BIOS firmware for the Toshiba Satellite U400 on the Quanta board DATE1MMB8E0. The 1.08 MB RAR archive should contain an image for reprogramming the system flash when the laptop powers on with no display or is stuck after a failed update. Quanta board codes follow the DA plus project code pattern and end with the revision, here E0. Match the code printed on your PCB, take a full backup of the original chip, and check that the image size suits the installed flash device.
