BIOS dump for the Acer TravelMate P446 on Quanta board DA0Z8CMB8D0. Quanta uses the DA0 prefix followed by the project code and the MB marking; the final characters show the PCB revision, so compare them with your board. The 3.89 MB ZIP suits a modern SPI flash and is written with a programmer such as a CH341A when the firmware is corrupted. Back up the original chip first, since it can carry the serial number, MAC and Windows key data.
