Well, I don't think so. There is no such thing as KCS over I2C. There is something called the SMB interface, which is part of the newer IPMI driver version from openipmi.sf.net. I really don't know that much about it, someone else did that work and I don't have any hardware that supports it. But if you are running IPMI over I2C, that's probably what it is. Oh wait, the line: The Host interface of PC87431 is IPMI 1.5/2.0 SSIF (SMBus) means that it should support the standard interface that the IPMI SMB driver uses. IIRC, configuring it is kind of a pain, but it is supposed to work. -Corey > > mds > > > > > Ilia Stolov wrote: > >> Mark Studebaker <mds4 <at> verizon.net> writes: >> >> >>> ask National Semiconductor. >>> >>> Chan Min Wai (System Administrator) wrote: >>> >>>> Hello all, >>>> >>>> I'm on Ticket #1853 >>>> >>>> Is there anyway I can help to obtain a full data sheet? >>>> What kind of full data sheet do you need? >>>> >>>> What should be included? >>>> >>>> I would like to help in this, I've contact Intel Support and I think >>>> they will help in somewhere.
