I thought it was when I ordered, and I just got it working as FWH, but I'm not having much luck using it with LPC (ie CK804). It looks like IDSEL needs to be inverted among other things.
I think the CK804 had 4MB rom decoded, if the code in LinuxBIOSv2 does what it says, so I don't think that's a problem any more.
Suggestions? Buy LPC for LPC boards and FWH for FWH boards?
Cheers,
Jeremy
