Making Hard Copy of the Document
================================

In order to print the documentation, you can type the following on the
command line:

copy dxp.doc prn

OR

type dxp.doc > prn


Installation Recommendation
===========================

It is recommended you use either the 32-bit or the 16-bit version of
Disk eXPress.  If you maintain both versions on your hard drive under
OS/2, the recommended setup for your LIBPATH and PATH may look like
this:

LIBPATH=.;C:\DLL32;C:\DLL16; ... C:\OS2\DLL;C:\OS2\APPS\DLL; ... ;
SET PATH=C:\OS;C:\OS2\SYSTEM; ... C:\BIN32;C:\BIN16; ... C:\FAMBIN; ... ;


C:\DLL32  -- for holding 32-bit OS/2 DLLs
C:\DLL16  -- for holding 16-bit OS/2 DLLS
C:\BIN32  -- for holding 32-bit OS/2 executables
C:\BIN16  -- for holding 16-bit OS/2 executables
C:\FAMBIN -- for holding OS/2 family and dual mode executables

Copy DXP.EXE to C:\FAMBIN.  Rename DXP32.EXE to DXP.EXE and copy it under
C:\BIN32.


Disk eXPress 32-bit and Extremely Fast Systems
==============================================

On the average systems, the 32-bit OS/2 version of Disk eXPress will run
faster than the 16-bit version by about 30%.  However, on extremely fast
systems (486DX-50, 486DX2-66, and Pentium), you may notice it running
slower than the 16-bit version.  This is due to the fact that the
compression thread is running just as fast as the diskette read thread,
and the 32-bit Device IO Control calls are somewhat slower than the 16-bit
counterpart.


Self-extract Executable and non-DOS diskette
============================================

Starting with Version 2.20, the self-extract executable will also recognize
and write to non-DOS diskette when running in an OS/2 session.

When running the 16-bit version of Disk eXPress under DOS and OS/2 1.x, the
automatic diskette detection logic will not detect diskettes with non-
standard number of tracks.  For instance, an 82 tracks diskette will be
detected as having 80 tracks; and therefore, the image file produced is
incorrect.  OS/2 versions of Disk eXPress will detect such non-standard
diskettes correctly if it is run under OS/2 2.x.


New Addition to Disk eXPress: VMDISKX
=====================================

Starting with Version 2.20, Disk eXPress includes an additional program
called VMDISKX.  VMDISKX performs the reverse of VMDISK for making the
Virtual Machine Boot diskette for OS/2 2.x.

Here is the help screen for VMDISKX:
