A 16 MB BIOS image for the GH51M platform on the Compal LA-K862P board, marked as working. No revision is given in the name, so read the revision from the PCB and compare it with any notes inside the 17.7 MB RAR archive. The dump is sized for a 16 MB (128 Mbit) SPI chip and can be written with a programmer such as the CH341A or RT809H. LA-xxxxP is Compal's numbering scheme. Back up the existing firmware before you flash anything.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
