I had all the other drives disconnected. The DVD was not a sata.
I've manged to get it working. The sata drives on the Gigabyte site were wrong and I had to find the right ones.
So now I have re-installed XP and after a couple of updates I dl'd SP2.
Now my computer takes about 30 minutes to boot up!
I don't know if I need to re-install SP2 or if a further update will make it boot quicker.
I'm getting REALLY fed up with this *censored* thing.
