ASUS B75M-A revision 1.0 BIOS dump packed in a zip, prepared for a Winbond W25Q128 flash chip. That part is a 128 Mbit, or 16 MB, SPI NOR device, so the image inside should be exactly 16 MB for a clean write. Repairers use dumps like this to revive boards with corrupted firmware after a failed update or power loss. Select the W25Q128 in the programmer software, read and keep the original contents, then erase, write and verify. Matching the revision printed on the PCB helps avoid incompatible images.
