BIOS image archive for a Foxconn H55M-S desktop motherboard, catalogued under the ECS brand, with A21F1P05 appearing to be the board or firmware identifier and an 8 MB image size stated. The H55M-S name points to an Intel H55 chipset board. Technicians use such a dump to recover a board that will not POST after a failed update by writing it to the SPI flash with a programmer. Read and save the original chip contents first, confirm the chip is 8 MB, and match the board model printed on the PCB before flashing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
