here's an update: first of all, the Asus call center is the most horrible call center on the face of the earth. everytime I call, I choose 1 for motherboards. then I get put on hold to wait for a tech. then I hear the ringing sound as if a tech is coming on the line. then I hear nothing for about 20 seconds and then i get disconnected. I had to do this over and over again untill I finally get through. this happened other days aswell. I chose this brand over ASRock for the support that I thought i'd get from them. so much for that. anyways, when I finally got through, the tech (who didn't seem to know what he was doing) suggested for me to try another HDD. so I plugged in my Seagate 160gb and low and behold, i was able to see the HDD in windows. during post when it shows the marvel controller, it does see the HDD. but for some reason, it doesn't see my WD raptor 74gb. but I still can't see these 2 controllers in the bios. the tech told me to take out the cmos batter and reset the bios by moving the jumper from pins 2-3. I wanted to do it this morning, but first I wanted to backup my current bios. I still have to do that. while playing around with my PC this morning, I unplugged the WD raptor, but broke the sata port on the HDD. so much for that HDD. questions: 1) should I reset the cmos and do you think it will have these marvel ports show up in the bios? 2) why would these ports see my seagate 160gb and not the WD raptor? I know the WD works.
