It depends on the white list in your BIOS. It is possible that all IBM T42
laptops accept this particular card with an atheros chipset in addition to
the one in your laptop. This appears to be a card that would work in your
system and it would also be compatible with Trisquel.
Notice that this card might not work out of the box:
"You may also need to update your bios if you get a 802.11 error"
The actual message you would get is probably:
"1802: Unauthorized network card is plugged in - Power off and remove the
miniPCI network card."
In that case you can attempt to update the BIOS. It is potentially dangerous
to do this. You can damage your system if you make a mistake. If you get the
BIOS image from IBM/Lenovo for this system it is less likely to be a problem
than if you were to try hacking the BIOS yourself and getting a card to work
that way.
We actually just destroyed 3-4 motherboards recently. I'm still trying to
figure out where the problem is. Everything matches perfectly from what I can
see and there is no hacking going on with the 4th ruined board. There is a
possibility to recover in some instances although it can be tricky and may
not work in all instances. You probably don't have the recovery feature in
the T42.
