BIOS firmware package for an HP Compaq Presario desktop identified by the product code 21N001AR, packed as a 2.79 MB RAR archive. The name gives no board number, revision or flash chip size, so confirm the motherboard model inside the case before using it. Technicians use such dumps to recover a unit that will not post after a failed update or a corrupted SPI chip. Read and save the original chip contents with a programmer first, and make sure the image size matches the capacity of the flash chip fitted on the board.
