Thanks for the help - much appreciated.
By the way, the removable hard drive caddies (cost me about seven quid) plus a few old hard drives come in very useful. You can set up a separate o/s on each hard disk and merely swap them about. As they are all dedicated, there is no need to worry about partitioning and you can have a Windows free system. I've got three hard drives now, one with Windows, one with RH and one on which I'm about to load Mandrake. I just slip in whichever hard drive suits the mood!
