Introduction
The purpose of this document is to outline the steps necessary to run the Windows® 95 operating environment with Diamond’s graphic and video accelerators.  This document will answer commonly asked questions regarding Diamond products and the Windows 95 platform, as well as explaining how to get your Diamond product to operate under Windows 95. 
II.	General Questions
A.	What Diamond products are supported under the Windows 95 platform?
Almost all of our graphics and video accelerators are currently supported under the Windows 95 platform. Later in this document the exact installation steps will be described for all Diamond products.
B.	Under what version of Windows 95 was the testing done?
For the testing described in this document, the production  release version 950 was used.  This is the latest version of Windows 95.  If you are using an older version of the Beta Windows 95 software, some or all of the information may not apply.  We recommend that you try the steps described below for the Diamond product you own.
C.	How do I select a different refresh rate for my Diamond graphic accelerator?
This is a very common question to Windows 95 users.  At the present time, there is VxD support for most of the Diamond graphic accelerators currently shipping.  These drivers are located on the Windows 95 CD-ROM in the following directory:
		
X:\Drivers\Display\Diamond    
where X= the CD-ROM drive (usually D or E)

A more detailed explanation of the installation is listed in later sections.

The standard drivers which are installed within Windows 95 do not have support for the card VxD’s.  This means that when you install a Diamond graphic card and select a high resolution, the refresh rate is not automatically selected.  The result is that you may get an interlaced mode or a lower refresh rate at higher resolutions. 
D.	When is Diamond going to ship their own drivers?
Diamond is currently very busy at work developing our own drivers to work under the Windows 95 platform.  These enhanced drivers will provide you with additional performance and features you have come to expect with Diamond products.  This includes a revamped and improved version of the InControl Tools utility software for Windows 95.  Actual ship dates for these drivers have not yet been determined.  For more information,  please see the Compatibility listing document.
E.	How can I get new information regarding Diamond and the Windows 95 platform?
You can obtain the latest information regarding Diamond products and the Windows 95 operating environment from the following locations:
1.	See our Web Page (www.diamondmm.com)
2.	See our forums on American OnLine or Compuserve.
III.	Diamond Multimedia Accelerators supported under Windows 95
Following are the Diamond graphic accelerators that have been tested under Windows 95 build 950 .  All of the graphic accelerators noted below have been found to work unless otherwise noted.  If you do not find your graphic card listed, it may mean that Diamond has yet to test this graphic card with Windows 95.  This document will be updated periodically as more testing is completed.

These procedures assume that you already have the graphic accelerator installed in the system.

d)	Check your Viper VLB or Viper PCI manual for other troubleshooting ideas.
D.	Viper Pro Video / Viper SE

1.	Chipset Detection
Actual chipset of graphic accelerator:	Weitek P9100
2.	Overview

Our engineering staff is currently working on Windows 95 drivers for the Viper Pro Video and the Viper SE accelerator cards.  Drivers are expected shortly after the retail release of Windows 95.  As soon as these drivers are completed and tested, Diamond will make these drivers available through our usual channels.

IV.	Troubleshooting Windows 95 Issues
If you are having problems running Windows 95, consider the following troubleshooting ideas:
1.	When installing Diamond utilities for one of our graphic, sound, or audio/telephony products, install to a directory using the standard MS-DOS naming convention.  This means {Filename}.{Extension}, where Filename is 8 characters or less, and the extension is 3 characters or less.  
2.	Consult the back of your manual for your Diamond product for basic troubleshooting tips.  Most of these tips are still true.
3.	There has been some instances when vertical lines or other garbage appears on the monitor after running the GO’95 utility in the Autoexec.bat file.  If you experience this problem, you can press the <ESC> key once (or another key) to clear this garbage.  There is no ill-effects of this garbage.
4.	Some of our graphic accelerators do not properly work when the Custom option is selected within the xMODE or GO’95 utility.  If this is the case for the graphic accelerator you own, we recommend using one of the predefined monitors.
