Hi Gerhard:

I believe you can go to the AMD sight and get the ELAN reference diagrams. 
I designed a motherboard some time ago based on the ELAN SC400 (486 
processor, now obsolete).  The PCI card information is there.  I think I 
also have it. I may have purged it with some old stuff.  I will look today 
to see if I can locate it.  My scanner is down at the moment.  I will try to 
dig it out and get a new scanner.

Are you working on a test system?
Regards
Rich
