Gigabyte GA-945PL-S3P motherboard BIOS, version F3, apparently for PCB revision 6.6 judging by the name. The 512 KB size matches a 4 Mbit flash chip, and the .f3 extension follows Gigabyte's habit of naming BIOS files by version. The image can be flashed with Gigabyte's utility or written directly to the chip with a programmer to recover a board with a corrupted BIOS. Confirm the PCB revision printed on the board and back up the current chip before writing.
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 →
