I've been running FreeBSD 6.0 stable on an A8N-SLI Premium amd64 box with 2gb of ram for a few weeks now and it has been running well, but some of the analysis I run needs more ram, so I dropped in another 2 gb and started having all sorts of weird problems, such as DHCP failure and running very slowly. I tracked it down to 2 bios settings, both related to PAE (one turning on s/w PAE, the other h/w) - if i turn both of those off, then everything works, but FreeBSD can only see 3gb of ram. Some documentation suggested a custom kernel with 'options PAE' enabled would be required, but adding that generates an 'invalid option PEA' error when running make. Is it possible for FreeBSD to access the full 4gb on this m/b? Robert
