I just built a new system based on the Intel D955XBK Board with the 955 chipset. I am running Windows XP professional. I have 2 SATA Raid drives. My problem is that my CD-Rom drive, which is hooked up as IDE (updated firmware and using standard windows drivers), does not recognize any disk that is inserted into it after the system has started and will freeze if I try to use windows explorer to open the disk. The strange thing is that if a disk is in the drive during boot up, I can read and access the disk fine. Once I eject the disk however, the drive does not recognize either the same or another disk. I had a similar problem with a DVD drive that was also hooked up. Thinking that that drive was bad, I took it out and have ordered a replacement, but prior to sending it back I tested it in another computer and the drive worked fine. I have tried uninstalling the cd-rom drive and having it rediscovered upon reboot, but the problem remains. Any suggestions?
