Working BIOS for a Toshiba laptop on Quanta board DATE1MMB8E0, revision E, packed into a 3.65 MB RAR archive. The name states a 2MB flash image and marks it as fully working. Quanta DA0-style numbers encode the project code and board revision, so compare both against the PCB. Read the original SPI chip with a programmer and save it, make sure the chip is 2MB to match the image, then flash and verify to recover a board with corrupted firmware.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
