Will you be installing Windows XP?
If so, start up and boot to the Windows CD. Right when it starts, it will say to hit F6 to load SCSI or Raid drivers - do so. The Mobo comes with a floppy drive that has the XP drivers(at least my NF7-S did) - you will have to direct the setup program to the floppy where the drivers are - it should then load the drivers and continue on as per usual.
