Hi,
I'm trying to work with some HP machines. I disassembled these machines and saw they the EC chip SMSC KBC1126-NU. I read the backup firmware and can see strings like `8051 RESET`, and I found if I modify certain part of the firmware, the machine will fail to power with some LEDs blinking, so I know the EC firmware is in the BIOS chip, and it's an 8051 program.
I searched about this chip, and some people say the EC chip also contains program. I can't find anything about this chip, and coreboot wiki has KBC1122 and I only found a 5-page product review on the Internet. I don't know if there's anyone know about this EC. I want to know about: - Where is the entry point of the EC firmware in the BIOS chip - How this EC chip does the power management and keyboard control
Thanks, Iru
