BIOS image for the HP Compaq dc7900 business desktop, with the name indicating firmware family 7G1 and version 01.23, archived as a 1.86 MB RAR. It serves to restore boot on a machine whose flash is corrupted after a bad update or failing chip. The dump is written to the motherboard SPI flash with an external programmer or recovered through HP's tools if the image is a proper update package. Back up the original contents, verify the chip capacity matches the image size, and note that system serial data may need restoring afterwards.
