BIOS and KBEC keyboard controller firmware for board DAX12MB1AD0 revision D, also written as X12-D, packed in a 4.37 MB ZIP. The DA prefix with MB code follows Quanta numbering, so Quanta is the board maker. The set is useful for reviving a dead or looping board where both the system BIOS and EC image need restoring. Dump the existing chips with a programmer before writing anything, confirm the revision on the PCB, and make sure each image matches its chip size.
