VMB Limitations

VMB does not support:

  • VCPI and other non-DPMI DOS extenders
  • I/O to disk which bypasses the file system
  • Feature adapter sharing without a virtual device driver
  • Real-time or timing-critical DOS applications
  • Some copy-protection schemes.

    These limitations arise in the most part from the limitations of the MVDM environment, which are imposed in order to protect overall system integrity.
