Two drives on a PC

Dear Friends,

I have two hard drives - SATA (160GB) and IDE (old
40GB). I have installed my same copy of Windows XP sp2 on both drives, separately.

When I connected the drives to my PC, it
automatically booted via the SATA drive and showed the other as additional
disks E and F (or G and H - I don't clearly remember).


So, I could not run the
programs installed on the IDE drive though I could use its space for storage.

Please let me know how I can use both together on
the same PC, to avail of different programs/software on both, without going
into the bios every time I start my computer.

1. Is there a way to have an option provided automatically on start-up, so I can chose which Hard Drive to work
with?

2. Could I switch from one Hard Drive to the
other,without restarting my PC?

With thanks,
