Hercules Graphite Display Driver Installation
How To Report A Bug To Hercules
IMPORTANT: Before You Begin
---------------------------
Display configurations for Windows NT are selected
from within Windows NT's graphical user interface (GUI).
IMPORTANT PRELIMINARY INFORMATION:
To avoid damage to your monitor and possible re-installation
of Windows NT, you must select only the Hercules Graphite
display configuration(s) that your monitor can support. The
documentation that accompanies your monitor will include
technical specifications listing the monitor's maximum
horizontal scan frequency (e.g. 31.5kHz, 35.5kHz...64kHz,
etc.). You should locate this information before making a
selection.
If you were to select a Graphite display configuration that
your monitor could not support (i.e. high resolution mode,
high screen refresh rate, etc.) the following scenarios could
occur:
1. You could run the risk of damaging the hardware
components in your monitor.
2. Because your monitor was not able to sync properly,
you might be unable to view Windows NT. In the worst
case, correcting this condition could require a re-
installation of Windows NT. However, if you have a DOS
partition (i.e. dual-boot setup), you could restore
Windows NT to a VGA display configuration. In order to be
able to restore Windows NT to a working configuration in
case of error: (a) make sure that Windows NT is currently
installed and operating with a VGA display driver, and
(b) copy the contents of Windows NT's
\WINNT\SYSTEM32\CONFIG subdirectory into a backup
directory in your DOS partition. If you were ever to
select a Hercules Graphite display configuration that your
monitor did not support, you could simply copy Windows NT's
configuration files from the backup directory contained
in the DOS partition back into Windows NT's
\WINNT\SYSTEM32\CONFIG subdirectory to restore Windows NT
to a VGA display configuration.
Step 5 contained in the next section titled "Hercules
Graphite Display Driver Installation" provides
information about the minimum horizontal scan rate
frequency required to operate each Hercules Graphite
display configuration. PLEASE READ CAREFULLY BEFORE
MAKING A SELECTION!
Hercules Graphite Display Driver Installation
---------------------------------------------
These instructions assume that Windows NT is currently
installed and operating with a VGA display driver. If this
is not the case, install Windows NT's VGA display driver
before proceeding with these instructions.
1. Launch Windows NT and locate the "Main" program group.
Double-click on the "Windows NT Setup" program item icon.
2. When the "Windows NT Setup" dialog box appears, choose
"Options" from the pulldown menu and select the "Change
System Settings" option.
3. Open the "Display" section and choose to scroll down and
click on the "Other (Requires a disk from a hardware
manufacturer)" entry. Click on "Close."
4. You will be prompted to insert the disk provided by the
hardware manufacturer. Place the Hercules Graphite
Windows NT Display Driver Diskette in a floppy drive
and specify that floppy drive for Setup. Click on "OK."
5. You will be presented with a list of Hercules Graphite
display configurations. Each display configuration
selection will list the graphics processor (AGX),
resolution, color pixel depth and screen refresh rate
(in Hz). To avoid damage to your monitor, select only
a display configuration (refresh rate) that your monitor
can support. The documentation that accompanies your
monitor will include technical specifications listing the
monitor's maximum horizontal scan frequency (e.g. 31.5kHz,
35.5kHz...64kHz, etc.). You should be certain of this
aspect of your monitor's operation before making a
selection.
Once you have determined your monitor's horizontal scan
frequency, consult the following table to select your
display configuration for your 1MB VRAM or 2MB VRAM
