BIOS image for an X79P desktop motherboard, version V1.0, sized for an 8MB flash chip and packed in a 2.36 MB RAR archive. The name gives no board maker, so match the X79P marking and V1.0 revision printed on the PCB before flashing. X79 boards of this kind usually carry the BIOS in an SPI chip that a CH341A-type programmer can rewrite. Save the original chip contents first and confirm the extracted image is exactly 8MB, because a file of the wrong size will not fit the chip.
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.
