I got an Intel 6230 Wireless card today, replaced the factory card, and booted my computer to be greeted with a message saying "Unauthorized network card". I removed it, cleared the supervisor password on my BIOS, and rebooted with it plugged in. Same message.
Google time! Found that Lenovo does this to a lot of their laptops, and whitelists, not blacklists, a few cards. Can somebody please explain if it's possible to override it, or why this "feature" is here in the first place? To protect from... malicious wireless cards?

Lenovo, as well as most of the major players match the card with the antennas to comply with FCC regulations regarding interference.
The card has to be a Lenovo branded card, a generic one won't work, (as you found out).
Your machine will take an Intel 5300 as long as you have the three antennas for it. Again, it has to be a Lenovo branded card.

Sometimes you can tape off pin 20 on the card and get the bios to accept it.
Most of the time that doesn't work.
