  1. Have a win2k machine. When i go into MY Computer or Disk Management the cd burner (set to slave) and the cd rom (set to master) are not shown. if i go into device manager the drives are shown under DVD/CD Drives. they are shown in the bios and can boot off them. its just the OS does not see them. Also, i changed the transfer mode on the second ide channel in device manager, rebooted and same result. OS does not see them. I even changed the cd drives and same thing, os does not see it. need help with this one. thanks.
