BIOS files for the HP 15-bs742TX laptop, board DKL50 with Compal number LA-E802P, revision 1.0. The LA- prefix is the Compal numbering pattern, and DKL50 is the matching project code. The archive is fairly large at 21.6 MB, so it may hold several images or tools rather than one dump. Use it to reflash the SPI chip with a programmer when the machine has no display or cycles power. Confirm the PCB label shows LA-E802P rev 1.0 and back up the original chip before writing.
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.
