RAR archive holding the BIOS together with the EC (embedded controller) firmware for an HP Envy notebook on the Compal LA-9511P board, revision 1.0. Having both images is useful when a board will not power on or shows no display after a failed update, since a corrupt EC can stop the machine just like a bad BIOS. Compal LA-series numbers are printed on the mainboard, so match board and revision first. Back up the existing chips with a programmer before writing, and check that each file size matches its target 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.
