Firmware package for the Acer Predator PH317-51 laptop, board code C5PRH, containing both the BIOS image and the keyboard/embedded controller (KBEC) firmware, in a 4.87 MB RAR. Having the EC file alongside the BIOS helps when a unit is dead, will not charge or fails to power on after a corrupted EC chip. Flash the images with a suitable programmer onto the correct SPI chips, always backing up the original first. Confirm the board code on the PCB matches C5PRH and that each image fits its target flash size.
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.
