Q61557: P70 Display Creates Problems Under CodeView and PWB
Article: Q61557 Product(s): See article Version(s): 3.00 Operating System(s): OS/2 Keyword(s): ENDUSER | buglist3.00 S_PWB S_Editor | mspl13_basic Last Modified: 15-AUG-1990 CodeView version 3.00 and Programmer's WorkBench (PWB) version 1.00 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 with CodeView version 3.00. We are researching this problem and will post new information here as it becomes available. 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 you previous mode was and thus gets around this limitation. If you attempts 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 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.
