Working BIOS for an HP notebook on Quanta board DA0AT5MB8E0, revision E, archived as RAR at about 724 KB. Quanta uses the DA0xxxMBxx0 pattern for its motherboards, with the model code embedded in the middle. The small size suggests a compact flash image, so compare it with the capacity of the chip fitted. Flash it with an SPI programmer to recover a board with no boot or a corrupted firmware. Read and keep the original contents before writing anything.
