Just connect both drives but make sure the new 120 is set to master and the old one to slave.
Set first boot device as CDrom in the bios
Start the PC with the XP disc in your CDrom drive, it will load all the necessary files.
It will show both drives, one already partitioned with your ME etc, the other (NEW) unpartitioned, so create partition on that drive, then NTFS format followed by the new XP setup.
Just make sure that you have the new drive highlighted when partitioning and formatting.
Set first boot device to IDE0 (When restarting)
Once into windows XP and the mainboard drivers have all been sucessfully installed, it should be a simple case of using windows explorer to copy over important data from the old drive to the new before formatting the old drive (in windows, just right click and format old drive to NTFS)
Then if you want, copy the same files back over onto the now virgin 40gig)
Note* you don't have to do the latter but it is nice to clean and tidy things in such a way, and start fresh.
