You'd replace the crystal oscillator on the motherboard with a more stable reference. The TAPR Clock-Block (http://www.tapr.org/kits_clock-block.html) is a synthesizer designed for that purpose; it can take a 5 or 10 or whatever MHz input signal and convert it to the clock frequency needed by the motherboard. An example of doing this is at http://www.febo.com/pages/soekris where I convert a single board computer into a very precise timekeeper using a Clock-Block and some other hardware hacks.
