BIOS archive for the HP 15-AS056 laptop on Compal board LA-B972P. Compal uses the LA-xxxxP pattern, printed on the motherboard together with a revision number, which should be checked before flashing. The RAR is 4.23 MB and may contain the image plus notes. Read the original chip first with an SPI programmer so serial and service data can be recovered, and confirm the dump length matches the flash chip size or it will not program correctly.
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.
