Known-good BIOS for the ASUS SABERTOOTH 990FX desktop motherboard, an AMD 990FX chipset board, stored as a 4.54 MB RAR archive. The name only states that the image is OK and gives no version. Technicians use such a file when the board will not POST due to corrupt firmware, programming the flash chip off-board or in-circuit with a programmer. Verify the exact board revision, read and keep the original chip, and make sure the file size matches the chip before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
