BIOS file for the Toshiba Satellite L450D on the Compal LA-5831P motherboard, in a compact 789 KB ZIP archive. Compal marks its boards with LA-numbers followed by P, and the same number can appear in several laptop brands. Unpack the archive and write the image to the SPI flash with a hardware programmer if the machine will not POST after a failed update. Compare the board marking first, save a dump of the original chip, and confirm the image size equals the chip capacity before programming.
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 @biosarchive. Enginerys does not host this file.
