SYMPTOMS
========
If you use a Windows 3.0 video display driver (VDD) on a Packard Bell machine
and EMM386.EXE is installed, you receive one of the following error messages
when you run Windows in 386 enhanced mode:
The Winmemsize in SYSTEM.INI is too large
-or-
Kernel is corrupted
In addition, these same problems can occur when you use the Windows 3.1 Packard
Bell driver, HTVDD.386 VDD.
CAUSE
=====
Although HTVDD.386 is a Windows 3.1 VDD, it still uses the C600-C7FF range. This
situation is caused by a problem in the Packard Bell VDD, not Windows 3.1 or the
Windows 3.1 Device Developer Kit (DDK).
On some Packard Bell systems, the video BIOS is at E000 and C000-DFFF is free (by
default). EMM386.EXE uses this as range as upper memory blocks (UMBs). If you
are using a Windows 3.0 video display driver, Windows ignores anything loaded in
the C600-C7FF range. This can cause various problems in Windows, including
failure to run and failure of the Microsoft Backup for Windows compatibility
test.
WORKAROUND
==========
Windows 3.0
-----------
Add the X=C600-C7FF parameter to the EMM386.EXE command line in the CONFIG.SYS
file.
Windows 3.1
-----------
You can either use a Windows 3.1 video display driver (such as the standard VGA
driver), or add the X=C600-C7FF parameter to the EMM386.EXE command line in the
CONFIG.SYS file.
