Toshiba notebook BIOS identified by the part number PSAG8U-04001W, the factory model code printed on the laptop label, in a small 808 KB ZIP archive. The name does not give a BIOS version or flash chip type, so open the archive to see whether it holds a raw dump or a Toshiba update utility. Matching the PSAG8U model code on the unit label is the first check. For programmer recovery, back up the current chip and confirm the image size equals the flash capacity before writing.
