If your computer contains a PCI-IDE hard disk controller that employs serialization between the two IDE channels, this tip may help you resolve a MS-DOS compatibility mode problem in Device Manager.
To cause Windows to attempt to reinitialize the protected-mode IDE driver, remove the 'NoIDE' entry from the registry key below.
After you update the registry, restart Windows. Windows will then attempt to initialize the protected-mode driver for the controller.
If no problems are encountered, the file system and virtual memory will operate in 32-bit mode, and Device Manager will not display an exclamation point in a yellow circle for the IDE channels.

Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\IOS]
Value Name: NoIDE
