I had a problem that was driving me nuts and I want to share the solution with all who may be experiencing the same.
I could not for the life of me get rid of the exclamation points on the IDE drivers in my system settings. This problem was also causing me not to be able to see any drives that were connected to the IDE ports on my computer.
but this is what fixed it for me and it was so simple it almost makes me cry....:

MS-DOS Compatibility Mode Problems with PCI IDE Controllers
--------------------------------------------------------------------------------
The information in this article applies to:
Microsoft Windows 95
Microsoft Windows 95 OEM Service Release, versions 2, 2.1
Microsoft Windows 98
Microsoft Windows 98 Second Edition
Microsoft Windows Millennium Edition
--------------------------------------------------------------------------------
If this article does not describe your hardware-related issue, please see the following Microsoft Web site to view more articles about hardware:
http://support.microsoft.com/support/windows/topics/hardware/hwddresctr.asp
IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.
SYMPTOMS
If your computer contains a Peripheral Component Interconnect (PCI) Integrated Drive Electronics (IDE) hard disk controller that employs serialization between the two IDE channels, you may experience the following behaviors:
32-bit file system access and 32-bit virtual memory are not available
-and-
Device Manager displays an exclamation point (!) in a yellow circle for the primary and secondary IDE channels
If you uninstall and then reinstall the hard disk controller, this behavior is not resolved.
CAUSE
This behavior can occur if the protected-mode driver for the hard disk controller is not properly initialized when you start Windows. When this occurs, a NOIDE value is placed in the registry which prevents Windows from making future attempts to initialize the protected-mode driver.
RESOLUTION
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT or Windows 2000, you should also update your Emergency Repair Disk (ERD).
NOTE: The purpose of the registry value that is mentioned in this section is to prevent damaged data. Before you modify this registry value, it is recommended that you perform the troubleshooting steps in the following Microsoft Knowledge Base article:
Q130179 Troubleshooting MS-DOS Compatibility Mode on Hard Disks
All Versions
To cause Windows to attempt to reinitialize the protected-mode IDE driver:
Click Start, click Run, type regedit in the Open box, and then press ENTER.
Locate and click the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\IOS
In the right pane, right-click the NOIDE value, and then click Delete.
Quit Registry Editor.
After you update the registry, restart Windows. Windows attempts to initialize the protected-mode driver for the controller. If Windows can initialize the protected-mode driver for the controller, the file system and virtual memory operate in 32-bit mode and Device Manager does not display an exclamation point in a yellow circle for the IDE channels.
If the protected-mode driver is not initialized properly, you receive an error message and the NOIDE value is re-created. Windows uses the MS-DOS Compatibility mode file system the next time that you start the computer.
Windows 98 Only
If you are running Windows 98 on your computer, locate the Tools\Mtsutil folder on the Windows 98 CD-ROM, right-click the Noide.inf file, and then click Install. When you do this, the NOIDE value is deleted if it exists. After you use this file, restart your computer.
MORE INFORMATION
This issue can occur if your computer has an IDE controller that requires serialization between the primary and secondary IDE channels. The protected-mode drivers for these IDE controllers may not be initialized if one of the following situations occurs:
If one IDE channel has a supported hard disk, and the second channel has a CD-ROM or another type of drive that requires Real-mode drivers. Because there must be serialization between the two IDE channels, Windows cannot access the hard disk in Protected mode and use the other device in Real mode. When this occurs, the Protected-mode driver is not initialized and the NOIDE switch is placed in the registry to prevent future errors. Both disk devices can then operate in Real mode.
-or-
If you manually remove the driver for the IDE controller from Device Manager and then reinstall it, or if you disable and then re-enable the protected-mode driver. Some PCI controller drivers are not designed for dynamic enabling and disabling, and can cause the Protected-mode driver to not initialize properly.
The Windows device drivers for the following controllers may cause this behavior:
CMD PCI-0640 PCI-IDE controller
Standard Dual PCI-IDE controller
Opti Dual PCI-IDE controller
Intel 82371 AB/EB Pci Bus Master IDE Controller
Ali M5229 PCI Busmaster IDE Controller
Other PCI IDE controllers that use serialization between the IDE channels may also cause this behavior.

I did the part using the Win98 cd rom and I am a happy camper!
Hope this helps!
