T42 and Intel WM3B2200BG Incompatibility Problem

[Glycerin]

I recently got a T42 motherboard to replace a T40 motherboard. Neither had a WiFi card, so I bought an Intel WM3B2200BG 39T0077 Wireless card for it but got the 1802 error. I ran the BIOS patch to make it work, but I thought it was "certified" by IBM? Which WiFi cards are compatible with the T42 series? Thanks!

According to the hardware maintenance manual, this card is for the T43.

The T42 also has 2200BG as an option (I know because my T42 has one), but the FRUs are different: 93P3483 and 93P3485.

I don't know if the cards are somehow different (different revision maybe?). Sometimes Lenovo has different FRUs for the exact same part.

Another option is that the BIOS for the T42 board needs to be updated.
