== 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:
+
 
 +
The ThinkPad BIOS only allows to boot with an "authorized" adapter installed. If an unsupported card is detected, the BIOS prints a message on the screen and stops the system:
  
 
   1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.
 
   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.

{{NOTE|Any of the following solutions should suffice to make the wireless card useable.  You only need to perform one of them.}}
 +
 
 +
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.
 +
 
 +
=== Modifying the card's ID ===
 +
 
 +
A safer and better method than modifying the BIOS is modifying the PCI-ID of the wlan card to match the authorized one:
 +
 
 +
# You'll risk the wireless card instead of the motherboard.
 +
# Future BIOS updates will not create any problems.
 +
# No problem with newer laptops with different BIOS; the only reqirement is to find an ID that is already listed in the BIOS, which can be easily achieved if the community maintaina a compatibility table.
 +
 
 +
The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here] (link down, 2011/05/14 - archive.org mirror [http://web.archive.org/web/20071016063645/http://www.dagarlas.org/stuff/computing/article0001.php here], second mirror [http://www.broken.com/mirror/thinkpad 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://fx.cz/sklad/intel/ 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|On Linux-based distributions, the driver is loaded based on the PCI-ID. Keep this in mind when "faking" other models. }}
 +
 
 +
{{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.}}
 +
 
 +
{{NOTE| According to the information found from the links above the authors suggest a change in the network card memory (ethtool -E ethX magic 0x2200 offset 0x8 value 0x12). However, this doesn't work on my Thinkpad X40. Further modifications were needed to eliminate the 1802 error. The value of the first register inside the memory of the PCI card should be modified to read:
 +
 
 +
<code>
 +
Offset: 0x0000
 +
Values: 02 a5 00 80 20 42 86 80 12 27 86 80 18 00 01 03
 +
</code>
 +
 
 +
one [http://fx.cz/sklad/intel/ source] suggest that one more value should be modified:
 +
 
 +
<code>
 +
offset 0xa8 value 0xf9
 +
</code>
 +
 
 +
although it might not be necessary.}}
 +
 
 +
=== Use another MiniPCI (express) slot ===
 +
 
 +
On models with multiple MiniPCI (express) slots, the BIOS checks only the “WiFi-slot” for unauthorized WiFi cards. A neighboring WWAN slot is allowed to hold such a card. But there might be a catch: the WWAN slot’s “disable radio” signal could be active, so that the card will refuse from using the radio. The operating system can see this condition: on Linux it is reported as “hard blocked” by rfkill. (This actually depends on the driver: “b43” does notice that the card refuses to switch it’s radio on and reports it via the rfkill interface.)
  
−
==Affected Models==
+
Combinations that work in the WWAN slot without further tweaking:
−
All series 3x, 4x, and 5x models (A, T, R, X)
+
* Lenovo Y530 / Intel 4965AGN
 +
* X61t (7762-94G) / Atheros 5008X scavenged from a MacBook Pro
  
−
==Affected Operating Systems==
+
On MiniPCI express(!) slots, pin 20 is used as the first “disable radio” signal, as implemented by common WiFi cards. Isolating pin 20 in the slot from the card will leave the signal dangling, which means “disable radio” is inactive: i.e. “radio on”. If necessary, the pin on the card can be taped over with film or painted over with nail polish to block electrical connection. Pin #20 is located on the underside of the miniPCI Express board, second pin from the notch, on the side with more pins. Here is [http://pinoutsguide.com/Slots/mini_pcie_pinout.shtml detailed MiniPCIe pinout]. Combinations reported to work this way:
−
All - problem is in the BIOS
+
* Thinkpad X61s / Intel Wifi link 4965agn
 +
* Thinkpad X61 / Intel 3945abg (bulk)
 +
* Thinkpad X200 / Intel 5300 and Broadcom 4312
 +
* Thinkpad T60p (widescreen) / Sierra MC8781
  
−
==Status==
+
Questions still open:
−
* Workarounds exist for most affected models.
+
* can the signal be deactivated otherwise? (WLAN-on-for-WWAN-slot)
−
* There was a report that none of these solutions work on the T43.
+
* do WWAN cards have such a signal? Is it on another pin (a “second disable radio” pin is defined for mPCIe since at least 2010)?
 +
** in case it’s the same signal, how to deactivate the WWAN kill signal? On the X200 the hardware switch doesn’t do that.
 +
* as the card (usually) drives an LED to reflect it’s state, can that signal be routed to the WWAN or WiFi LED?
  
−
==Solutions==
+
Taping over any Mini PCI-e pin is a delicate exercise in patience, the connectors are less than the width of most ball point pens. Transparent scotch type tape is easier to work with since it is possible to see where you're cutting.
−
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.

{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable. Proceed with caution!}}
 +
 
 +
{{NOTE|On the {{R32}}, {{T43}}, {{X41}}, {{X60}}, {{W500}}, {{X230}} and probably others, the BIOS hacks and the "no-1802" utility don't work.}}
 +
 
 +
See the table below for links to modified BIOS images with the whitelist disabled. Information on making this BIOS modification for newer ThinkPads can be found [http://www.endeer.cz/bios.tools/bios.html here].
 +
 
 +
Alternatively, you may can modify the 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].
  
−
{{NOTE|Any of the following solutions should suffice to make the wireless card useable.  You only need to perform one of them.}}
+
* You can try googling for your model number + "whitelist removal", there are lots of pre-hacked BIOSes out there.

* 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].
+
* 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.

{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}
 
  
−
* 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.

==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.

 +
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 description

The ThinkPad BIOS only allows to boot with an "authorized" adapter installed. If an unsupported card is detected, the BIOS prints a message on the screen and stops the system: 

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

The card's sub-vendor PCI-ID (which can be seen using lspci -v) is checked against a whitelist in the BIOS. IBM/Lenovo'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).1 or similar agencies in other countries.

Solutions

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

It may be possible to use the computer with the unauthorized card deactivated (but not removed). Press 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.

Modifying the card's ID

A safer and better method than modifying the BIOS is modifying the PCI-ID of the wlan card to match the authorized one:

  1. You'll risk the wireless card instead of the motherboard.
  2. Future BIOS updates will not create any problems.
  3. No problem with newer laptops with different BIOS; the only reqirement is to find an ID that is already listed in the BIOS, which can be easily achieved if the community maintaina a compatibility table.

The instructions are here (link down, 2011/05/14 - archive.org mirror here, second mirror 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 here or here or here (in German). The second one is much simpler because it provides an already patched and compiled ipw2200 driver required to do the job.

Instructions on how to unbrand an HP lt4132 (HP-rebranded Huawei ME906s WWAN module, compatible with some X1 Yoga and X1 Carbon models) can be found here

NOTE!
On Linux-based distributions, the driver is loaded based on the PCI-ID. Keep this in mind when "faking" other models.
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.
NOTE!
According to the information found from the links above the authors suggest a change in the network card memory (ethtool -E ethX magic 0x2200 offset 0x8 value 0x12). However, this doesn't work on my Thinkpad X40. Further modifications were needed to eliminate the 1802 error. The value of the first register inside the memory of the PCI card should be modified to read:

Offset: 0x0000 Values: 02 a5 00 80 20 42 86 80 12 27 86 80 18 00 01 03

one source suggest that one more value should be modified:

offset 0xa8 value 0xf9

although it might not be necessary.

Use another MiniPCI (express) slot

On models with multiple MiniPCI (express) slots, the BIOS checks only the “WiFi-slot” for unauthorized WiFi cards. A neighboring WWAN slot is allowed to hold such a card. But there might be a catch: the WWAN slot’s “disable radio” signal could be active, so that the card will refuse from using the radio. The operating system can see this condition: on Linux it is reported as “hard blocked” by rfkill. (This actually depends on the driver: “b43” does notice that the card refuses to switch it’s radio on and reports it via the rfkill interface.)

Combinations that work in the WWAN slot without further tweaking:

  • Lenovo Y530 / Intel 4965AGN
  • X61t (7762-94G) / Atheros 5008X scavenged from a MacBook Pro

On MiniPCI express(!) slots, pin 20 is used as the first “disable radio” signal, as implemented by common WiFi cards. Isolating pin 20 in the slot from the card will leave the signal dangling, which means “disable radio” is inactive: i.e. “radio on”. If necessary, the pin on the card can be taped over with film or painted over with nail polish to block electrical connection. Pin #20 is located on the underside of the miniPCI Express board, second pin from the notch, on the side with more pins. Here is detailed MiniPCIe pinout. Combinations reported to work this way:

  • Thinkpad X61s / Intel Wifi link 4965agn
  • Thinkpad X61 / Intel 3945abg (bulk)
  • Thinkpad X200 / Intel 5300 and Broadcom 4312
  • Thinkpad T60p (widescreen) / Sierra MC8781

Questions still open:

  • can the signal be deactivated otherwise? (WLAN-on-for-WWAN-slot)
  • do WWAN cards have such a signal? Is it on another pin (a “second disable radio” pin is defined for mPCIe since at least 2010)?
    • in case it’s the same signal, how to deactivate the WWAN kill signal? On the X200 the hardware switch doesn’t do that.
  • as the card (usually) drives an LED to reflect it’s state, can that signal be routed to the WWAN or WiFi LED?

Taping over any Mini PCI-e pin is a delicate exercise in patience, the connectors are less than the width of most ball point pens. Transparent scotch type tape is easier to work with since it is possible to see where you're cutting.

See the discussion page for more.

Modifying the BIOS

ATTENTION!
It is dangerous to mess with your BIOS, you can easily make your machine unbootable. Proceed with caution!
NOTE!
On the R32, T43, X41, X60, W500, X230 and probably others, the BIOS hacks and the "no-1802" utility don't work.

See the table below for links to modified BIOS images with the whitelist disabled. Information on making this BIOS modification for newer ThinkPads can be found here.

Alternatively, you may can modify the whitelist to include the PCI-ID of the card you wish to use. The complete instructions for this procedure are here.

  • You can try googling for your model number + "whitelist removal", there are lots of pre-hacked BIOSes out there.
  • You can use the DOS no-1802 utility, written by Tisheng Chen.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. 3

#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.

Pin Signal Description
11 LED1_GRNP WiFi active LED +
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:
MiniPCI Specification (PDF, 724KB)
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.

ATTENTION!
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.
