BIOS dump for the Toshiba Satellite L740 laptop with Quanta motherboard DAT0E4MB6D0, revision D. The DA...MB code and trailing revision letter follow Quanta's pattern, the ODM behind this board. Stored as a 1.77 MB RAR, the image is for programming the BIOS flash chip directly when a machine has a corrupted firmware or no POST. Match the full code and revision on the PCB, read and keep the existing chip contents, and confirm the size fits the chip.
