BIOS image archive for the Gigabyte GA-P55-USB3L desktop motherboard, board revision 2.0, size 1.48 MB in RAR form. The file name states no BIOS version, so check the contents after extracting. Gigabyte boards of this generation often carry dual BIOS chips, and a clean dump helps when both copies are corrupted and the board stays dark. Write it with an SPI programmer after saving the original contents. Because revision 1.0 and 2.0 boards differ, confirm the revision silkscreened on the PCB first.
