It has whitelist for wireless cards ? That's just evil

Lenovo has whitelists for both wifi and cell cards. It's highly annoying.

A decade ago, I had a Lenovo Yoga 2. The Wi-Fi card it came with only supported 802.11g, or something old and outdated at the time. I learned about the whitelist the hard way when I bought a decently (then) up-to-date wifi card to upgrade, and the computer refused to boot.

But! I refuse to let a computer tell me no... So, after many many (too many) hours of reading forums, dumping firmware, flipping bits, and pushing firmware, I got the stupid card to work. And of course I took no notes, so if I had to do it again, I'd be starting from scratch.

Supposedly it's for FCC compliance. Makes perfect sense if you believe it, but I'm not super convinced.
