Want to add scsi to XPS Dimension 400/9150

I have a Maxtor ATLAS 320 15K RPM HDD that I want to add to my XPS 400 and I have an scsi card that I traded from another Dell user, which is an ULTRA2-LVD/SE PCI.  The card is Dell also, made by Adaptec, but I cant find it listed, so it must be older.  I need to find the drivers so I can install and re-format the HDD.  I am still using XP and I doubt the drivers would be on the MS disk.  Thanks for any help.
