So I recently inherited a dinosaur Dell Dimension 4600 from my dad (infamously on the list of the worst PCs by PCWorld, but my 4600 does not have the power supply issues). The computer is about 1/10 the speed of a snail, so I am reformatting and installing XP again. The PC has half-decent specs, besides a 40GB hard disk (I am almost positive it is IDE). So my questions are the following - How do I upgrade an IDE disk on the Dimension 4600? How big of a disk can I get, and what about jumpers - I've heard of them, but I have not used them before. My main concern is drivers. The XP disc that came with it is SP1. So will XP SP1 support a normal IDE drive, or will you need drivers for certain drives?
