BIOS file for the Sabertooth 990FX desktop motherboard, revision 1.01, compressed as a 2.29 MB RAR. The 990FX is an AMD chipset for AM3+ processors, and this board is sold under the ASUS TUF line. A dump like this is used to restore a board that no longer posts after a failed update by programming its BIOS chip externally. Make sure the PCB revision printed on the board matches, back up whatever is on the chip before writing, and verify the image size against the chip capacity.
