BIOS for the ASUS M4A77TD desktop motherboard, revision 1.01G, an AMD socket AM3 board. The ZIP archive is about 690 KB, consistent with a 1 MB class BIOS image. Such a file is used to recover a board that fails POST after a corrupt update, either by programming the BIOS chip externally with a programmer or by swapping in a reflashed chip. Check the revision printed near the PCIe slots or on the PCB edge, read and keep the original chip contents, and ensure the image size matches the flash capacity.
