BIOS firmware for the Dell Precision M6500 mobile workstation, Quanta board DA0XM2MBAG1, revision G, stored in a RAR archive. Quanta motherboards use the DA0-prefixed numbering seen here, and the trailing letters reflect the PCB build. Use the dump to reflash the SPI BIOS chip when the system is bricked or the firmware is corrupted. Dell images may include service tag and other system data, so save the original chip contents first. Match the revision on the board and confirm the file size suits the flash chip.
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.
