BIOS image for a Toshiba laptop mainboard with Quanta board number DABL5SMB6E0, revision E, given as a 1MB dump. Quanta uses DA-prefixed numbers on its PCBs, and the BL5S project code is embedded in this one. A 1MB size points to a small SPI chip, so confirm the chip capacity before programming. Compare the number and revision on the board, back up the existing chip with a programmer, then write this file to recover a board that does not boot or shows no display after a corrupted BIOS.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
