DESQVIEW COMPATIBILITY PROBLEM

DESQVIEW COMPATIBILITY PROBLEM
|
|||
|
|
|
|||
|
|
6 new models of the IBM PC-XT and 2 new models of the IBM PC-AT
|
|||
|
|
were announced by IBM on April 2, 1986:
|
|||
|
|
|
|||
|
|
o PC-XT: New Models # 267, 268, 277, 278, 088, 089
|
|||
|
|
|
|||
|
|
o PC-AT: New Models # 319, 339
|
|||
|
|
|
|||
|
|
These new models offer such enhancements as bigger hard disks,
|
|||
|
|
more system board memory, faster speed operation, and
|
|||
|
|
support for the enhanced personal computer keyboard (101 keys).
|
|||
|
|
|
|||
|
|
SUPPORT FOR THE NEW ENHANCED KEYBOARD BUILT INTO THE NEW ROM BIOS
|
|||
|
|
CHIPS INCLUDED IN ALL 8 OF THE ABOVE MACHINES MAKES IT IMPOSSIBLE
|
|||
|
|
TO BOOT DESQVIEW 1.02 AND DESQVIEW 1.10 ON THESE MACHINES WITHOUT
|
|||
|
|
MAKING A MODIFICATION TO THE DESQVIEW SOFTWARE. THIS IS
|
|||
|
|
INDEPENDENT OF WHETHER OR NOT THESE MACHINES ACTUALLY COME WITH
|
|||
|
|
THE ENHANCED KEYBOARD.
|
|||
|
|
|
|||
|
|
Specifically, the new XT and AT models do not recognize the "scan
|
|||
|
|
code" value generated by pressing the ALT key to bring up the
|
|||
|
|
main menu in DESQview 1.02 and 1.10. (The situation is the same
|
|||
|
|
in Quarterdeck's 1.0 and 1.20 versions). This BIOS change has
|
|||
|
|
also affected other PC software such as ProKey, Framework and
|
|||
|
|
SuperKey.
|
|||
|
|
|
|||
|
|
|
|||
|
|
THE SOLUTION: DESQVIEW 1.03 AND DESQVIEW 1.11
|
|||
|
|
|
|||
|
|
There are two new versions of DESQview:
|
|||
|
|
|
|||
|
|
o DESQview 1.03 SixPakPlus, Advantage!
|
|||
|
|
|
|||
|
|
o DESQview 1.11 SixPakPremium, RAMpage, RAMpage AT
|
|||
|
|
(requires
|
|||
|
|
AST EEMS product)
|
|||
|
|
|
|||
|
|
These new DESQview versions are identical to the previous
|
|||
|
|
versions (1.02 and 1.10 respectively) except for the following:
|
|||
|
|
|
|||
|
|
- They run correctly on BOTH old and new XTs and ATs
|
|||
|
|
|
|||
|
|
- They include a Self-Running Demo of DESQview on the
|
|||
|
|
disk. Simply type "DV" before DESQview is actually
|
|||
|
|
installed on the PC system. After installation, "DV"
|
|||
|
|
runs the program, not the demo.
|
|||
|
|
|
|||
|
|
- With AST EEMS cards, version 1.11 of DESQview provides
|
|||
|
|
faster, more reliable performance with FlashPak than
|
|||
|
|
is possible with DESQview 1.10. (FlashPak buyers who have
|
|||
|
|
RAMpage or RAMpage AT will get a coupon in their FlashPak
|
|||
|
|
manual for a free DESQview upgrade from Customer Service,
|
|||
|
|
as well as an upgrade for an updated version of AST's REMM
|
|||
|
|
software [also required] to be included on SuperPak 6.1 in
|
|||
|
|
June).
|
|||
|
|
|
|||
|
|
|
|||
|
|
UPGRADE PROCEDURE FOR BUYERS OF NEW XT'S AND AT'S
|
|||
|
|
|
|||
|
|
Anyone who purchases a new IBM PC-XT or PC-AT who has also
|
|||
|
|
purchased an AST product containing DESQview 1.02 or DESQview
|
|||
|
|
1.10, is entitled to receive a compatible version of DESQview,
|
|||
|
|
free of charge from AST. Here's the procedure:
|
|||
|
|
|
|||
|
|
|
|||
|
|
END USER UPGRADE
|
|||
|
|
|
|||
|

1. The end user must send in the following:
|
|||
|
|
|
|||
|
|
o Title Page to his DESQview manual.
|
|||
|

HOW TO MODIFY 1.02 AND 1.10 TO RUN ON NEW MACHINES
|
|||
|
|
|
|||
|
|
It is not difficult to modify DESQview 1.02 and 1.10 to run on
|
|||
|
|
the new XT and AT. The user simply needs to boot the DESQview
|
|||
|
|
program on an OLD PC or AT and create a "script" (macro) to
|
|||
|
|
reassign the ALT key to another keystroke, such as the grey "+"
|
|||
|
|
key. He should do this in a DOS window under DESQview, which he
|
|||
|
|
will save as the file "D1-SCRIPT.DVS". Then all he has to do is
|
|||
|
|
make copies of the file, one named DESQVIEW.DVS and another for
|
|||
|
|
each of the programs he'll be using under DESQview -
|
|||
|
|
"LT-SCRIPT.DVS" for Lotus, "D2-SCRIPT.DVS" for dBASEII, and so
|
|||
|
|
on. These should all be stored in the DESQview subdirectory
|
|||
|
|
(\DV) and he's ready to go.
