BIOS image for the Gigabyte GA-P55A-UD3P motherboard, revision 1.0, an Intel P55 chipset board for LGA1156 processors, shipped as a RAR archive of roughly 1.61 MB. Gigabyte boards of this era typically carry dual BIOS chips, and a clean image can restore either one with an SPI programmer. Always read and back up the existing chip contents, check that the image fits the chip capacity, and confirm the revision printed on the PCB matches 1.0 before writing.
