BIOS dump for the Toshiba Portege X20W-D convertible, reported as working, in a RAR archive of about 5.37 MB. The name gives no BIOS version, board number or flash chip type, so identify the chip on the board and check that the image size matches it before programming. A dump like this is used to restore a laptop with corrupted firmware by writing the SPI chip with an external programmer. Read and save the existing chip contents first in case you need to keep unit-specific data or roll back.
