Firmware archive for Quanta board DA0AX1MB6H0 at revision H, with no laptop brand or model named. The DA0 prefix belongs to Quanta's numbering scheme, used on boards it built for several notebook brands. The ZIP of about 1.7 MB probably holds a BIOS image for programming the SPI flash. Check that the board number and revision letter on the PCB match exactly, back up the existing chip before writing, and confirm the image size fits the installed flash chip.
