SMBus Programming

SMBus Programming

I am working on a project with a WinBond interface chip on an
Intel ICH4-M equipped motherboard where I need to both read to and write from a device on the SMBus. I used a product called HWDirect from EProtek that has helped me do all of my troubleshooting and basic research and development, but now I need to actually put code in place to do this SMBus access.

EProtek told me there is an Intel document that would help with this sort of work; could someone please point me in the right direction for this documentation and, hopefully, give me any relevant information regarding this sort of work accessing a device on the SMBus?

Thank you in advance!
