Firmware for the Toshiba C55t-B5109 laptop using the Compal LA-B301P motherboard, provided as a 4.92 MB ZIP. Compal is the ODM behind LA-prefixed board numbers, so the same board appears in other Toshiba C50 and C55 models. The dump is used to rewrite the BIOS flash on units with no display, boot loops or a failed update. Program it with a hardware programmer only after saving the existing contents, and confirm the board number and image size match the chip on your board.
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 @bios_laptop. Enginerys does not host this file.
