Hi, I just bought an HP two weeks ago and it came with xp pro. I installed vista and played with it for a while and decided to scap it and install win server 2003 as my OS. During installing, win server cannot find any harddrive in my machines. I have two Seagate SATA hd one of 160gb and the other of 780gb which i added on after i got the machine from HP. I got hold of HP support and they said that xw4400 workstation only support win xp pro and vista business and they couldnt help me if otherwise. How crappy is that. I bought a machine close to $3000 and im locked into using specific OS. The second time i spoke to HP support, the gentleman was nice enough to point me to download intel@matrix storage manager and copy the drivers to and disket and do an F6 install. So I did exactly what he told me and im able to see all the controllers but even after that, win server cannot find any harddisk in my computer. Can anyone tell me whats wrong. Please I need help. I have had this machine for almost 3 weeks now and havent been able to use it at all. Please!!!!!!!
