ASUS P5K Deluxe will not recognize SATA RAID drive

I have just completed building a new computer with an ASUS P5K Deluxe WiFi board. I fired it up and no “beeps” to tell me if the video card, or keyboard, or memory, or any if there are any hardware conflicts. So far, so good. I get the initial screen to read the memory, the CPU, the mouse and the drives, but no hard drive. I have one EIDE CD Rom player installed, so I can install windows XP Pro and one SATA Western Digital WD5000YS RE2 RAID hard drive. When I go into BIOS it recognizes the CD ROM, but not the hard drive. The only reason why I am using this RAID drive is because I got such a good deal on it, but if it will not work on my system, I will get another drive. Is there something I am doing wrong, or should I get another hard drive? If I get another hard drive, should it be EIDE or SATA?
