Video Conflicts

Video conflicts are easily identifiable in many cases.	Common
symptoms include:

A blank screen on entering or exiting a program
Automatic rebooting
Strange graphics or characters on the screen

*  The system hangs after the Qualitas MAX initialization screen
*  The screen blanks when entering or exiting an application
*  Unusual graphics or characters on the screen.

Several regions in the high DOS area have predetermined uses.  The
first 128 KB (between addresses A000H and C000H) is for memory on
video boards.  Each kind of video display uses a different amount of
address space.	Just above the video RAM area is a 32 KB area
(C000H-C800H) for the ROM on many VGA video adapters. 386MAX
automatically identifies and does not map into the appropriate video
regions of most systems.  However, there are some circumstances under
which video cannot be accurately identified.

If you experience any of the symptoms listed above, Qualitas MAX may
have remapped high DOS memory into a region that the video adapter
needs or may also have unsuccessfully relocated the video ROMs via the
VGASWAP option.  To correct this conflict, disable VGASWAP and
USE=B000-B800 in the 386MAX.PRO file.  You may do this in Windows by
using the UMB/Adapters tab in QualitasToolbox to deactivate use of the
MDA (Monochrome Display Area) and VGASWAP.	When you make these
changes, Toolbox displays a message suggesting that you run Maximize.

You may more quickly test to verify that these changes resolve the
conflict by choosing exit, then exiting Windows, and rebooting the
system to activate the changes.  These changes result in a change to
the configuration of high DOS memory.  It is safe to ignore any
resulting error messages as resident programs load into low DOS
memory.  If the problem is resolved, it is important to rerun Maximize
at this time to reoptimize your memory configuration.

In a DOS environment, edit the 386MAX.PRO file to make the changes.
Use any text editor to look at the profile located in the Qualitas MAX
directory (QMAX is the default directory; yours may be 386MAX if you
upgraded from a previous version).	If there is a USE=B000-B800, or
any USE= in the B000 range, comment that argument out of the profile
by placing a semicolon (;) in front of the line.  Repeat the process
for the keyword VGASWAP.  Reboot the system to activate the changes.
