Toshiba Satellite L755 BIOS, part number PSK2YE, for Quanta mainboard DABLDDMB8D0, supplied as a 1.55 MB RAR archive. The PSK code identifies a specific regional configuration of the L755. Quanta prints the DA-series number on the PCB, and it should match before you program anything. Unpack the image, verify its size against the flash chip, and save a full read of the original chip with an SPI programmer first so the board can be returned to its previous state.
