Main BIOS dump for the HP 15-BS525UR notebook, built on the Compal LA-E791P motherboard at revision 2.0, in a 5.47 MB ZIP archive. The MAIN label suggests the primary system flash image rather than a separate EC or other chip. Compal boards show the LA code and revision on the PCB, and both should be verified. Use a CH341A or similar programmer to write it to the SPI chip when repairing a no-boot fault. Read and preserve the original chip contents first, and make sure the file size fits the flash.
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.
