Using non-Lenovo Network cards

If you get 

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

on boot, that means your BIOS does not include that specific card in its whitelist. The only option is either coreboot or a custom BIOS with the whitelist "disabled".

Such a bios can be found at this forum post at mydigitallife.info.

You can either use Windows to flash, or a DOS boot disk with phlash16.exe and the 02C2100.ROM from the forum post's rar like I did. To do it this way, first upgrade the BIOS to the latest version from Lenovo. Then, rename "02C2100.ROM" to "BIOS.WPH", save it to your DOS boot disk and run phlash16.exe.

gollark: Oh, hey, a 2G gold in it.
gollark: Oh, the random ash dragons.
gollark: What random ash dragons?
gollark: That's quite simple. The scroll thing would be yet another bit of workflow to program.
