DCF/2 Data Compression Facility for OS/2 Version 1.4c
Introductory and Installation Notes
══════════════════════════════════════════════
The DCF/2 is an "on-the-fly" data compression facility which
allows you to increase the effective data storage capacity of
your OS/2 computer system.
If you have used traditional "on-the-fly" data compression
products -- get ready! The DCF/2 is unlike anything you've
used before. You don't need to commit yourself or your
entire system to data compression in order to try it.
No repartitioning or formatting of your existing hardware
is required. Our compressed drives grow dynamically as
you move data onto them.
While they are always formatted using OS/2's High
Performance File System, they can sit ON TOP OF ANY
EXISTING type of OS/2 disk drive, including
FAT, HPFS, FLOPPY -- even LAN logical disk units!
You can create your first DCF/2 compressed drive (called a
"virtual disk unit" or VDU) of whatever size you choose
(not limited to what you have available on your disk) --
even if your disk is down to its last 10 megabytes.
If all this sounds a bit intimidating -- don't let it. HELP
is always available at the stroke of a key <F1>. Select
from the contents or enter a text string and use the SEARCH
function.

═══════════════════════════════════════════════════
The DCF/2 and OS/2 Version Support
═══════════════════════════════════════════════════
This version of the DCF/2 allows you to create as many
virtual disk units as you have drive letters available. You
can 'put' those VDU's on any of your existing disk units as
long as you are running OS/2.11 or OS/2 Warp.
If you are running OS/2 Warp and the High Performance File
System is not installed, you must exit the DCF/2 install
program and use OS/2's SELECTIVE INSTALL feature (plus
your OS/2 disks) to install the HPFS. (It isn't difficult
and requires only a few minutes.)
IMPORTANT: If you are running a version of OS/2 prior to 2.11,
HPFS hosts are not supported. Place DCF/2 compressed drives
only on FAT-based devices -- do not place DCF/2 compressed
drives on your HPFS formatted partitions if running a version
of OS/2 previous to OS/2 2.11 (OS/2 2.1 plus the Service Pak).
To order OS/2 2.1 Service Pak, call IBM at (800) 494-3044.
If the High Performance File System is not installed on your
OS/2 2.11 system or the date-time stamp on the HPFS.IFS in
your OS/2 directory is earlier than April 19, 1994, the
install program will automatically update your system's
HPSF.IFS to that level.
The OS/2 files included on the DCF/2 distribution disk are
being provided on behalf of IBM for maintenance
purposes only and the rights and licenses to these files are
governed by the terms and conditions of the end user's OS/2
product license agreement.
We are grateful to IBM for having allowed us to include OS/2
files for these purposes on the DCF/2 distribution diskette.

INSTALL.EXE README.14 PKUNZIP2.EXE
HPFS211.ZIP PSCPRD.INF
═══════════════════════════════════════════════════
The DCF/2 Installation Program
═══════════════════════════════════════════════════
The "DCF/2 Installation" screen asks you to select the
"Target Drive" for the DCF/2 program files. This is the
uncompressed drive from which OS/2 will run the DCF/2
programs. You will also enter on this screen the "Total
VDUs" to create. (Don't worry, this number can be
changed at a later time.)
If you are uncertain how many VDUs to create or what size to
make them, please depress the "HELP" button or push "F1" and
click on the "Installation" topic.
IMPORTANT NOTE:
IF YOU ARE USING LAN-DEFINED DISK DRIVES,
STOP YOUR LAN OR UNDEFINE THOSE DISK UNITS
BEFORE CONTINUING WITH THE DCF/2 INSTALLATION!
If you are updating an existing DCF/2 1.1b or later, simply
click on the check box to "Update/Register Only" on the
"DCF/2 Installation" menu. The program will update your
existing DCF/2 program files, update your CONFIG.SYS file,
DESKTOP objects, and exit. If you prefer, you can run a
full installation and use the program to create additional
virtual disks without over-writing those you are already
using.
IMPORTANT NOTE:
During the next part of the installation you create each of
your VDUs. The first VDU you create will take the first
available drive letter on your system; the second will take
next available drive letter, and so on up to the total number
of VDUs you requested be created. If you have defined LAN drives
on your system, and you have not done so, be sure to logoff of
the network prior to creating your first VDU.
For each VDU, you select the drive letter for the "Host
Physical Unit for VDU" and the "Total Size in MB." The
"Host Physical Unit" is where the VDU container file is
stored. The "Total Size" is the total capacity OS/2 will
believe the drive has. (It helps to think in terms of
the number of megabytes of files you want the VDU to hold
when it is full.) If you are uncertain as to how large to
create your new DCF/2 Virtual Disk Units, press F1 (for
Help) and use the Search function to Search All Sections
for "size".
Having indicated your choices, you can now "Create or Update
VDU," get "Help," or "Exit/Cancel." The latter allows you
to change your mind or correct an unwanted choice.
Following the successful creation of your first VDU, the
process repeats itself for each subsequent VDU up to the
total number of VDUs you requested.
Once your VDUs have been created, the DCF/2 program files
are copied to the "Target Drive," and the program creates
the CONFIG.DCF file. This file will replace your existing
CONFIG.SYS file after you existing CONFIG.SYS file is saved
as CONFIG.!D!
You can choose not to have the DCF/2 installation program
update your CONFIG.SYS, but you MUST complete this part of
the installation process on your own in order to use your
compressed drive(s).
════════════════════════════════════════════
Changes to Your System Configuration File
════════════════════════════════════════════
The changes made to your CONFIG.SYS file will always be
delimited by lines and REM statements which explain what
was changed and when the change was made. The best way to
understand how this is done is to look at your CONFIG.SYS
file after your system has restarted.
The REMed delimiting lines can be deleted at any time should
you choose to so do, but do exercise caution so as not to
delete more than intended accidentally.
════════════════════════════════════════════
Rebooting Your System
════════════════════════════════════════════
During the final part of the installation process, the
program will display the DCF/2 README file. It will then
ask if you would like to restart your system at this time.
The changes to your CONFIG.SYS are initialized only after
your system is restarted.
════════════════════════════════════════════
Unlicensed Copies of the DCF/2 . . .
════════════════════════════════════════════
Unlicensed copies of the DCF/2 are available on a variety
of online services as a way to allow people to see how
the product works and to encourage them to buy it. These
have a "life" -- during which they are identical to the
current shipping version of the software for only a two
to three months. After that, they are no longer current.
If you download a version you suspect is out of date,
please inform the local sysop that it should be removed
and replaced with the most current test-drive version.
To order a copy of the most recent test-drive or full
version of the DCF/2, contact us at:
