Bella, I've seen the Dr. Dos screen when my CD-Rom is set to boot first in my BIOS and my ASUS Motherboard CD is in my DVD burner. It sounds like you may have integrated more then just the RAID drivers from your CD, if that is the where you got your drivers from. I just started fooling around with nLite yesterday and successfully integrated the drivers by downloading the nForce4 drivers from the NVIDIA website as suggested on the nLite site. When I downloaded the drivers, I did see the option for Intel drivers (I'm an AMD person). I am assuming that you do have the NForce4 chipset. If so, here is the link to the drivers. http://www.nvidia.com/content/drivers/drivers.asp I hope this helps.
