ASUS P9X79 Deluxe BIOS, version 4801, delivered in a 4.38 MB RAR archive. The board uses Intel's X79 chipset for LGA2011 processors. A technician can use this image to reprogram the SPI flash with an external programmer when the board fails to post, or to update through ASUS tools after renaming the file appropriately. Before writing, back up the original chip so the MAC address and serial data can be restored, and confirm that the file size matches the flash chip capacity on the board.
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.
