- DCF/2 Disk Compression Facility for OS/2 Version 1.1b
- Introductory and Installation Notes
- ═══════════════════════════════════════════════════
-
-
- The DCF/2 is an "on-the-fly" disk compression facility which
- allows you to increase the effective data storage capacity of
- your OS/2 computer system.
-
- DCF/2 Virtual Disk Units, or VDUs, are formatted using the
- OS/2 High Performance File System (HPFS). An HPFS-formatted
- drive is faster and more efficient than the equivalent size
- FAT (File Allocation Table) formatted drive. But most
- importantly, you can use the DCF/2 to create and use HPFS
- formatted drives ON TOP OF ANY EXISTING type of OS/2 disk
- drive, including FAT, HPFS, FLOPPY -- even LAN logical disk
- units!
-
-
- ═══════════════════════════════════════════════════
- 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.
-
- IMPORTANT: If you are running a version of OS/2 prior to 2.11,
- the HPFS is 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
- 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 hpfs.ifs to that
- level. The installation program does not check OS/2 versions.
-
- OS/2 files 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.

- 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 you will run the DCF/2
- programs. You will also enter on this screen the "Total
- VDUs" to create. 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, DESKTOP objects, and exit.
-
-
- IMPORTANT NOTE:
-
- If you are updating an existing DCF/2 1.1a installation, please
- refer to the Appendix in the online help -- before you start the
- install program -- for the steps to follow in order to convert
- your existing VDUs to 1.1b format.
-
-
-
- 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.
-
- 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 these accidentally.
-
-
- ════════════════════════════════════════════
- Rebooting Your System
- ════════════════════════════════════════════
-
- During the final part of the installation process, the
- program will place the DCF/2 Shutdown icon on your desktop and
- 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.
-
-
- ════════════════════════════════════════════
- When the DCF/2 Sings . . .
- ════════════════════════════════════════════
-
- The DCF/2 is "audio-enabled." These audible beeps inform you
- when certain events are taking place, e.g., when the DCF2ACP
- is "armed" of "disarmed," when the space manager program
- updates a VDUs DCF2INFO.CMD, or when an error occurs, like
- a failure on a lock to shared memory.
-
- But when the DCF/2 REALLY sings, it means that this copy
- of the DCF/2 is unlicensed. It is our gentle reminder to
- the user that the DCF/2 is neither freeware nor shareware.
- We want you to have an opportunity to "evaluate" the DCF/2.
-
- After you have completed your evaluation, we ask you to
- either remove the software from your system or purchase a
- licensed copy of it. Order information is included in the
- REMINDER.LOG file in the root of your OS/2 boot drive.
