The information in this article applies to:

Microsoft Windows NT Server version 4.0
Microsoft Windows NT Workstation version 4.0

SUMMARY

When you attempt to load a VESA video driver in a Virtual DOS Machine (VDM), the driver either fails to load or does not work properly.

MORE INFORMATION

Windows NT does not support loading VESA video drivers in a VDM. Even though some VESA video drivers may load properly and seem to function correctly in a VDM, this is not recommended.

Windows NT by design denies direct access to the hardware to all programs. Any program that tries to use direct hardware calls will fail in Windows NT.
