Working firmware set for the Toshiba Satellite L750 C18S on Quanta board DABLBDMB8E0, revision E. The name lists three chip positions, U21, U9 for the EC and U8, so the 1.68 MB archive should contain separate images for the BIOS and embedded controller. Quanta boards use the DA-prefixed numbering seen here. Match each file to its chip by location and size, back up every chip before writing, and confirm the PCB shows revision E before flashing with an SPI programmer.
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.
