How do I flash the firmware for the ite5570vg 128? Thank you for your help.

Hello, my issue concerns an all-in-one desktop PC motherboard—not a laptop motherboard—which has developed a short circuit. The component labeled "IT5570VG-128" burned out; I have replaced it, but the ROM needs to be programmed. Additionally, I haven't been able to locate a replacement keyboard connector, so I haven't been able to complete the repair. Thank you for your responses; I am attaching the relevant photos.
