BIOS dump for a Toshiba laptop, identified in the name only by the codes FASRSY2 and A3809A, which likely refer to the board or a part marking but are not explained. The RAR archive is 4.05 MB. Match these codes against the markings on your own motherboard before using it. A dump like this is written to the SPI flash chip with a programmer to repair corrupted firmware. Read and save the original chip first, and confirm that the image size equals the chip capacity, since a mismatched image will not fit.
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.
