I'm trying to figure out what is searched for and modified in order to fully disable the whitelist in Lenovo Sandy Bridge laptops such as the T420/T520/X220/W520. There are older BIOSes that work, but it would be nice to know how to modify current and possible future BIOSes for these platforms.
It's already possible, Oleh (who isn't well regarded here) managed to roll what I think is public knowledge to remove the whitelists in these laptops:

But I'm not really wanting all of these other modifications, I just want the whitelist disabled - and some idea of how to do it in the following:
T420 (1.49): https://pcsupport.lenovo.com/us/en/downloads/DS018785
T520 (1.46): https://pcsupport.lenovo.com/us/en/downloads/DS018810
X220 (1.43): https://pcsupport.lenovo.com/us/en/downloads/DS018805
W520 (1.43): https://pcsupport.lenovo.com/us/en/downloads/DS018884
The driver utilities above also have multiple BIOS images in them as well, for I presume different versions such as Intel/Nvidia GPUs, and so forth. Being able to know what to look for and "patch" would also allow all of these separate images to be modified as well.
My assumption is that by "whitelist removal," this means that the check is totally disabled allowing any ID for Wifi card to be installed, no need to add in specific card device IDs.
Thanks for your knowledge!
