- SciTech Display Doctor for OS/2
- -------------------------------
-
- Installation and setup
- ----------------------
-
- Until we get a full installer program completed, installation and setup will
- be a bit of a pain and must be done with a bit of manual work. Follow the
- directions below to perform the installation:
-
- 1. Unzip all the files into the c:\sdd directory (make sure you use the
- -d option if you are using PKZIP!).
-
- 2. Install the SciTech Display Doctor OS/2 device divers. To do this,
- run the setup.cmd command file in the installation directory (should
- be in the same directory as this file).
-
- 3. Edit the C:\CONFIG.SYS file to make SDD the active display driver. The
- following lines need to be added:
-
- DEVICE=C:\OS2\SDDHELP.SYS
-
- 4. Reboot your system
-
- Once you get to this stage, you will have the SciTech Display Doctor
- device drivers installed on your system, and you can test them out with
- the GATest program to ensure that they are working correctly. GATest must
- be run as a fullscreen OS/2 program, and it requires the above SDDHELP.SYS
- helper device driver to be loaded.
-
- To run GATest, go into the c:\sdd directory and run the installed GATest
- program. This program should automatically detect your hardware and
- bring up a text menu allowing you to test your graphics adapter. Select
- the Interactive Test, select the color depth you will be running and
- select the resolution you will be running. If you see an image on the
- screen, there is a good chance this version of SDD for OS/2 will run on your
- hardware ;-).
-
- Once you have verified that SciTech Display Doctor supports your hardware,
- you can go ahead and install the SciTech Display Doctor GRADD drivers. To
- do this follow the directions below:
-
- 1. Restore the system to VGA mode operation if your are not running VGA
- (Alt-F1 when the OS/2 message appears in top left corner of screen, F3 to
- restore VGA under OS/2 Warp 4).
-
- 2. Install the SciTech Display Doctor GRADD device divers. To do this,
- run the sddgradd.cmd command file in the installation directory (should
- be in the same directory as this file). This will go through the
- process of installing the IBM GENGRADD driver, and then copy the necessary
- SciTech Display Doctor GRADD drivers over the top of the GENGRADD
- installation. When it is finished the SciTech Display Doctor system
- files will have been installed and GENGRADD will be the active display
- driver.
-
- 3. DO NOT REBOOT YET!!!
-
- 4. Edit the C:\CONFIG.SYS file to make SDD the active display driver.
- You should see the something similar to the following two lines in
- the file towards the end (added by the GENGRADD setup code above):
-
- SET GRADD_CHAINS=C1
- SET C1=GENGRADD,SBFILTER
-
- change these lines to read:
-
- SET GRADD_CHAINS=C1
- SET C1=SDDGRADD
-
- 5. Reboot the system and it should boot to 640x480x256 on the SciTech
- Display Doctor drivers.
-
- 6. Once the system is up and running if you go the 'System Properties'
- dialog box you should be able to select all the available resolutions
- and color depths (you have to shutdown for the changes to take effect).
- You should also be able to go to the second page of the 'Screen'
- properties tab and the listed monitor should be 'SciTech Display Doctor'
- which will allow you to use all the resolutions and color depths that
- our drivers support.
-
- NOTE: Due to inherent problems in the standard OS/2 'System Properties'
- display properties page, we can only allow resolutions up to
- 1600x1200 to be available. We are in the process of re-writing our own
- version of this properties page to eliminate this problem, which
- will allow for resolutions up to 2024x1536 as well as HDTV 16:9
- aspect ratio display modes.
-
- GAReport hardware report program
- --------------------------------
-
- This is a simple program which will load the SciTech Nucleus display driver
- for your hardware, and report the graphics hardware configuration.
-
- GATest compatibility test program
- ---------------------------------
-
- This program allows you to perform compatibility testing on the Nucleus
- device drivers, including testing the graphics modes, stereo modes (which
- won't work under OS/2 yet unless you have hardware stereo), DPMS Power
- Management and DDC communications.
-
- One of the other useful things that this program can do is allow you to
- adjust the centering and refresh rate control for all available display
- modes (including text modes for OS/2 command prompts!). Use the 'Centering
- and Refresh' menu item to change the refresh rate and centering values
- for individual display modes, or the 'Global Refresh Rate' menu item to set
- all display modes to a preferred refresh rate.
-
- Of course the centering and refresh control will eventually be controlled
- by our SciTech Display Doctor GUI control center, but that component is
- still under development and not ready for testing.
-
- NOTE: Changing the global refresh rate *also* changes the refresh rate
- for VGA text modes to your preferred value. You may want to reset
- the text modes back to 70Hz manually if the refresh rate controlled
- text modes cause problems.
-
- GAPerf performance profiler
- ---------------------------
-
- This program allows you to run some performance profiling on the Nucleus
- device drivers, which will allow you to see what sort of raw hardware
- performance your graphics card posseses. Try it out, you may find the
- results rather interesting...
-
- GAMon monitor selection program
- -------------------------------
-
- This is a simple program to allow you to select a monitor that is attached
- to your graphics card. Selecting a monitor will filter the available
- display modes and refresh rates depending on the capabilities of your
- attached monitor.
-
- To select a monitor you must know the manufacturer and model name for your
- monitor. To list all available manufacturers, use the following command:
-
- gamon mfr
-
- This will produce a rather long list, so you can narrow the list by entering
- the start of the manufacturer name like and list all monitors that
- manufacturer makes:
-
- gamon model nec
-
- which will list all 'NEC Technologies' monitors. Once you have found your
- monitor, you can select it by entering the partial manufacturer name and
- a partial model name like so:
-
- gamon select nec XP21
-
- which will select the 'NEC Technologies' 'NEC XP21' monitor.
-
- Of course this selection program is a bit archaic at the moment, and our
- SciTech Display Doctor GUI control center will allow you to select a
- monitor (and adjust the properties) much more conveniently in the final
- release.
-
- Registering the the product
- ---------------------------
-
- To register the software, run the included 'REGISTER.EXE' program from
- an OS/2 command prompt. When prompted, enter the exact user name EXACTLY
- AS SHOWN, INLCUDING CASE! Hit enter and enter the registration code,
- and the product should then be registered.
-
- Good Luck!
