Installation
~~~~~~~~~~~~
The Setup utility will query you about your preferred installation location
and the components you wish to install. You must restart your computer
before the changes take effect.
You can also use the standard Windows NT procedure to install the drivers
(without the MGA PowerDesk). The general procedure is the following:
- Right-click on the desktop, select 'Properties'. This will open
Display Properties.
- Select the 'Settings' tab.
- Press the 'Display Type...' button.
- In the Display Type dialog box, press the 'Change...' button.
- In the Change Display dialog box, press the 'Have Disk...' button.
- In the Install From Disk dialog box, type the location of the
G100 installation files (e.g. "A:\" or
"D:\WINNT").
- From the displayed list, select the model of your display adapter,
and press 'OK'.
- Answer 'Yes' to the Third-party Drivers dialog box.
- Press 'OK' in the Installing Driver message box.
- Press 'Close' in the Display Type dialog box.
- Press 'Close' in the Display Properties applet.
- In the System Settings Change dialog box, you should select 'Yes'
so that the new settings take effect.
Using MGA PowerDesk
~~~~~~~~~~~~~~~~~~~
Changing resolution, selecting a monitor, and using the MGA PowerDesk is
covered in the "online.doc" file. You can view this file with WordPad.
Registry settings (for advanced users only)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Information held in the Windows NT registry can have a direct effect on the
whole system. Introducing incorrect values can cause serious problems and
may make it necessary to reinstall Windows NT. If you accidentally modify
values that make your system unusable, please note that it is often
possible to undo the damage by using the 'Last Known Good Configuration'
option at boot time. It is also possible to save a copy of your registry
settings prior to any modification.
The configuration of the G100 Windows NT driver and of MGA PowerDesk is saved
in the registry. The most important parameters can be modified through the
MGA PowerDesk, but others can be accessed only through the Registry Editor.
Most users will find that the default values are best for their system.
However, specific problems will be solved through these switches. The
values are:
User.AlternateLines when set to 1, allows lines defined by integer coordinates
to be drawn using the faster AUTOLINE opcode of the
drawing engine. The convention used to determine which
pixels contribute to a given line is slightly different
in AUTOLINE and in Windows NT. Setting AlternateLines
to 1 trades off compliance with the Windows NT conventions
for performance. A value of 0 will enforce compliance.
Lines defined by non-integer endpoint coordinates are not
affected by this setting.
The default value of User.AlternateLines is 0.
User.CenterDialogs has no effect on Windows NT 4.0.
The default value of User.CenterDialogs is 0.
User.ComplexBlt when set to 1, allows the hardware to accelerate some
complex raster operations (ROPs) by executing a sequence
of simple ROPs (ORing, ANDing, etc...). A value of 0
will result in complex ROPs being performed in software.
The complex ROPs are performed directly on the display
through a succession of simple ROPs. Artifacts (flashing)
in the target display area may become visible when an
intermediate result in video RAM is displayed on a given
refresh cycle, to be replaced by the final image on the
next cycle.
The default value of User.ComplexBlt is 1.
User.DeviceBitmaps when set to 1, allows use of off-screen memory for
caching bitmaps. This will allow the hardware to
accelerate drawing to bitmaps. A value of 0 disables
bitmap caching, allowing the CPU to draw onto all
bitmaps. Bitmap caching is internally disabled when
a desktop requiring more than one card is in use,
regardless of the registry setting.
The default value of User.DeviceBitmaps is 1.
User.EnableUSWC when set to 1, allows direct frame buffer access to use
the Write Combining feature of the Pentium Pro processor.
Setting this value to 0 may result in slightly lower
performance.
The default value of User.EnableUSWC is 1.
User.MgaInfoFile when set to 1, allows use of the MGA PowerDesk to
control refresh rates. A value of 0 will allow all
available refresh rates to be listed.
The default value of User.MgaInfoFile is 1.
User.SynchronizeDac when set to 1, will require the driver to wait for a
vertical sync before programming the ramdac with a new
pointer shape or a new palette. If you notice stray
pixels flashing around the pointer, setting this flag
to 1 might fix the problem. Setting it to 0 will result
in slightly better performance.
The default value of User.SynchronizeDac is 0.
User.SynchronizeEngine when set to 1, will require the driver to wait for
the Millennium hardware to be ready to accept new data
before programming the next operation. Setting it to 0
will result in better performance.
On most x86-based systems, the PCI logic should ensure
that such a check is redundant. If you're experiencing
problems that might be related to timing (with
communication programs, for instance), setting this value
to 1 may be of help.
The default value of User.SynchronizeEngine is 0.
Modifying keys and values in the registry is done through the Registry
Editor. The Registry Editor can be invoked in the following way:
- Use Start/Run..., or open a Command Prompt window, and type
'regedt32'. Alternately, from the Windows NT Explorer, go to
SystemRoot\system32 and double-click on Regedt32. The Registry
Editor will come up.
To examine or to modify the values that govern the behavior of the G100 driver:
- Select the HKEY_LOCAL_MACHINE window.
- Travel down to the key named:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\mga64\Device0.
You will find the values in the right window pane. To modify any of
them:
- Double-click on the selected value.
- In the DWORD Editor, change the value to '0' or '1'. The new value
will take effect the next time you reboot.
PowerDesk settings are kept under the key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MGACtrl
and its subkeys.
Notes, Problems, and Limitations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Systems using more than one PCI bus
It is possible that a switch to a full-screen Command Prompt, or any
change of mode, will result in a blue-screen crash if a card is
installed on a PCI bus other than bus 0. The problem is under
investigation. Moving the card to a different PCI slot is a possible
workaround.
There are systems where Windows NT reports conflicts between adapters
installed beyond the PCI bridge. In this case, the G100 miniport
driver cannot access its own card. If your system appears unable to
find the card, try moving it to a different PCI slot.
The Service Pack 3 should address many of these problems.
DirectDraw on multiple cards
DirectDraw cannot currently handle direct access to a desktop spread
over multiple cards. Applications that require DirectDraw will not
run on such a desktop.
DirectDraw on virtual desktops
Some DirectDraw applications cannot currently handle virtual
desktops. It is recommanded that DirectDraw applications be
run from normal desktops.
ActiveMovie in full screen
Running clips in full screen at 256 colors with ActiveMovie may
result in a corrupted display while the clip is being played.
The problem appears to come from the application.
Corruption using the 3D-Maze screen saver
This problem appears only after installing the Service Pack 2 for
Windows NT 4.0. The problem is apparently fixed by the Service
Pack 3.
Zooming by 4 at 1152x864, 256 colors
A hardware limitation results in a vertical band of pixels being
displayed at the right edge of the screen, beyond the 1152 limit.
Running Winstone 97
The CenterPOPUP feature should be disabled (which is the default
setting) when running the Winstone 97 benchmark. Some tests may
time-out when CenterPOPUP is enabled.
