I wouldnt call it hacking. If you can find or backup the bios image for your motherboard, you can replace the microcode in it and reflash. Bios images are modular and the microcode is a replacable component.
- marcan_42 5y agoHacking BIOS images isn't always that easy. Often they are signed (EFI Capsules) and the standard update utility in the BIOS menu will reject modified versions. I had to use a convoluted flashing process to make a trivial patch to a BIOS a few years back for this reason.
- csdvrx 5y agoYou mean, SOIC clip + flashrom?
- marcan_42 5y agoThat usually works, yes (modulo Boot Guard and electrical issues), but we're getting into less accessible methods, aren't we :) In my case I managed to get it to work with some random vendor tools run from DOS, which bypassed the EFI flash subsystem. Definitely not a pleasant experience.
