BIOS archive for the Toshiba Satellite L735 notebook, made on a Quanta motherboard DABU5DMB8E0, revision E. Quanta numbers follow the DA plus project code plus MB pattern, and the BU5 project code with revision letter are silkscreened on the PCB. The 1.57 MB file is meant to be written to the SPI flash with a programmer to cure dead boards, boot loops or a corrupted firmware region. Check that board number and revision on your unit match before use, and save a copy of the original chip contents first.
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 @bioshub. Enginerys does not host this file.
