ROM image of the ASUS P8H61-PLUS desktop motherboard BIOS, version 4306 according to the name. The 4.00 MB file matches a 32 Mbit SPI flash part typical for this Intel H61 board. It can serve to recover a board that will not post after a failed update, written with an external programmer, or through ASUS tools if it is a capsule file. Compare the board revision printed on the PCB with your unit and save a dump of the original chip before replacing its contents with this image.
