BIOS archive for the HP All-in-One 20-c001la with Quanta board DAN91AMB6D0, revision D. Numbers in the DA…MB… form follow Quanta's ODM scheme, where the code after DA names the project and the last characters give the board revision. A technician writes such an image to the SPI flash when the system will not POST or the firmware is corrupted. Read and save the original chip first, check the image size against the flash capacity, and confirm revision D on the PCB.
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 @biosarchive. Enginerys does not host this file.
