Working BIOS and keyboard EC firmware for a Toshiba laptop on motherboard DA0BLMMB6E0, revision E, sized for a 4 MB flash chip. The DA0-style code is the Quanta numbering scheme, so Quanta is the ODM for this board. Having both the system BIOS and the KBC/EC image lets a technician restore a board whose controller firmware is damaged, which often shows as no power or a dead keyboard. Write each part to its proper chip with a programmer, keep backups of the originals and check that revision E is printed on the PCB.
