BIOS for a Quanta-made board numbered DAZAUIMB8C0 at revision C, for the variant with Intel integrated graphics and no discrete GPU. The name says the image was tested and fully working. Quanta board numbers in the DA format are printed on the PCB silkscreen, so check both the board number and the revision before flashing. Writing the wrong graphics variant may leave the board without display output. Back up the original SPI chip with a programmer first, then write and verify the image.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biositechyangiyer. Enginerys does not host this file.
