I wanted to install a third-party Atheros wireless card into my uncle's old T43. Problem is I hit 1802 error and I can't cure it!

I updated to latest BIOS (1.22) and Embedded Controller (1.05) on the system. Then I tried 3 different reincarnations of no-1802.com I found on the web including a linux live CD and a couple of executables. They all seem to work fine and load with no errors returned but when I reinstall the card and restart the PC, the message persists. Am I missing something here?

P.S. Machine is type 1871. It's a regular 14in T43 with Intel video card.

"No-1802" hack doesn't work on T43, R52 or any of the later models.

You need a modded BIOS in order to use a non-whitelisted card.

Wow, didn't know that. Where do I get such a BIOS?

Scroll down to: Use unofficial modified BIOS
There are 2 versions for the T43, one for TYPE 18xx (Intel) and TYPE 26xx (ATI).
Those BIOSes also get rid of that pesky Hard Disk Error 2010.
Highly recommended BIOS updates!

Got it! Thanks.
