XP Pro on Server SOLVED

I was given an older server with NT. with dual 500mhz processors on board and two HDs. 512 meg RAM.
In reformatting the larger drive C to take XPPro installation, I assumed that it would reformat the drive D HD as well or be offered the option.
Now all I see is drive C, and drives E,F,G with no values. Where did drive D go? Do I need to run the setup again for this drive D and reformat to allow XP to recognize drive D.
Do the two on board processors work in tandem and is there a way of maximizing their abilities? I am in unknown territories.
SOLVED:
I REINSTALLED AND REMOVED ALL PARTITIONS .
XPPRO ACTUALLY SET THE COMPUTER UP FOR MULTIPROCESSORS.

 

Go to computer managment from control panel.
Go to logical drives.
What do you see there?
