I just have to say, after hours of reading datasheets and examining  
code that who ever wrote the code for the e7520 and e7525 nothbridges  
is brilliant!! The way the code is setup is going to work perfect for  
me and maybe other people looking for Intel northbridge code starting  
points. I think if any of you working on the 440bx should just scrap  
the existing and start over with e7520 and e7525 as a template, maybe  
not, but you might be able to get it working this way. Anyways, I just  
wanted to Acknowledge some great code writing.

Thanks  - Joe
