BIOS for the Gigabyte GA-945P-S3 at PCB revision 3.3, a late version of this Intel 945P desktop board, packed in a 695 KB archive. Gigabyte ties BIOS files to hardware revision, and an image for rev 1.0 or 2.0 may not suit this one, so verify the marking on the PCB. Use the file to restore a board that will not post because of corrupted firmware, either through the dual BIOS mechanism or by programming the chip directly. Read out the existing contents before writing so nothing is lost.
