Firmware dump for Quanta board DAAX3MB16A1, revision A, labelled 1MB, packed into an 877 KB RAR archive. The 1 MB size suggests an 8 Mbit flash, which on this design may be a separate EC or keyboard-controller chip rather than the main BIOS, though the name does not say which. Identify the chip and its capacity on the board before writing, since an image that does not match the device will not fit. Read and back up the existing contents with a programmer first, and check the PCB number and revision match..
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.
