Maybe I'm dense, but could someone not just upload the adapted F22g BIOS(offset 0x4EF = 0) for the rest of the users of this mb(like me)?

0x4EF

sorry, my mistake

@comed78
did you use new modified GRUB Shell or other the first one? How did you make your usb, which OS you use: windows, Linux or Mac...etc?

I'll give it a shot, but I'm thinking it will fail checksum (you modify the bios stored on your motherboard once it's already running)
See down the thread for my modified bios.

Here's my BIOS image.

Maybe it'll upload no issue, or maybe it will fail checksum, hard to tell (aka I haven't tried reloading my own BIOS image)

thanks canyondust,
is there a risk, for example if it will fail on checksum, whether it will possible to put back the original bios?

I think it will just not let you load it.

I just checked the image I've saved, and it's reverted the varstore value to 0x1. I'll have to load the grubshell and see if it's true or not, but I'll have to do that later. Work and such...

Checked with VerifyMsrE2 and it’s reporting still unlocked so who knows

I just updated with your bios, but I really didn't see any different
