Hi, Peter.
Just make sure all the jumpers and cables are correct. Then plug it in,
boot into WinXP and use Disk Management to initialize it (if it doesn't
happen automatically), create partitions and logical drives, assign drive
letters and format them.
If you get lost, try the extensive Help file in Disk Management. Shortcut
to Disk Management: at the Run prompt, type: diskmgmt.msc
I'm assuming you are adding a new drive as secondary. If you are upgrading
to a new boot device, the steps are more complicated. Post back if you need
help with that.
