Toshiba Satellite A135 BIOS dump, labelled S2276 and main, meaning the main system BIOS image, 1.00 MB in size, matching an 8 Mbit flash part. Technicians use it to restore a corrupted BIOS or clear a lockout by writing the image with an external programmer. Make sure the flash chip on your board has the same capacity, since a size mismatch means the image will not fit. Read and archive the existing contents first, and check that the model sub-number on the label corresponds to the board you are repairing.
