BIOS for an Acer desktop using the H81H3-M4 motherboard, an Intel H81 board, supplied as a 3.67 MB ZIP. The name gives no version or flash size, so check the extracted image against the chip marking before programming. Technicians use this kind of dump to revive boards with corrupted firmware by writing the SPI chip with a CH341A or similar programmer. Read and keep the original contents first, since they hold the serial and system data. Confirm the board label on the PCB matches H81H3-M4 and the Acer variant.
