DEV.DOC - Documentation for DEV.EXE, DEV.ASM jgs 11/08/86

DEV is a utility to report device header information for all
installed device drivers, including the default drivers provided
with DOS as well as those installed at boot time by means of
"DEVICE=..." entries in the CONFIG.SYS file.

DEV requires PC-DOS or MS-DOS version 2.x or 3.x, and is invoked
by typing "DEV" at the system prompt. Typical results are as
follows:

............................................

History information:
--------------------

Version 1.0, dated December 12, 1984 and Copyright (c) 1984 by
Ray Duncan works for DOS versions 2.x and presumably 3.0, 3.1,
but NOT for 3.2. (See the comments in the .ASM file for further
explanation.)

Version 1.10 by jgs 11/08/86 (Jim Sack 72277,126) is a fix to
work with DOS 3.2. It will probably work with 3.0 and 3.1, but
has not been tested by the author of this revision. No change
has been made to operation under 2.x.

Anyone who verifies compatibility with 3.0 & 3.1 please update
the comments in the .ASM and this .DOC file and upload as version
1.11.
