One more note, which explains why I posted on the CentOS list: I have no problems installing Fedora 8, or Ubuntu Gutsy 7.10 on these boxes. I haven't tried CentOS4.6, but that's not an option. I need CentOS 5.X. I've been using CentOS from the beginning of the project. I won't consider another distro in production systems. -Ken ----- Message from kprice at nowyouknow.net --------- Date: Fri, 08 Feb 2008 18:56:58 -0500 From: Ken Price <kprice at nowyouknow.net> Reply-To: CentOS mailing list <centos at centos.org> Subject: [CentOS] CentOS 5.1 Core 2 Duo Install freezes To: CentOS mailing list <centos at centos.org> > Alrighty.
