BIOS dump for the PLF/CSF motherboard in the 45W UMA and DSC versions, revision 2.1, marked tested OK and stored in a 2.74 MB RAR. The name does not state the laptop brand, though the PLF/CSF code with these variants matches boards known from Toshiba Satellite C850 and L850 machines. Flash it with an SPI programmer to recover corrupted firmware or a board that will not post. Read and keep a backup of the original chip first, and confirm the dump size matches the flash chip.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
