Zipped BIOS binary for the Fujitsu Esprimo P720 desktop, motherboard D3221-A1. Fujitsu marks its boards with D3xxx codes followed by a revision suffix, which should be checked on the PCB before flashing. Use a hardware programmer to write the image to the SPI flash when the PC fails to POST or a BIOS update went wrong. Unzip it first, confirm the file size equals the flash chip capacity, and keep a read of the original chip in case it holds system-specific data.
