BUG: Memory Use Greater With DPMI Memory Than VCPI or XMS (93093)
The information in this article applies to:
- Microsoft CodeView for MS-DOS 4.0
- Microsoft CodeView for MS-DOS 4.01
- Microsoft CodeView for MS-DOS 4.05
- Microsoft CodeView for MS-DOS 4.1
This article was previously published under Q93093 SYMPTOMS
When the memory manager provides DPMI memory, the CodeView debugger is
unable to load a very large MS-DOS application. However, CodeView can load
the application when the memory manager provides VCPI or XMS memory to
CodeView.
CAUSE
CodeView requires more than 64K conventional MS-DOS memory (addressed below
640K) when it runs with a DPMI memory manager and only 17K when it runs
with a VCPI or XMS memory manager.
RESOLUTION
If insufficient conventional memory is available when the system is
configured for DPMI memory, change the system configuration to provide VCPI
or XMS memory.
STATUS
Microsoft has confirmed this to be a problem in Microsoft CodeView versions
4.0, 4.01, 4.05, and 4.1. We are researching this problem and will post new
information here as it becomes available.
