This is my first email to this mailing list. I've joined because I've a little question related to the BIOS superio initialization process and I would like to ask to the masters.
We specialize in coreboot related questions, so it's unlikely we can help you with a BIOS problem unless you want to replace that BIOS with coreboot.
I'm developing a little hardware module with a w83627hf superio module. This hardware is attached to a com express module. I've found that my hardware is not always initialized by the com express BIOS, it depends on the manufacter. [...] Then, I think that the hardware is working but I need some initialization in the southbridge or something else that the first BIOS is doing. Where can I looking for this info? Both com express modules has the intel ICH7-M southbridge.
I'd say the best way forward is to diagnose this with the help of superiotool. Make sure the w83627hf kernel module is not loaded automatically, then run superiotool -dV and compare the outputs. If superiotool finds your SuperIO only on one of the boards, you most likely have a southbridge resource configuration problem which needs to be addresses by the BIOS manufacturer (or a custom early kernel driver). If superiotool finds your SuperIO on both boards, compare the settings and work from there.
