I installed a GPU (GTX 670) in my ML110 G7 and that worked fine until I updated the BIOS to version J01. After updating the BIOS, the system powers on and enters the "Illegal Opcode" warning screen. I can't even access the BIOS in this state. Removal of the GPU or resetting the NVRAM allows the system to continue to the BIOS, but to boot Windows, I need the machine in AHCI mode, and enabling AHCI mode causes the Illegal Opcode error screen again. Keeping the machine in legacy SATA mode allows it to be used with the GPU installed and boot to a Windows installer, so the issue seems to be with the BIOS and configuration and not with the GPU itself.
Is there any way I can solve this and boot normally into Windows?
Sorry if this is the wrong board, I couldn't find a "servers" board.
