Traildriver is absolutely correct. Even if you could (though not legally) the new machine, I'm guessing, is running a 64 bit version of Windows and probably has more than 4GB of RAM. The Windows XP version on the recovery disks is probably a 32 bit version which will not recognize (utilize) more than 4GB of RAM. If you decided to go with a 64 bit version of XP you would need the 64 bit drivers.
I think Traildriver's response is the best answer.
