Two Hard Drives

[TheCommander]

So I plugged in my old hard drive and am going to use it for data storage. But I was wondering why Windows did not give me the option of which hard drive to boot from. I have Windows XP installed on both of them and Windows boots from my Raptor.

Is there anyway I can choose which drive to boot from?
The Raptor is connected to a SATA port and my old drive connected to an IDE slot.
