I just bought ASUS Pundit-R barebone system. The motherboard is ASUS P4R8L. I installed Windows MCE 2005 on it and the other components are Intel P4 3.0E, 1GB memory (Rosewill PC-3200 512MB x 2), Western Digital 200GB SATA HD (WD2000JD), and Pioneer DVR-107D DVD/CD drive (I have not installed a TV tuner card yet). The installation of MCE 2005 itself went fine without any problems. Then, I wanted to install drivers for other Putdit-R built-in components such as vidio and network from the ASUS support CD. But, I noticed that the CD drive does not work. I mean it does not read CDs. It worked fine when I installed MCE 2005. But, it does not work after Windows is installed. The drive has been recognazed properly both from BIOS and OS. In the Device Manager, I see "Pioneer DVR-107D" under "DVD/CD-ROM drives" and its property page says "This device is working properly.". I uninstalled the device once and then it was automatically detected and the driver was reinstalled when I rebooted the PC. But, it does not read any CDs (I tried several CDs I have). I even reinstalled Windows MCE 2005, but the problem still persists. I looked at the system even log and I found out there are many cdrom errors there. It says: "The driver detected a controller error on \Device\CdRom0" What does it mean? I connected the Pioneer DVD/CD drive (which has been used in another PC without any problems) to the Primary IDE connector (black one, near the front of Pundit-R). The DVD/CD drive is the only one connected to the primary IDE connector as the hard drive has been connected to the Serial ATA connector and nothing has been connected to the secondary IDE connector (blue one, near to the power unit). I tried to connect the DVD/CD drive to the Secondary IDE connector instead of the Primary IDE connector, but the BIOS does not recognize the DVD/CD drive in such case. Please let me know what I should try at this time. Thank you very much!
