BIOS file for the ASUS P8H77-M desktop motherboard, PCB revision 1.04, an Intel H77 chipset micro-ATX board. The ZIP archive is roughly 4.31 MB. Repair technicians use such an image to reprogram the SPI flash with a CH341A or similar programmer when the board is bricked or stuck without video after an interrupted update. Confirm the revision silkscreened on the PCB, dump and save the existing chip first to keep MAC and serial data, and verify the image size matches the installed flash chip.
