RAR archive of BIOS firmware for an NEC Versa Pro notebook built on the Compal LA-C423P motherboard. The name gives no revision, chip type or file list, so extract the 11.5 MB archive and inspect its contents before choosing an image. Compal uses the LA-xxxxP pattern for its laptop boards, and the code is silkscreened on the PCB. Check that the board revision matches and that the image size equals the flash chip capacity. Read and save the original dump with your programmer before reflashing.
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 @LCS_Biossolutions. Enginerys does not host this file.
