1MB BIOS image for the Pegatron IPN73-BA motherboard, a board Pegatron produced for OEM desktop systems. The archive is small, about 536 KB compressed, and should contain the raw image for a 1MB flash chip.

Back up the original contents and confirm the chip capacity and board model before writing.
