During a clean installation of Windows Millennium Edition (Windows Me), your computer may stop responding after you first restart it. Your computer may also stop responding after you restart it the second time while detecting hardware. The computer will start in Safe mode, however Normal mode is required to complete the installation.

There are no drivers for the Accelerated Graphics Port (AGP) functionality, which VIA Technologies uses with the MVP3 chip set. The driver Viagart.vxd is not included in Windows Me, and may be installed from the distribution media for the specific video display adapter or motherboard utility program for your computer.

VIA develops chip set solutions for many different motherboard manufacturers. Therefore, the chip set may vary from one computer to another, or from one version of the driver to another.

NOTE: Before attempting the resolutions described in this article, you must obtain the display drivers for AGP, and for the chip set used in your computer from the motherboard manufacturer.

VIA Technologies provides chip sets to many manufacturers. Each manufacturer may implement the VIA design differently. For information about how to contact the manufacturer of your motherboard, click the appropriate article number in the following list to view the article in the Microsoft Knowledge Base:
Use any of the following three methods to work around the problem:

Method 1

Install the utility driver for the AGP card in Safe mode, from the media on which the driver is provided.

Method 2

Obtain the AGP utility driver support from the manufacturer of the motherboard, from the AGP adapter manufacturer, or from VIA Technologies directly.

VIA has an AGP patch (Agp403.exe) available for download. This file is a self-extracting tool that expands the needed files to the location where you have Agp403.exe stored.

After the files are expanded, you can run the Setup.exe utility for the patch in Safe mode. After you install the adapter driver, restart your computer in Normal mode to continue Setup Windows Me.

Method 3

If you are unable to use Method 1, or Method 2, editing the registry may be the only solution for the problem.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

1.	In Safe mode, click Start, click Run, and then type regedit.
2.	Delete the following registry keys: HKEY_Local_Machine\System\CurrentControlSet\Services\VXD\ PCI\GARTMiniPorts\03911106 HKEY_Local_Machine\System\CurrentControlSet\Services\VXD\ PCI\GARTMiniPorts\05011106 HKEY_Local_Machine\System\CurrentControlSet\Services\VXD\ PCI\GARTMiniPorts\05971106 HKEY_Local_Machine\System\CurrentControlSet\Services\VXD\ PCI\GARTMiniPorts\05981106 HKEY_Local_Machine\System\CurrentControlSet\Services\VXD\ PCI\GARTMiniPorts\06011106 HKEY_Local_Machine\System\CurrentControlSet\Services\VXD\ PCI\GARTMiniPorts\06911106
3.	Quit the registry editor, and then restart your computer. Windows Me Setup should continue in Normal mode to completion.

This issue may occur on computers that use the VIA Technologies MVP3 chip set and certain AGP video cards.

This issue occurs with the following chip sets: EPOX EP-MVP3G and EP-MVP3G-5 (2-Meg Cache version), and the ATI Rage 128 AGP and ATI Rage 128 AIW AGP display adapters. This issue also occurs on the FIC VA-503+ motherboard with the ATI Rage 128 AGP card.

This issue is not limited to these specific hardware configurations. The problem may occur with AGP adapters of various brands, including the following AGP cards or chip sets:

•	ATI
•	3DLab
•	ATIRage128
•	TNT
•	S3 3D

With AGP functionality, the adapters receive code and data from separate IRQ structures provided by the specific chip sets. If the Viagart.vxd driver is not installed prior to running Setup for Windows Me, the interrupts may be misinterpreted by the video display adapter, and the wrong information will be received. This will cause the video subsystem to stop responding, at which time Windows Me Setup stops responding.
