BIOS and EC firmware for the EH50F project on Compal board LA-H431P, packed in a 5.89 MB RAR. LA-prefixed numbers follow Compal's notebook board naming, and EH50F is the project code. The main image goes into the BIOS SPI flash, while the EC file drives power control, battery charging and keyboard functions. Write them with a hardware programmer only after backing up the original chips, and make sure LA-H431P on your PCB matches and the image sizes fit the installed flash.
