BIOS archive for the ASUS Sabertooth 990FX desktop motherboard, revision 1.0, with a 4 MB image per the name, matching a 32 Mbit flash chip. The RAR is about 2.3 MB compressed. The 990FX is an AMD chipset for AM3+ processors. Use the image to reprogram the BIOS chip with an external programmer when the board fails to post after a corrupted flash. Back up the existing chip before writing, and confirm the board revision and chip size so the image fits correctly.
