Firmware package for the Toshiba U400 notebook, tied to board code DATE1MMB80 according to the file name, supplied as a 2.25 MB ZIP archive. The DA-prefixed code resembles Quanta motherboard numbering, which Toshiba used widely in that era. A dump like this is used to restore a dead or bricked board by reprogramming the SPI BIOS chip with an external programmer. Read and save the original chip contents before writing, and check that the board marking and flash size match the image inside.
