Gigabyte GA-P55A-UD3 BIOS firmware for PCB revision 2.0, supplied as a RAR archive of about 1.57 MB. It is intended for restoring a damaged BIOS chip on this desktop board when it no longer posts and the backup routine fails. Write it with an SPI programmer or the board's own update tool. Revisions of Gigabyte boards may use different firmware, so read the revision silkscreen on the PCB, save the original chip contents before writing, and ensure the image size matches the chip.
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.
