Overview

The SciTech System Neutral Access Protocol (SNAP) Graphics for OS/2 IBM Special Edition (a.k.a. SNAP Graphics/se) is a set of graphic adapter device drivers (GRADD) supporting a variety of chip sets from the leading chip set manufacturers. SNAP Graphics/se is the new compatible replacement for previous versions of SciTech Display Doctor for OS/2 IBM Special Edition (SDD/se). SNAP Graphics/se supports many video features, including:

    * CRT Resolutions of 640x480, 800x600, 1024x768, 1280x1024, 1600x1200, 2048x1536, plus user-specified custom modes
    * All LCD (Flat Panel) Resolutions supported by the hardware
    * 16:9 HDTV-like Resolutions, including 848x480, 1072x600, 1280x720, 1360x768, 1600x900, 1800x1012, 1920x1080, 2048x1152
    * Support for all color depths
    * Unlimited Refresh Rates
    * DDC Plug and Play monitor detection
    * Full hardware 2D acceleration
    * Hardware cursor
    * Limited Feature support, including Zooming, TV Out, and Multi-Head (on selected graphic chip sets) 

Installing SNAP and switching from GenGradd/SDD to SNAP. Please print to have available during the installation process.

   1. Create a temporary directory in your system (don't use x:\snap - where x: is the boot drive)
   2. Hold down the Shift button and click on the link snapse214.exe.
      When prompted, save the file to the tempoarary location created in step 1, above.
   3. Open up a command window and attach to the temporary directory created above
   4. Invoke the file downloaded above with the -d -o options (very important)
   5. Attach to the system drive (very important)
   6. Issue the command: SETVGA (this will set your system video back to classic VGA)
   7. Reboot
   8. Attach to the temporary directory created above
   9. Issue the commands:

      set lang = EN_US
      setup SDD

      If you are not using the EN_US locale, issue the command SETUP (without parameters) to see the possible options.
  10. When prompted (regarding certain file to be over-written is newer), click OK.
  11. Reboot
  12. Remove the temporary directory created above
  13. Go to the "Screen" dialog box to select desired resolution and color depths.
  14. Go to page 2 of the screen dialog box and verify that your monitor is selected.
      If "Standard monitor types", or "Unknown monitor", or a wrong monitor is selected, select your monitor Manufacturer and Model from the list. 

When you have completed the installation, all the SNAP Graphics/se command line utilities will be located in the x:\snap directory, where x:\ is the drive where you have OS/2 located (i.e. your boot drive).

List of Supported Chips

This is a list of the graphics chipsets most recently supported by SNAP Graphics/se. For a complete list of all chip sets supported, refer to the readme.txt file in the package. 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 SNAP Graphics/se.

Recent additions include:

    * GM13:
      o ATI Mobility Radeon 9000 (M9)
    * GM12:
      o Service updates
    * GM11:
          o ATI Radeon 8500DV
          o Intel i845 Brookdale-G
          o NVIDIA GeForce2 Integrated GPU, GeForce2 Ti, GeForce2 MX 100/200
          o NVIDIA GeForce4 MX 420, GeForce4 MX 440/460, GeForce4 Ti
          o S3 ProSavage (VIA PM133), ProSavage (VIA KM133) 
    * GM10:
          o Matrox MGA-G550
          o NVIDIA GeForce3
          o Trident Blade 3D (VIA VT8601) 
    * GM9:
      o ATI Mobility Radeon (M6), Mobility Radeon 7500 (M7), Radeon, Radeon VE, Radeon 7500, Radeon 8500 

Supported Resolutions

Supported resolutions and color depths are adapter dependent and will vary depending on the amount of graphics memory, the chip set driver implementation, and the monitor selected/detected.
