BIOS package for the Gigabyte GA-H81M-S desktop motherboard, naming an MX25L3205 flash chip and an IT8620E Super I/O controller. The MX25L3205 is a 32 Mbit (4 MB) SPI part, so the image should match that capacity. Technicians use such a dump to revive a board after a failed update by writing the chip directly with a programmer and a clip or socket. Read the original chip first, check its marking, and confirm the board revision on the PCB matches the source board.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
