M5A99X-EVO rev 1.01

BIOS .zip 2.34 MB Shared

BIOS package for the ASUS M5A99X EVO, an AMD 990X socket AM3+ board, marked revision 1.01 in the name. At about 2.3 MB it likely contains a full UEFI image or the vendor CAP file, which usually needs adjustment before a programmer can write it directly. Verify the PCB revision near the slots, and dump the original chip first to keep the MAC address and board-specific data. Use the image to recover a board that powers on without POST after a failed update.
