BIOS dump for the Toshiba Satellite E45W-C4200X laptop, distributed as a 3.60 MB RAR archive. The name does not give a board number, flash chip or firmware version, so check the archive contents and the image size against the SPI chip on your board. Such a dump is reprogrammed with an external programmer to revive a board that fails to boot after a bad update or chip corruption. Read and archive the original chip contents before erasing, and compare the mainboard identification printed on the PCB with the source of this image.
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.
