BIOS archive for the HP ProDesk 400 G1 small form factor desktop. The name lists Arondite, which is likely the system board code name, and revision A. The 4.15 MB RAR contains firmware for reprogramming the SPI flash on boards that fail to POST or show corrupted firmware. HP business desktops store serial, product ID and other system data in the BIOS region, so save a copy of the original chip with a programmer before writing. Confirm the board revision and chip capacity first.
