Theoretically we should be able to use a VGA[3] cable and expose the wires of pins 12(SDA) and 15(SCL) to access the bus. I can test that proof of concept if I complete the project earlier than expected.

Any particular mainboard might not be so important as long as the SMBus can be accessed somewhere; possibly a cellphone repair store can help solder the three SMBus wires to a small connector for the purpose of the project. But it would be great to also consider what the user story is for people who want to use this on other mainboards. Ideally it shouldn't be neccessary to buy a niche product like a RAM breakout adapter; it would be great to also explore more ways to access the SMBus signals, e.g. PCI Express optionally has SMBus, smart batteries have it, etc. Kind regards //Peter ___ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-le...@coreboot.org
