Firmware image for the ASUS Sabertooth 990FX AMD desktop motherboard, board revision R2.0, with the name pointing to BIOS version 2901 and marked as tested and working. Inside the RAR should be a flash image suitable for writing straight to the board's SPI chip with an external programmer when USB BIOS Flashback or EZ Flash cannot recover it. Check that the revision printed on the PCB is 2.0, dump and keep the existing chip contents, and verify the file size equals the chip capacity before programming.
