Contents of the README file

Copy the directory \instance\exe to your harddisk.

To use the VxD's, simply start vxdload.exe. The TSR directs Windows to load
all three VxD's:
- vxdquery.386
- listinst.386
- listdvcb.386 (only under Chicago)

Important: You must start vxdload from the directory which contains the VxD's.

Use instwalk.exe to dump the data structures of the instance data manager.
Use vmcbspy.exe to dump a list of the privat VxD data in the Virtual Machine
Control Block.

Note: vxdquery is provided as a special version for the instance data manager
article in Dr. Dobbs Journal.

The professional version of vxdquery knows all published VxD services by name,
provides a complete map of all VxD objects and knows all control procedures
(Sys_Critical_Init etc) by name. Vxdquery works with all versions of MS-DOS
based Windows greater version 3.1.
Under development is a service of vxdquery that allows the user to type in so
called "dot-commands" in a DOS-Box. These commands are normally typed at a
kerneldebugger prompt.The dot-commands are part of the debugging version
of win386 (dos386) .EXE file. With dot-commands a developer can call any
available VxD (VMM) debugging services from a DOS-BOX, but without the need
to start a kerneldebugger.

To order the professional version of vxdquery, email to

CIS 100117,2526 (Klaus Mueller)

Have a happy rainy day with the VxD's!
