If you have Windows 95, Windows 98, Windows Me, Windows NT, Windows 2000, or Windows XP installed on your machine, please download the full SciTech SNAP Graphics Package and install it from within Windows. Because this package is provided as a covenience to our users who do not have a version of Windows installed on their machines, we have not provided any documentation in this package. For full documentation on the product please refer to the full Windows based package. Please note that we no longer support the DOS UniVBE 16-bit TSR driver; instead we support the SciTech SNAP drivers for 32-bit DOS applications. About SciTech SNAP Graphics --------------------------- SciTech SNAP Graphics incorporates the SciTech SNAP Graphics Architecture, which is a cross platform device driver technology enabling the use of the same device drivers on all supported platforms and architectures. Sharing the drivers between platforms improves the quality and performance of device drivers for all supported operating systems. Benefits of SciTech SNAP Graphics --------------------------------- * Plug & Play. SciTech SNAP Graphics will automatically detect your graphics card and monitor. You don't have to try and figure out what kind of graphics chip you have and then try to track down your vendor for a possible software upgrade. If you ever change your graphics card, SciTech SNAP Graphics will automatically detect the change and reconfigure itself for your new hardware. * Protected Mode/Linear Buffer Support. You can use a 32-bit protected mode interface, giving you as much as 2-3 times the performance of the older VESA interface. * Display Centering. SciTech SNAP Graphics allows for centering and sizing the display image on your monitor, for all supported graphics modes. * Refresh Rate Control. You can control the refresh rate, so you can set your display for the highest possible flicker-free image in each mode. * VESA GTF Support. SciTech SNAP Graphics can use the VESA GTF (Generalized Timing Formula) standard to automatically calculate exact refresh rates and display sizing. This makes centering graphics modes much easier. * Performance Profiling. SciTech SNAP Graphics includes display profiling programs that allow you to test raw bandwidth of your graphics subsystem. The profiling programs are low-level hardware oriented tests that can tell you the baseline performance level of your card.

GAMon monitor selection program ------------------------------- If you have a plug and play (DDC) monitor, SciTech SNAP Graphics will automatically detect its capabilities. If your monitor is not detected, you can configure it using the command-line GAMON utility. GAMon 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 display the current monitor configuration, use the following command: gamon show 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 as below, 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. If you need to make a selection with spaces in the name, use the quoting characters: gamon select "NEC Technologies" "NEC XP21" If your monitor is not listed, you can add it to the database. The majority of monitor manufacturers include INF files for Windows 9x with their monitors, and/or provide them on their web sites. You can import these files using: gamon import <filename.inf> where <filename.inf> is the name of the INF file. GAReport Hardware Report Program -------------------------------- This is a simple program which will load the SciTech SNAP display driver for your hardware, and report the graphics hardware configuration. GACtrl configuration program ---------------------------- This program allows you to perform compatibility testing on the SNAP device drivers, including testing the graphics modes, stereo modes, 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. 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. GAOption options selection program ---------------------------------- This is a simple command line program to allow you to override some of the useful options for the SciTech SNAP 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 accel [none | basic | most | full] This option controls what hardware acceleration features are used by the drivers. By default full hardware accleration is enabled. If you have problems with the mouse cursor, try 'most', which will disable hardware acceleration of the mouse cursor. The 'basic' setting will allow for basic acceleration features and is useful if you have problems with line drawing or text. The 'none' option turns off all hardware acceleration in the driver. gaoption vbe [on | off] gaoption vga [on | off] These options control whether the VBE/Core or VGA fallback drivers are used by default, or whether the native hardware accelerated drivers are used. By default these options are off, but you may want to enable one of them if the native driver has problems on your system. gaoption prefer32 [on | off] gaoption prefer16 [on | off] The prefer32 option controls whether you would prefer 32-bit display modes over 24-bit display modes. The default 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. Similarly, the prefer16 option controls whether you would prefer 16-bit display modes over 15-bit display modes. gaoption noncert [on | off] This option controls whether non-certified SNAP drivers will be used. If this is turned off when there is no certified driver for your card, the VBE fallback driver will automatically be used. gaoption nowcomb [on | off] This option controls whether the SNAP 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 wish 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. gaoption noddc [on | off] This option controls whether SNAP will attempt to read DDC information from your monitor. By default, this option is off (DDC detection is used), but if you think this is causing problems you may wish to try turning this on. gaoption agpfwrite [on | off] This option controls whether the SNAP drivers will attempt to enable AGP FastWrite for your video card. This feature is not available on all motherboards and video chipsets, but can significantly improve performance when enabled. By default, this option is on, but if you think this is causing problems you may wish to try turning this off. gaoption lcdusebios [auto | on | off] This option controls whether the LCD BIOS is used on laptops. This option defaults to auto, which means that the BIOS will be used when the laptop is booted on the LCD panel, and will not be used when it is booted on an external CRT monitor. If you frequently switch between LCD and CRT screens, you may wish to set this option to on, so that the graphics modes will be limited to those that can be properly displayed on the LCD panel. gaoption agpmem [memsize] This option controls how much system memory to allocate to video. It only has an effect on video chipsets that use AGP memory; currently the Intel i810 and i815 chipsets are the only ones that do so. The memory size defaults to 4096 Kb, but can be changed as desired. gaoption usesysmem [memsize | off] This option controls whether the system memory driver is used. It is only useful if you have no video card, as there will be no graphics displayed on any attached video cards; remote control software must be used. This option defaults to off, to enable it you must use a minimum of 512 Kb. GAPerf Performance Profiler --------------------------- This program allows you to run some performance profiling on the SNAP 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... GAMode Dial-A-Mode Utility -------------------------- When SciTech SNAP Graphics is installed, it comes pre-configured with a set of useful display modes that most users will find useful. The GAMode program allows the user to tailor the list of display modes to suit their tastes, allowing modes to be removed from the list, custom modes to be added, and custom refresh rates to be added for a particular mode. To show the list of currently configured modes and refresh rates, use: gamode show To add a new custom resolution to the list of modes, use: gamode add <xres> <yres> <bits> where <xres> is the desired X resolution, <yres> is the desired Y resolution and <bits> is the desired color depth (0,4,8,15,16,24 or 32, where 0 is for text modes). When a new mode is added, all refresh rates from 60 Hz to 100Hz will be added in 5 Hz increments. To add a new custom refresh rate for a particular resolution, use: gamode addref <xres> <yres> <refresh> where <xres> is the desired X resolution, <yres> is the desired Y resolution and <refresh> is the desired refresh rate in Hz. To specify an interlaced refresh rate, use a negative value (ie: -87 for 87 Hz interlaced). To remove a mode from the list of supported modes, use: gamode del <xres> <yres> <bits> where <xres> is the desired X resolution, <yres> is the desired Y resolution and <bits> is the desired color depth (0,4,8,15,16,24 or 32, where 0 is for text modes). To set the default refresh rate for a specific resolution, use: gamode set <xres> <yres> <bits> <refresh> where <xres> is the desired X resolution, <yres> is the desired Y resolution, <bits> is the desired color depth (0,4,8,15,16,24 or 32, where 0 is for text modes), and <refresh> is the desired refresh rate in Hz.
