Original BIOS dump labelled only as Toshiba, with no model, board number or version in the name. It is a 4.00 MB binary, matching a 32 Mbit SPI flash chip. Without identifying details its origin cannot be confirmed, so it is best used as a reference or compared against a read of your own chip rather than flashed blindly. If you do program it, back up the existing contents first, confirm the board matches the source machine, and check that the chip capacity equals the image size.
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 @bios_laptop. 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 →
