So I have a crappy old system I dredge out when I need to try a quick experiment. Pentium-D on an intel server MB with 8GB ram. I hauled it out last night to throw 6.0 on it to test something, and it PSOD'ed with a message about unsupported CPU type. Looking at the 6.0 release notes, all I saw was something about 3 amd opterons not being supported. Not that this is a big deal, just curious...
