I am building a new computer with an ASUS P5K Deluxe MB, a WD 500GB SATA HD, and one EIDE CD/DVD drive and one EIDE CD drive. When I first booted the computer, it saw the CD Drive, loaded windows XP with no problem. Now I want to load the ASUS drivers, which are on a DVD, so I can get on the internet, etc. I installed a liteon model SHW-160P6S CD/DVD drive. Windows will not detect either cd or cd/dvd drive. The BIOS does not show these drives either. Disk management does not show these drives. How do I get my system to recognize these drives?
