Whereas it was previously running linux, it is now running FreeBSD. Everything seems to be going great, except linux was able to make use of it's 6GB of memory, and FreeBSD can only see about 4GB of it. Can anyone help me figure out how to make use of the missing GB? I'm happy to copy and paste any information I can to see if anyone can help, but for starters, here's the head of dmesg: # dmesg | head -40 Copyright (c) 1992-2007 The FreeBSD Project.
