BIOS dump for the Toshiba Satellite L55DT, built on Quanta board DA0BL0MB8F0, read from a GD25Q64 flash chip. The GD25Q64 is a GigaDevice 64 Mbit part holding 8 MB, so the image should be exactly that size. The DT suffix marks an AMD touchscreen variant of the L55 line. Quanta's DA0 project code printed on the PCB should match before flashing. Use an SPI programmer to write the chip after saving its current contents, which helps when a corrupted BIOS leaves the machine without display.
