DESQVIEW AND AST SYSTEMS WITH BUILT-IN MOUSE PORT
|
||
|
|
|
||
|
|
|
||
|
|
PROBLEM: AST systems lock-up when using DESQview, with a mouse
|
||
|
|
connected to the mouse port.
|
||
|
|
|
||
|
|
AFFECTED
|
||
|
|
SYSTEM BOARD: All system boards with integrated mouse port and the following
|
||
|
|
part numbers:
|
||
|
|
|
||
|
|
202273-001, 202343-001, 202343-003, 202351-002 202352-001,
|
||
|
|
202360-001, 202373-001, 202377-001, 202385-001,
|
||
|
|
|
||
|
|
CAUSE: Incompatibility between DESQview release 2.31, and AST's
|
||
|
|
implementation of the mouse port.
|
||
|
|
|
||
|
|
SOLUTION: A permanent solution will be the next release of DESQview.
|
||
|
|
However, a temporary patch can be made by following the
|
||
|
|
directions below.
|
||
|
|
|
||
|
|
NOTE: All zeroes in the following text are underlined for
|
||
|
|
readers reference only.
|
||
|
|
|
||
|
|
Step 1: On the root directory of your Hard Drive create a file named
|
||
|
|
DVFIX.DBG using DOS's COPY CON command or any ASCII text
|
||
|
|
editor. The file should contain the following:
|
||
|
|
|
||
|
|
E 40:0F
|
||
|
|
F0
|
||
|
|
Q
|
||
|
|
|
||
|
|
Step 2: Add the following line to the AUTOEXEC.BAT:
|
||
|
|
|
||
|
|
DEBUG <DVFIX.DBG
|
||
|
|
|
||
|
|
The above instructions assume that the MS-DOS DEBUG.COM is accessible from
|
||
|
|
the root directory of your boot disk. If it is not, copy DEBUG.COM to the
|
||
|
|
root directory or make sure it is pointed to in your PATH statement.
