Authors/Port authors:

SciTech SNAP for OS/2 brings SciTech's proven universal device driver technologies to the OS/2 Operating System. Now with multihead and zoom features.

There will be no new versions of SNAP Graphics available from SciTech, but Arca Noae has licensed the source code:

This software is distributed as compressed package. You have to download and manually install it; if prerequisites are required, you will have to manually install them too.

Manual installation

Program is distributed as ZIP package: download to temporary directory and run the installer. See below for download link(s).

  • Free registration code for version 3.1.8 is available
  • IBM SDD/SE is the latest free version from IBM (2000)
  • Requirements: Warp 4, at least fixpak 5 or better; Warp 3, at least fixpak 35.

Please note:

  1. If your current display drivers came with an uninstall utility, please run it, as uninstalling them may solve some OS/2 and Win-OS/2 display problems. This step can be safely left out if you already have SNAP installed, in that case you can also skip step 2 below.
  2. Reset your system to VGA mode, before installing the SNAP drivers. Installing over the top of some display drivers does not always work properly.
  3. Once installed SNAP, the system should boot up in the 640x480x256 display mode. Once the system is up and running you can go to the 'Screen' page of the 'System' object to select all the available resolutions and color depths (you have to reboot for the changes to take effect). You can also go to the second page of the 'Screen' object.

Following ones are the download links for manual installation:

SciTech Display Doctor v. 7.0.4 (OS/2 IBM Special Edition, 12/12/2000) Readme/What's new
----------------------------------- SciTech Display Doctor 7.0 for OS/2 IBM Special Edition ----------------------------------- General Availability Release 1 ------------------------------ About SciTech Display Doctor for OS/2 ------------------------------------- SciTech Display Doctor for OS/2 brings SciTech's proven DOS and Windows device support technologies to the OS/2 Operating System. Although one of the core features of our DOS and Windows products is the support for the VESA VBE/Core standard, the OS/2 version has nothing at all to do with VESA services. Rather SciTech Display Doctor for OS/2 incorporates the new SciTech Nucleus, Graphics Architecture device driver technology to bring SciTech's device support to the OS/2 platform. SciTech Nucleus is a binary portable, OS neutral, device driver architecture. As binary portable drivers, SciTech can fully develop and test the core device drivers in the DOS and Windows environments, while being able to target any Intel x86 based OS as the runtime environment (such as OS/2). This essentially allows the OS/2 product to utilise the same SciTech binary device drivers as the DOS and Windows versions of the product, improving the quality and performance of the drivers for all supported operating systems. About the IBM Special Edition ----------------------------- The IBM Special Edition of SciTech Display Doctor is a version that IBM has licensed on behalf all OS/2 customers. The Special Edition contains a subset of the features in the full product, as outlined below: . Resolutions of 640x480, 800x600, 1024x768, 1280x1024, 1600x1200 . Support for all color depths . Refresh rates from 60Hz to 85Hz . DDC Plug and Play monitor detection . Full hardware 2D acceleration . Hardware cursor Runtime Requirements -------------------- SciTech Display Doctor for OS/2 requires a version of OS/2 Warp 3 or OS/2 Warp 4 in order to run. More imporantly, it requires at least Warp 3 with fixpack 35, or Warp 4 with fixpack 5 installed. If you have a version with earlier fixpacks installed, SciTech Display Doctor will refuse to install. Installation and setup ---------------------- To install SciTech Display Doctor, follow the directions below: 1. Unzip all the files into a temporary directory directory (something *other* than x:\sdd, where x:\ is your boot drive). 2. Run 'setup sdd' from the directory where you installed the files from above. 3. Reboot your system 4. The system should then boot up in the 640x480x256 display mode. 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. When you have completed the installation, all the SciTech Display Doctor command line utilities will be located in the x:\sdd directory, where x:\ is the drive where you have OS/2 located (ie: your boot drive). Important notes --------------- If you have the HPFS386 Local Security feature enabled, you must make sure that: . The x:\os2\drivers\nucleus directory is always readable . The x:\os2\drivers\nucleus\config subtree has read/write/create access for all users. Failure to do this will cause that your system won't boot unless the administrator is logged on. Restoring your system in case of failure: ----------------------------------------- If SciTech Display Doctor does not correctly boot on your system, you can easily switch back to the GENGRADD drivers to boot your system to a workable state again. To revert to GENGRADD, do the following: 1. Boot to an Alt-F1/F2 command prompt mode 2. Edit CONFIG.SYS file and change C1=SDDGRADD to C1=GENGRADD,SBFILTER 3. Delete the x:\os2\svgadata.pmi file 4. Reboot your system. If that fails you will need to revert to VGA mode and reinstall your prior display drivers. Removing SciTech Display Doctor: -------------------------------- We have now included an uninstall program you can use to completely remove SciTech Display Doctor and all it's components from your system. To remove SciTech Display Doctor, simply run the x:\sdd\uninstal.exe program (where x: is the drive where OS/2 is installed). It will remove all files, and revert your system to VGA mode. From there simply re-install your original display drivers. List of all supported chips: ---------------------------- This is a complete list of the various graphics cards that this version of SciTech Display Doctor supports. Please note that this list refers to the actual chips being used, not a board-level implementation. Thus you will not see any products from Hercules or STB on the list, but their products are supported because they use S3, Cirrus, Tseng, etc. chips. Also, any card with less than 512KB of memory cannot be supported by SciTech Display Doctor. . 3DLabs Permedia, Permedia 2, Permedia 2V . 3dfx Voodoo Banshee, Voodoo3 .

Tseng Labs ET6000, ET6100 . VESA VBE 1.2, VBE 2.0, VBE 3.0 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. GACtrl configuration 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. 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. GAOption options selection program ---------------------------------- This is a simaple command line program to allow you to override some of the useful options for the SciTech Nucleus drivers. To see the current list of options and settings, use the following command: gaoption show This will show all the options for the current device. Some of the more useful options are explained below: gaoption prefer32 [on/off] This option controls whether you would prefer 32-bit display modes over 24-bit display modes to show up in the list of available display modes for the SDDGRADD driver. The deault is to choose 32-bit modes in preference to 24-bit modes if the mode exists at both color depths, and both color depths are fully accelerated. Otherwise the highest performance mode is always chosen. gaoption noncert [on/off] This option controls whether the Nucleus drivers will allow non-certified device drivers to load on your system. By default all gold releases will only run on certified drivers, and will fall back on the VBE/Core drivers if the device support is considered experimental and not fully QA tested. However you can use this option to override this on your system, if you wish to play with the experimental drivers. gaoption nowcomb [on/off] This option controls whether the Nucleus drivers will attempt to enable write combining on your system for faster system memory to video memory transfers. By default write combining will always be used where possible, but if this is causing problems you may with to try using this option to disable write combining support. The most likely scenario would be for a new processor that has not yet been fully QA tested. NOTE: You will need to reboot before any of the options will take effect for the SDDGRADD display drivers. ---- END OF README.TXT ----
