Check your BIOS and see if there is a setting for the SATA controller in there. Your system might be a BIOS controlled harddrive controller where the setting is changed in the BIOS and it will auto boot to the right controller 
 
RAID set ups must use at least 2 seperate harddrives....stay away for this configuration. 
This is what I found for the model you gave and for using windows XP  
Drivers & Downloads 
There is a SATA driver and it has specific installation proceedures but only after it has been installed from what I read....Dell might be using a generic download/install note for covering all driver downloads....you might try it and  do the set up and see if this is what you are needing. 
Ususally a program called "Make Disc" is used to set up the correct media(floppy disc or cd) for installing SATA and/or RAID controllers during the F6 installation method.  
I think that you are going to have to take a look at the BIOS and make a determination!
