On the contrary, even server-class boxes powered by Xeon now come with P4s with HyperThreading, such that a real two-CPU box is seen by Linux as having four CPUs. I've deployed systems with one and two Intel Pentium 4 CPUs with HyperThreading enabled (such that the Linux kernel sees two and four CPUs, respectively). I use Debian Woody with a custom-built 2.4.27 kernel and have no problems at all. --> Jijo -- Federico Sevilla III : jijo.free.net.ph : When we speak of free software GNU/Linux Specialist : GnuPG 0x93B746BE : we refer to freedom, not price. -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
