BIOS firmware for the Quanta DAY0BCMB6D0 motherboard, revision D, with 0817D in the name, likely a board date or BIOS build code. The file comes as a 3.57 MB RAR archive with no brand given in the name, though Quanta made this board for HP. DA-prefixed codes are typical Quanta board identifiers printed on the PCB. Use it to rewrite a corrupted SPI flash with an external programmer, keep the original dump as a fallback, and confirm the image length suits the flash chip fitted.
