R32, T43, T6x ==
Basically solved [http://forum.thinkpads.com/viewtopic.php?t=55837 here]. Will be finalized into some user-friendly thing hopefully.

== Affected Models ==
I am unsure about which models this applies to. I have seen reports of this problem affecting a T41p, T43, X40, R31, X31, and T30; but I do not know how far back this problem goes or if there are exceptions. If anyone has better information, please clarify/specify the "Affected Models" section. --[[User:Kevinoid|Kevinoid]] 05:44, 14 Dec 2005 (CET)

I have a R40 model 2681-K9G that came without any mini-pci card so I bought a Intel PRO/Wireless 2915ABG mini-pci card for it. When I discovered that it would not work in my Thinkpad I came to this site to see if there was a fix. Seemed like there was, so I bought a mini-pci-to-PCI adapter and installed the card(s) in my desktop. Now I need to know what vendor and device ID strings to use when I flash the card's BIOS. Anyone have a list?

== Solution on T43? ==
There were several edits to the previous page to the effect that "this didn't work for my T43". Although I do not weight this as highly credible (please just ask for help on the ML rather than adding random comments to pages), I did feel that it deserved a mention that the solution may not work on the T43. If anyone can confirm or deny this statement, please do so (and possibly ask on the ML for solutions if it does not work for you). --[[User:Kevinoid|Kevinoid]] 05:44, 14 Dec 2005 (CET)

== Confirmation - patch not working on T43 ==
I can confirm, that a "nvram/cmos" patch is not working on my T43, exact type 1871-A62. I tried several cards (some working without patch in another thinkpads (t40, t42, x40), but no success.--[[User:Jap|Jap]] 09:50, 13 June 2006 (CEST)

== Hotplugging PCI device ==
I'd like to send out a '''BIG FAT WARNING''' that 'hotplugging' the mini-PCI card can easily lead to frying the system board, mini-PCI bus, or both. Yes, it happened to me... :-( Interrupting the boot process at the lilo boot menu, and then inserting the ipw2915abg card worked as a charm to circumvent the BIOS white list. However, somewhere it must have gone wrong because now the laptop hangs immediately when the IBM/Intel boot logos appear. --[[User:LJSBrokken|LJSBrokken]] 13:01, 20 July 2006 (GMT+1)

== Z60 series ==
I tried this on a Lenovo Z60t. Bought an Intel Wireless card since the linux drivers for the madwifi are crap. I applied the C-Patch from here. Then after booting with the intel device installed I get some weird broadcom PXE boot messages displayed ontop of the key symbol for startup security. Even if I don't put my finger on the sensor, it continues with GRUB. At this point I can't use the keyboard, the key symbol is still displayed in the upper left corner. After a few secons grub starts with its default entry (Gentoo Linux). It all works, but no Wireless Adapter shows up in lspci.

So, I don't have that 1802 error, but still can't use my wifi card. Any ideas?

== G40 series ==
According to [[http://www.wifi-forum.com/wf/showthread.php?t=60620|this forum post]], the CMOS hack (I assume they are referring to the bit-twiddling code) works. Does anyone else have anything to confirm this? I might well try it myself (in which case I'll update the main table), but I'll have to at least get an aerial first.

== no dice on T43 ==

Also can confirm the T43 is much more resistant to the unauthorized mini pci card problem. No 1802 didn't work (it worked for my T40). Changing the PCI class id to 0x0280 (networking device - other) also didn't shake the message. Finally, I tried to masquerade the card as a one of the whitelisted ones via the ath_info utility from madwifi. I made a mistake at this point and didn't update the subsystem vendor id / subsystem device id, just the primary pci vendor and device ids. I *still* got the warning message, and now the ath driver doesn't pick up the card, so I can't use ath_info. The card is basically bricked, unless I find time (ha ha) for some kernel hacking. Moral of the story is be careful with ath_info.

You should be able to use ath_info _without_ the madwifi driver use some low level pci tool to manually configure the card. Have a look into the source code comments at the begin of ath_info.c. On the other hand adding a new set of vendor ids in the madwifi driver isn't a big deal either. - [[User:jal2|jal2]]

== IBM R40e ==

Have an IBM R40 & R40e, R40 - linux no-1802 cd worked flawlessly, r40e - linux no-1802 cd - hangs on confirmation the patching - maybe a keyboard error, but I dont have dock nor USB keyboard to try, the DOS CD, worked perfectly on the r40e (although I was a little nervous about bricking the R40e ;-). A little note - the r40e obviously dont have an antena - i'll have to get some, but its working even without antena for short range indoor (the accesspoint is about 3 meters away)

== Other issues with unauthorized cards ==

I'm not sure if this is common but my Intel Pro 2915ABG (not from IBM) works on my T41 (both from eBay so some patch was probably already applied) except that the WLAN LED on the laptop stays off all the time. If this is common to all non-authorized cards, this wiki article should mention this. (yak - 24.01.2004)

It does the same for my r40 and not IBM intel 2200, I think that the led would work only if the PCI ID of the minipci card would be changed to IBM, but i dont know excatly how to do this, I just remember seeing it somewhere (kajencik - 24.01.2008)

I now know that someone changed the PCI-ID of my Intel 2915ABG card so it looks like an IBM one. Yet the LED didn't work. However, I've found a way to fix this: [http://forum.thinkpads.com/viewtopic.php?p=395350#395350 see here]. Changing PCI-ID is quite easy, see [http://stachon.webpark.cz/ipw-eeprom.html this] (also helpful: '''Patching the EEPROM''' section of [[Ipw2200]] article). (yak - 4.03.2008)

I've added a new section called "Problem with WiFi LED". Comments and contributions are welcome. (yak - 5.03.2008)

== IBM Thinkpad R31 ==

I have the BIOS hacked in my R31 so it boots with the unauthorized card and XP picks it up, but XP will randomly lock up with the current card (Atheros 5005G) I have tried another of the same chipset and it does the same thing. What I shall try soon is to swap the 5005G with a friend for a Realtek card from his laptop. Does anyone know if there is an incompatibility issue with Atheros card in the R31?

Problem with unauthorized MiniPCI network card

2008-03-30T19:18:23Z

Jstergis: /* 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.}}

* 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}}

{{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.

|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.}}
