BIOS .bin 9.26 MB Shared

ASUS A85XM-A desktop motherboard firmware, version 0404 according to the name, delivered as a 9.26 MB file. That size is larger than a standard 8 MB SPI chip, which suggests a vendor update capsule with a header rather than a raw dump; such files normally need the header stripped or must be flashed through the board tools instead of a programmer. Verify the chip capacity and the exact board model before writing anything, and save the current chip contents so you can roll back if the result does not boot.
