Summary:
Protected-mode CodeView (CVP) versions 3.0, 3.1, 3.11, 3.12, and 3.5
and Programmer's WorkBench (PWB) versions 1.0 and 1.1 have problems
recognizing the built-in monitor of IBM P70 portables under OS/2.
Symptoms of this problem include the following error messages:
Product Error Message
------- -------------
CodeView Internal Debugger Error 0 at load time
PWB Inability to change from 43-line mode
Microsoft has confirmed this to be a problem in CodeView versions 3.0,
3.1, 3.11, 3.12, and 3.5 and PWB versions 1.0 and 1.1 (buglist1.00 and
buglist1.10). We are researching this problem and will post new
information here as it becomes available.
More Information:
This problem is directly related to the video configuration of the IBM
P70. In its documentation, IBM mentions briefly that it might be
necessary to type MODE CO80 to make some software recognize the
built-in plasma display. An added condition for PWB and CodeView is
the necessity of being in 43-line mode. PWB automatically places you
in 43-line mode no matter what your previous mode was, and thus gets
around this limitation. If you attempt to change the height switch
while editing, PWB doesn't complain but still stays in 43-line mode.
CodeView cannot make the mode change in the same way that PWB can. If
invoked without the above considerations, CodeView will crash with an
Internal Debugger Error 0. The following are several ways to work
around this problem if you want to use CodeView with this type of
configuration.
1. Type MODE CO80 or BW80 and invoke CodeView with the /43 switch.
2. Type MODE CO80,43 or BW80,43 before invoking CodeView.
3. Use an external monitor with the built-in VGA port.
4. Invoke CodeView from PWB, which makes the change automatically.
