did you run getpir? Run getpir under the normal bios and see if it matches 
what is in the bios you are building. I bet it doesn't. 

I think it might be a good idea to add the emcore to the tree, so if you 
can help me get this worked out we will add it.

Also folks I'm trying to get the STATUS pages up to date but our web site 
is in transition so give us a week or so.

Send me the dmesg output.

yes, I guess so. I would build a custom raminit.inc for this motherboard. 

Let's start by getting it into the tree, this will make your life a LOT 
easier.
