Known-good BIOS for the Quanta-numbered DAH97MMBAC0 board, revision C, HF version, packed into an 8.92 MB RAR file. Unlike a related upload, no processor is named, so check which CPU variant your board carries before choosing between images. The dump is intended for writing to the SPI flash chip with an external programmer when firmware corruption causes no-boot or no-power faults. Save a full read of the original chip first, confirm the revision letter on the PCB matches, and make sure the image size matches the flash capacity.
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.
