SYMPTOMS
After you upgrade to Windows 98, you may see two CD-ROM drives listed in My Computer even though you have only one physical CD-ROM drive in your computer. Also, you may notice that the second drive is reported to be using MS-DOS Compatibility Mode Paging if you view the Performance tab in the System tool in Control Panel.



CAUSE
This behavior can occur if you manually assign a drive letter to your CD-ROM drive on your Microsoft Windows 95-based computer, but you leave at least one unused drive letter. If you then upgrade to Windows 98, the unused drive letter and the original drive letter are mapped to the same CD-ROM drive.



RESOLUTION
To resolve this issue, use the following steps:


 * 1) Click Start, point to Settings, click Control Panel, and then double-click System.
 * 2) Click the Device Manager tab, and then double-click the CD-ROM branch to expand it.
 * 3) Click the second CD-ROM listed under the CD-ROM branch, click Properties, click the Settings tab, and then change the Start drive and End drive letters to be the same as the drive letter for the first CD-ROM drive.
 * 4) Click OK, click OK, and then restart your computer.
