Hello @68k-dude , I have a Supermicro H11DSi rev. 2.0 motherboard that I use with Epyc 7xx2 generation processors. I have attemped to add the RebarDxe FFS to the V2.8 BIOS (available here) using UEFITool 0.28.0 and then flashing the BIOS using AFU via EFI Shell - using the flash.nsh EFI Shell script that is provided with the stock BIOS but I always get this error when trying to flash it:
Error 18 - Secure Flash Rom Verify fail.
Is there some signature check before the BIOS file is flashed? Is there a way to bypass it?
I’ve seen some success stories with H11DSi-NT but I am stuck here.
Thanks
