BIOS archive for the HP 15-bS002NE laptop on Compal board LA-E791P revision 2.0, with the CSL50/CSL52 codes from the board label also given in the name. The 16.7 MB RAR likely holds the SPI image or images needed to restore a board with damaged firmware. Compal numbers its mainboards in the LA-xxxxP format, and the revision matters, since a Rev 1.0 board may not behave the same with this image. Dump and save the existing flash first, then confirm the image size equals the chip capacity before writing.
