Troubleshooting DOSMAX

Microsoft Windows is a flexible environment.  It supports both DOS and
Windows applications.  Running DOS applications under Windows comes at
a cost, though.  Windows has its own overhead, and as a result less
DOS memory is available in a DOS window (a "DOS session") than if you
were running the DOS program from outside of Windows.  Using DOSMAX,
you can have up to 736 KB DOS memory, almost 100 KB more than with a
normal DOS window.	More memory means that most DOS applications run
faster and more reliably in a DOSMAX session than anywhere else.

The most important thing to remember is that you can only run text
mode applications under DOSMAX.  DOSMAX works in both Windows 3.1x and
in Windows 95.

Occasionally, you may find that DOSMAX for Windows does not work as
expected.  DOSMAX for Windows won't work under the following
circumstances.

* If there is software loaded at the top of conventional memory.  Most
resident programs load into the lowest address memory available.  If
the software loads into the top of low DOS memory, DOSMAX for Windows
won't work.  Though disk controller sofware is the most common
software that uses memory at the top of low DOS, CD ROM device drivers
sometimes configure a buffer in this area as well.	Certain viruses
have also been known to attach themselves to this area of memory.

* If your Qualitas MAX profile includes the option "NOXBIOS" (meaning
that Qualitas MAX is not relocating the extended BIOS into high DOS),
DOSMAX is disabled.  The extended BIOS normally resides at the top of
conventional memory.

* If you have a system with less than 640 KB base memory.  While
Qualitas MAX backfills this memory to 640 KB, these systems aren't
compatible with Windows.

If none of the above situations apply and you're still having problems
with DOSMAX for Windows, try the following steps.

* Exit Windows.  Add "DOSMAXMono=OFF" to the [Qualitas] section of
SYSTEM.INI.  Add the line [and the section if it doesn't exist].
Restart Windows and retry DOSMAX.

* Exit Windows.  Edit your 386MAX.PRO file and comment out (using a
semicolon) the "VGASWAP" and "USE=B000-B800" options.  Rerun Maximize
and see if DOSMAX works properly.

* If you're not using the standard VGA drivers that come with Windows,
check to see that you have the most current version of your video
drivers.  Also try the standard VGA drivers that come with Windows.
See your Windows documentation for more details.
