BIOS and KBEC firmware pair for an HP laptop using Compal board LA-D703P revision 1.0, with the date 2016-03-02 printed in its name. Packed in a 4.70 MB zip. KBEC refers to keyboard and embedded controller firmware, which handles power-on, battery charging and the keyboard matrix. Compal uses LA-numbers across many brands. Confirm the PCB number and revision, dump both chips before flashing, and make sure the image size of each file matches its chip so the system and EC images go to the right devices.
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.
