Working BIOS for the HP Compaq CQ42 with AMD platform and discrete ATI graphics, Quanta board DA0AX2MB6E1 revision E, which the name says is fully tested. Supplied as a 1.13 MB ZIP archive. Quanta boards use the DAxxxxMBxxx pattern printed on the PCB, and the last character distinguishes versions, so confirm yours is DA0AX2MB6E1 and not a sibling. Flash it to the SPI chip with a programmer after reading and saving the original, and check the image size matches the chip 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.
