Backup of the BIOS for a Gigabyte P31S3G desktop motherboard, delivered as a 269 KB RAR archive. The name gives no revision, version or chip size, so check the extracted image against the flash device on the board. Such a backup is used to recover a board with corrupted firmware by programming the BIOS chip directly with an external programmer or clip. Read and keep the current contents of the chip first, and verify the PCB revision printed near the slots matches before writing anything.
