Problems with Hard Disk Controller After Upgrading to Windows 98

• Microsoft Windows 98

SYMPTOMS

After you upgrade to Windows 98, you may experience one or more of the following symptoms:

• Device Manager reports resource conflicts with your hard disk controller.



• Your computer runs very slowly.



• You cannot gain access to your CD-ROM drive in Windows 98 or in MS-DOS using real-mode drivers.
