A 32-bit kernel cannot take advantage of the 8 additional registers on your x86_64 processor. IMHO, you are much, much better off with a 64-bit kernel. With a 64-bit kernel you can run both 32-bit and 64-bit applications. There are very few reasons that I can think of to use a 32-bit kernel (I'm biased since I have been 64-bit since the before Dec Alpha was released). Probably one disadvantage of running a 64-but system is that you need both 64-bit and 32-bit libraries. But, considering you are getting a quad core chip and 8MB RAM, it would be quite a waste. If you want a 32-bit Fedora, run it in a virtual machine. KVM and Virtual Box should run very nicely in your configuraiton. -- Jerry Feldman <gaf@xxxxxxx> Boston Linux and Unix PGP key id: 537C5846 PGP Key fingerprint: 3D1B 8377 A3C0 A5F2 ECBB CA3B 4607 4319 537C 5846
