- 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
- Hercules Graphite model:
