BIOS image for the Gigabyte GA-B150M-EVO, revision 1.0, compressed into a 5.23 MB RAR archive. The name specifies an 8 MB flash, so the extracted binary should equal 8 MB and suit a 64 Mbit SPI chip. Technicians use such a dump to recover a board after a failed update or corrupt firmware by writing it directly with an external programmer and clip. Read and save the existing chip first, compare the board revision printed on the PCB, and verify the write afterwards. Gigabyte boards may carry dual BIOS chips, so identify which one is being programmed.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
