GLINT-Based Display Adapters Disabled in Windows 2000 on Upgrade. (256169)

SYMPTOMS

When you upgrade from Microsoft Windows NT 4.0 to Windows 2000 on a computer that contains a display adapter based on the GLINT accelerator chipset, the Setup program may display the following error message and disable the display driver:

The currently installed driver for the Glint based display adapter is not compatible with Microsoft Windows 2000 and will be disabled during the upgrade.

CAUSE

This problem is due to incompatibilities that exist between early versions of the driver and Windows 2000. Current drivers are compatible with Windows 2000, but are incorrectly disabled as well.

RESOLUTION

Download and install the latest drivers for the display adapter after upgrading to Windows 2000.

The latest drivers for the Oxygen VX1 can be found at the following Web site:

STATUS

MORE INFORMATION

The GLINT accelerator chipset is produced by 3Dlabs, and is available on display adapters from several manufacturers.

On upgrade, the Windows 2000 Setup program disables the driver for all display adapters that use a service key of "glint" in the Windows 2000/Windows NT 4.0 registry.

Additional adapters that are affected include the 3Dlabs Oxygen VX1 adapter, which is also Windows 2000-compatible. More information is available on the Oxygen VX1 adapter at the following Web site:
