BIOS dump for the Toshiba Satellite L750 on Quanta BLBD board DABLBDMB8E0, revision E, packed as a 1.63 MB rar. It is intended for reflashing the motherboard SPI chip with an external programmer when the original firmware is damaged. The DA-prefixed code follows Quanta numbering and is printed on the PCB along with the revision, so verify both match. Always read the original chip and keep that copy before erasing, and check that the dump size equals the chip capacity, as a mismatched image will not fit.
