BIOS firmware archive for the Toshiba Satellite L750 built on Quanta board DABLBMB28A0, labelled for the Core i3 version fitted with a discrete GPU. The DA-prefixed number follows Quanta's numbering, so Quanta is the board maker behind this Toshiba. Unpack the 1.67 MB zip and write the image to the SPI flash with a programmer such as a CH341A. Read and save the original chip contents first, and confirm that the PCB carries the same board number and a dedicated graphics chip before flashing.
