Backup of the BIOS from an ASUS K42JR mainboard, revision 4.1, stored as a 1.60 MB RAR. Being a read from a working board, it can be programmed back onto the SPI flash to recover a unit with corrupted firmware. Such backups may contain the original machine's serial and identity data, which may need adjusting afterwards. Use an external programmer, read and keep your own chip contents before writing, verify the board revision on the PCB is 4.1 and make sure the image size matches the flash.
