- Jovian SuperVIA video capture driver
- SVIA.EXE
- Oct 7, 1992
-
- The SVIA driver is a revision 6.1 scanner driver (see REV6.DOC for more
- information). Using an NTSC signal, this driver provides resolutions from
- 320x240 to 640x480. Using PAL signals, it provides resolutions from 320x290
- to 426x580. All resolutions are 16 bit color. The SVIA driver works with all
- current ZSoft products.
-
- You can run SVIA.EXE from your CONFIG.SYS, AUTOEXEC.BAT, other batch file, or
- the DOS command line. To manually add the device driver to your CONFIG.SYS,
- use a text editor to type the entry as it appears below.
-
- device=SVIA.EXE
-
- Be sure to include a path if the scanner driver is not in your root directory.
- Remember to include additional parameters when necessary.
-
- This driver supports the following features:
-
- SVIA
- ====
- Brightness Settings 1-255
- Hue Settings 1-255 (via Contrast control)
- Saturation Settings 1-255 (via command line "/2")
- Contrast Settings 0
- Automatic Brightness No
- Automatic Contrast No
- Resolutions (NTSC) 320x240,320x480,426x240,426x480,640x480 (NTSC)
- Resolutions (PAL) 320x290,320x580,426x290,426x580 (PAL)
- Scan Modes B&W, 8 bit gray scale, and 24 bit color
- Halftones none
- Enhancements none
- Maximum Scan Area full res for mode
-
- The SVIA scanner driver's optional command line parameters are listed below:
-
- /Ax = memory Address channel (0-7)
- /Cx = application Code (1-4)
- /H = display this Help text
- /? = display this help text
- /Mxxxx = Memory address (hex value)
- /U = Unload driver
- /V = Verbose messages and status displays
- /0 = Use PAL video mode
- /1 = Micro Channel board
- /2xxx = Saturation (0-255)
-
- See REV6.DOC for detailed information on the standard command line options.

- Manufacturer's Notes
- ====================
-
- Board addresses:
-
- /A0 = CC00H (default is for SVIA.EXE to search for the board)
- /A1 = D000H
- /A2 = D400H
- /A3 = D800H
- /A4 = DC00H
- /A5 = CE00H
- /A6 = D200H
- /A7 = C800H
-
-
- Currently, ZSoft applications have no provisions for directly controlling hue
- and saturation levels. The saturation level is set when the driver is loaded
- and the hue level is set using the contrast controls within the application.
-
-
- The Micro Channel version of the SuperVIA uses a slightly different method to
- communicate with the software driver. If you have a MicroChannel version, you
- must add the "/1" parameter in order for the driver to operate properly.
-
-
- Specify the address of the SuperVIA board as /A or /M to avoid any potential
- conflicts with other software and/or hardware in your system. If the /A or /M
- parameters are not supplied, SVIA.EXE will search memory for the SuperVIA
- board, possibly causing system conflicts.

-
- This message is displayed upon successful initialization of the SuperVIA
- hardward. The name and model of the board will be displayed.
-
-
- SVIA Error Messages
- ===================
-
- 'SuperVIA board not found'
-
- This message is displayed at initialization time if the scanner driver cannot
- successfully communicate with the SuperVIA hardware. If you get this error,
- check to make sure that the parameters specified with your device driver are
- correct. Also check to make sure that the SuperVIA hardware is properly
- installed in your computer.
