BIOS image for the Dell Vostro 1000 built on the Quanta FX2 platform at revision D, delivered as a 566 KB 7z archive. Quanta is the ODM of this motherboard, and its project code FX2 should appear in the board number on the PCB. Older images like this are small and usually written to a parallel or SPI flash with a universal programmer. Check that your board revision is D, read the existing chip before overwriting it, and make sure the image size matches the chip capacity, otherwise it will not fit.
