Sorry, I just read every message David posted to amd64@ since January 2004 and I have only seen a reference that it has been explained too often :-) He also said that you only lose the space from 3.5-4 GB, not the full GB, and that the board can re-map that physical memory to > 4 GB. http://groups-beta.google.com/group/fa.freebsd.stable/browse_frm/thread/9dc99b2be7f23d4/2d6de607055b020d?lnk=st&q=freebsd-amd64+david+%224+gb%22&rnum=7&hl=en#2d6de607055b020d Any further hints what to look for?
