BIOS dump for the HP G42-230US, AMD CPU version, on Quanta board DA0LX8MB6D1, revision D, in a 1.12 MB RAR. The DA0...MB code with a trailing revision character is Quanta's motherboard numbering. The file is meant to be programmed onto the SPI flash using an external programmer when the laptop powers on with no display. Since Intel and AMD versions of this model use different boards and firmware, confirm the AMD board and revision D before writing, and keep a backup of the original.
