Thank you for replying. Okay so I'll do the following:

-Install XP on the IDE Disk.
-Change SATA Disk to AHCI.
-Download drivers for XP to see the AHCI.
-Install Leopard on a partition of the SATA AHCI.

Sound good?

By the way, is it important how my Hard disks are plugged in when doing the things I said above. I think at the moment the SATA is master (or primary??) and the others slave..

Ty for your help.
