BIOS package for the Toshiba M750 series, version 1.30, packed in a 466 KB RAR. The name gives neither a board number nor the file type inside, which may be a raw chip image or an update package from the manufacturer. A raw image is written to the flash chip with an external programmer to revive a board after a corrupted update. Check the contents first, and if you are programming the chip, back up the original and confirm that the image size matches.
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.
