AST Advantage! 6033s
(250-0403)            Groliers Video Issue             Faxback Doc. # 9738

The AST 6033SX system comes standard with MSVideo for Windows version 1.1.
In the CD-ROM upgrade kit available from Creative labs is the Groliers
MultiMedia Encyclopedia.  This uses the MSVideo for Windows version 1.0.
Video/animation clips from this CD do not run correctly on these AST
systems.  The video gives a blank square with proper sound, and "jittery"
animation.  

The way to correct this is to 'downgrade' the version of MSVideo used on
this computer system.  The following procedure should be followed:

1.  Install the Grolier's CD onto the system.  When prompted to install 1.0
    version of the MSVideo utility, click on OK to install.

2.  After completion of installation, click on the Grolier's icon to load.
    The black square with movement indicating animation appears, but with
    no animation.

3.  With the Grolier's CD still in the CD-ROM drive, expand these two files
    by typing the following:

    expand d:\0msvideo\mciavi.dr_ c:\windows\system\mciavi.drv
    expand d:\0msvideo\msvideo.dl_ c:\windows\system\msvideo.dll
    expand d:\0msvideo\msvidc.dr_ c:\windows\system\msvidc.drv
    expand d:\0msvideo\dispdib.dl_ c:\windows\system\dispdib.dll

4.  Check for proper operation by clicking on the Grolier's icon.  The
    square should come up, with video pictures showing the animation.

Note:  Some of the newer AST Advantage machines require a different
       directory entry for the expand commands.  If you receive an error
       message stating that the directory does not exist, use the following
       lines:

       expand d:\0msvideo\mciavi.dr_ c:\NGMECL\mciavi.drv
       expand d:\0msvideo\msvideo.dl_ c:\NGMECL\msvideo.dll
       expand d:\0msvideo\msvidc.dr_ c:\NGMECL\system\msvidc.drv
       expand d:\0msvideo\dispdib.dl_ c:\NGMECL\system\dispdib.dll

If you still experience problems with the videos, try the following steps:

Add the following line to the WIN.INI file, in the [DRAWDIB] section:

DVA=0

The "dva=0" entry turns off direct video access (DVA) and DCI,
components of Microsoft Video For Windows. DVA and DCI allow video
images to be sent directly to the screen. If an application detects
the display type incorrectly, problems can occur using DVA and DCI.
Some of these problems can be severe (such as general protection (GP)
faults in Gdi.exe). When you turn off DVA and DCI, video images must
be drawn through GDI. Although using GDI can be slower than direct
access, it is safer.

Change the video driver to the Generic SVGA video driver provided with
MicroSoft Windows 3.11

If you are in Windows exit to the DOS prompt.

1.  Type "C:" and press <enter>.

2.  Type "CD \WINDOWS" <enter>.

3.  Now type "SETUP" <enter>.

4.  On the Windows setup screen, cursor up and highlight the display line.
    The default driver is set to "CL-GD5426/28 v1.43 Windows drivers".
    Highlight it and press <enter>.

5.  Now move the cursor down to the Super VGA hires and select
    "Super VGA 640 x 480 256 Colors" by highlighting it and press <enter>.

6.  Press <enter> on "Accept the configuration shown above".

    Press <enter> on use current driver.

    If Windows setup asks for a path to the Windows 3.11 disk type "A:\"
    <enter>.

When you restart windows, your SVGA display driver will be running.
