BIOS dump for the Quanta board DAG3HEMBCD0, revision D, sized for a 16 MB SPI flash chip according to the name. Quanta uses the DA-prefixed numbering for boards it produces for HP, Acer, Dell and other brands. The 14.4 MB RAR should be extracted and its image size checked against the chip before writing with a CH341A, RT809 or similar programmer. Dump and keep the original chip contents first, and confirm the board number and REV D marking on the PCB match.
