   Compaq Professional and Digital Personal Workstations.  It does not
   contain any Windows 95 or Windows 98 support.

The following functionality is supported:
- Full support for OpenGL (3D Graphics) acceleration
- Full support for GDI (2D Graphics).
- Hardware support for major DirectDraw functionality  (e.g. YUV
  colorspace conversion, ColorKey, Stretch Blt).
- Full support for 2D multihead (see section 6)

2. Files Included in the kit.

3. System Requirements

   Base Platform:       Compaq Professional Workstation XP1000;
                        Digital Personal Workstation 433a,
                        500a and 600a enhanced.
   OS Version:          Microsoft Windows NT V4.0 SP3


4. Installation

To install the driver, please perform the following steps:

- Log in as an administrator or as a user who has administrative
  privilege to change the display settings.
- Start the "Display" applet by right-clicking "Desktop" and selecting
  "Properties".  A window titled "Display Properties" will appear.
- Click the "Settings" tab.  This lists display configuration, like
  "Color Palette", "Font Size", and so on.
- Press the "Display Type" button.  A new window titled "Display Type"
  will appear.
- Press the "Change..." button in this window.  A new window titled
  "Change Display" will appear.
- Press the "Have Disk..." button in this window.  A window titled
  "Install from Disk" will appear.
- Specify the path(Net or floppy) where the unzipped files are and press
  "OK".  The "Change Display" window will appear with two sub-windows.
  Press "OK".
- Then follow the instructions and quit the control panel applet.  
- When asked if you want to restart the machine press "Yes"(or "No" to
  delay shutdown).  The new settings will take effect at next reboot.
- After reboot, you can select the right resolution suitable for your
  needs.


5. Display Properties panel

The Display properties panel ("ntpanel.dll") is provided to help you
tune your display driver.  However, we strongly recommend that you
choose the system defaults.  This applet is integrated into the Display
Properties in the Desktop.

- To start the optional tuning applet: Right-click on the "Desktop" and
  select Properties.  A window titled "Display Properties" will appear
  on the Desktop.  Click on the "4D10T" tab and customize the settings.

Once you have chosen the settings:

- Select the "OK" button to confirm your selection.  If you selected a
  boot option parameter, a new dialog box will ask if you would like
  to reboot.

- Select "Yes" to restart your machine.  The new setting will only take
  effect on the next reboot.
    

6. Multihead

Compaq's Driver for ELSA GLoria Synergy supports homogenous 2D multihead
on the Alpha platform.  You can have up to three ELSA GLoria Synergy
devices on a system.  There is no support for heterogeneous multihead
(i.e. mixing 8MB ELSA GLoria Synergy devices with 4MB or 8MB PowerStorm
4D10T devices on the same system even though it may seem to work).

To enable Multihead, perform the following steps:

- Plug in the ELSA GLoria Synergy boards into the respective PCI slots.
- Disable VGA on all but one of the ELSA GLoria Synergy's.  The card
  which has VGA enabled will be the NT console.  This is where the NT
  boot messages will be displayed.
- Once NT boots, it is likely that you will see Graphics on only one
  card.  It is also likely that the card that has VGA enabled is not
  the card that displays the Graphics.  This is because the card that
  is plugged into the highest numbered PCI slot gets the priority to
  display the Graphics.
- After logging in, go to Display Properties and adjust the resolution
  to enable Multihead. This is explained in more detail in the
  file Multihead-Readme.txt.

Supported Configurations:

- Compaq Professional Workstation XP1000 - Up to Three
  8MB ELSA GLoria Synergy's

- Digital Personal Workstation 433a, 500a and 600a enhanced -
  Up to Three 8MB ELSA GLoria Synergy's
