Well, I got it sorted. Cheers for all the advice, though. 

 I installed Win98, then put XP straight over the top of it without defining new partitions. So this leads me to another question - how do I change the existing partition (drive C:, FAT32, whole disk), to a primary partition and a few logical drives (C: 10GB, D: 50GB, E:100GB) without wiping the whole thing and starting again? If there's a way to do this, It'd be great, as I rushed through the install to get it up and running ASAP, but forgot about partitioning....

Man, that's wierd. I remember having similar problems a few years back, but then I was installing Win2k onto a SCSI setup (SCSI... man... haven't heard that for a while). So what happens if you skip the SATA driver setup and try to pass it off as a normal ATA drive? 
Doesn't work. It says "no drives detected, setup cannot continue" , and won't let me do anything....

That is so lame!!!
I can understanding it needing drivers to access the extra features SATA has over regulat ATA, but not for just formatting and copying files to it!!!

Cyker: Yeah it is a bit dumb so is the fact that you still need a floppy disk drive on a modern day PC of any sort.

What's even more retarded is the fact that Windows 98 had no problems at all, even though it came out 7 years before SATA! 
 
 Cheers - it is rather fast. Can't wait to try Far Cry on it (and Doom3 when it arrives) 

. It's cleaned me out, though, so no more toys for me for a while....
