PRB: XMS Version Information in MS-DOS Window Incorrect

ID: Q83455

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK) 3.1

SYMPTOMS

In an MS-DOS window under Windows, the version number of the extended memory system (XMS) driver is not the installed XMS driver (started before Windows is started). It is a version of the XMS manager built into Windows. The same thing is true for the expanded memory system (EMS) driver, the DOS Protected Mode Interface (DPMI), and any other drivers that enhanced mode Windows virtualizes.

CAUSE

This is by design. When Windows starts, it takes over all the XMS memory from the original XMS, EMS, and DPMI drivers. When you open an MS-DOS box, Windows provides extended memory to the MS-DOS-based application. NOTE: The XMS manager is XMS 2.0 compliant.

RESOLUTION

It is not possible to retrieve the version number of the original provider.
