BIOS dump archive for the HP 15-ay000ur, built on Compal board LA-D702P with the project code BDL50. Compal boards are identified by the LA-xxxxP number printed on the PCB, so confirm it matches before flashing. The 7.37 MB RAR opens with 7-Zip or WinRAR and may contain the main BIOS and possibly EC firmware. Such images are written to the SPI chip with a hardware programmer to recover a dead or bricked board. Read and save the original chip contents first, and check the image size against the chip.
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.
