BIOS archive for the Toshiba Satellite C50-B863 built on Compal board LA-B301P, packed as a 4.84 MB ZIP. The LA-prefix follows Compal numbering, marking Compal as the ODM that made the motherboard. Technicians use such a dump to reprogram the SPI flash when the notebook powers up without display, loops at boot or was bricked by a bad update. Use an external programmer, save the original chip contents first, and compare the board number on the PCB and the image size with the installed flash chip.
