Firmware package for the HP Compaq CD7900 small form factor desktop, referring to the MARS board at revision B with HP part number 462431-001, plus a version tag in the name. Delivered as a 2.02 MB RAR archive. Technicians use such a BIOS image to restore a business desktop whose flash is corrupted, usually by writing the chip with an SPI programmer or by HP recovery methods. Check that the spare part number on the motherboard matches 462431-001, back up the existing chip, and verify the image size against the flash chip.
