Toshiba BIOS file for the board marked CA10BM, revision 2.1, packed in a 3.30 MB zip archive. The name does not state the laptop model, so identify your board by the code printed on the PCB before using it. A firmware dump like this is written to the SPI flash with a hardware programmer to recover from corruption or a failed update. Open the archive to see the image file, keep a backup of the original chip, and check that the image size matches the flash chip capacity.
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.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
