Dimension 8400 XP Install.

Hi!

I was recently given a Dell Dimension 8400 with a 3.0ghz Pentium 4 ht, 2 DVD Drives, 80gb hd, 1gb ram but no floppy drive.

I need to reinstall Xp, because it is running really slowly.

I have a Dell disc to reinstall XP Home Edition, but it says no hard drive when I try to install, because or Xp's lack of SATA drivers.

Is there like a setting in the bios I can change to fix this?

Thanks!
