- ==Getting More Information about Stacker
- ========================================
-
- Always Check Stacker Help!
- --------------------------
- Please note that Stacker Setup Help and the Stacker Help system in Windows
- contain up-to-date information about using Stacker.
-
- The easiest way to get detailed information about Stacker is to double-click
- the Stacker Help icon in the Program Manager and then click the Search
- button. Select or type in the name of the Stacker tool or procedure you need
- help on and select the topic. Stacker Help contains information on such
- topics as:
-
- - DPMS and Stacker in Memory
- - Stacker AutoSave
- - Compressing and automounting floppy disks
- - Repairing a damaged STACVOL file
-
- Stacker Help works with Windows 3.1. If you are using Windows 3.0, you can
- order a special version of Help through one of our online services. The
- product support brochure explains how to reach Stac's BBS or Stac on
- CompuServe.
-
- Use STAC FAX or STAC TALK for Special Topics
- --------------------------------------------
- If you have an unusual configuration or are interested in specific advanced
- Stacker topics, you can order information from our STAC FAX STAC TALK
- system. Both services are available in the U.S. and Canada 24 hours, 7 days
- a week. See your technical support brochure for information on how to reach
- STAC FAX or STAC TALK. For a listing of STAC FAX topics, request STAC FAX
- #1000.
-
- ==Getting the Best Compression
- ==============================
- If you are upgrading from a previous version of Stacker, be sure to choose
- Full Update when you run Stacker Setup. The Full Update option updates your
- compression to Stacker 4.0's new storage format. Depending upon the size of
- your disk, Full Update may take a few hours. If you upgraded Stacker but
- didn't perform the Full Update, search for the topic "Updating Stacker
- drives Outside of Setup" for more information on updating your drives.
-
- ==Additions/Changes to the User's Guide
- =======================================
-
- Please note the following changes and/or additions to your User's Guide:
-
- Page 8--If you are using MS-DOS 6.2, Stacker runs SCANDISK instead of CHKDSK
- while converting DoubleSpace drives to Stacker drives.
-
- Pages 28-30--Stacker Anywhere is designed for use on computers that do not
- have Stacker installed. If you are using compressed floppy disks on a
- computer with Stacker, you do not need to use Stacker Anywhere. But you do
- need to change your configuration so that Stacker will automatically mount
- floppy disks you compress using the Stacker Toolbox. To have Stacker
- automount your B drive, for example, completely exit to DOS. Then, type
- C:\STACKER\ED and choose STACKER.INI from the File menu. Add the line B: on
- a line by itself. Restart your computer. From now on, Stacker automatically
- mounts a Stacker-compressed floppy disk you insert in the B drive.
-
- Page 29--The Note at the bottom of the page describes a procedure for
- viewing compressed data on a removable disk under both DOS and Windows. To
- do this, you need to type STACKER d: where d: is the drive letter. If you
- type STACKER without the drive letter, a listing of all your drives
- displays.
-
- Page 48--The last paragraph asserts that Stacker sets up your configuration
- to automount when you compress a floppy disk in that drive. This is true
- only if you compress the disk through Stacker Setup. If you compress the
- floppy disk through the Windows Toolbox (using the Compress tool), add
- either an A: or a B: (or both) to your STACKER.INI file and restart your
- computer. Changing your configuration in this way sets up automounting for
- the floppy disk drive.
-
- ==Compatibility and Other Issues
- ================================
-
- Third-party disk optimizers
- ---------------------------
- Disk optimizers other than the Stacker Optimizer are not effective on
- Stacker drives. Please do not use optimizers such as Norton Speed Disk 7 or
- PC TOOLS PRO 9.0 for DOS after you've set up Stacker on your system.
-
- Norton Disk Doctor 7.0
- ----------------------
- Unfortunately, Norton Disk Doctor 7.0 is not yet compatible with Stacker 4.0
- drives. If you are using NDD 7, please check the option to "Skip Compression
- Tests."
-
- QEMM 7.x
- --------
- If you are running a version earlier than QEMM 7.03, please consider
- upgrading to the latest version. For QEMM 7.01, please add the option
- /B=2001 to the DEVICE=DOSDATA.SYS line in your CONFIG.SYS file. In all
- versions of QEMM, at startup, the DOS-UP feature (DOSDATA.SYS) temporarily
- disables your monitor and Stacker's password prompt. In your CONFIG.SYS
- file, add the option: DEVICE=DOSDATA.SYS /ALTVIDEO- so the password prompt
- is visible again.
-
- QEMM Stealth mode and DOS 5
- ---------------------------
- In Stacker's Custom Setup, please choose the "Don't Use EMS" option if you
- are using QEMM's Stealth mode. Stealth mode cannot access memory using EMS.
- In Stacker's Express Setup, the default is to "Use EMS" if your computer
- uses 32K clusters (large drives) or if you cannot use DPMS. In these cases,
- insert the option /DBF=2 on the QEMM386 line of your CONFIG.SYS file.
-
- DPMS and 386 Max
- ----------------
- To take advantage of DPMS and reduce your memory requirement, please add the
- switch EMS=0 to your 386MAX.PRO file.
-
- PKZIP 2.04
- ----------
- If your computer takes advantage of Stacker's DPMS (386 or higher with 1MB
- of RAM), please use the -) on the command line when using PKZIP 2.04. These
- options disable PKZIP's use of a DPMI driver that interferes with DPMS. If
- you want to permanently disable DPMI, add one of these options to your
- PKZIP.CFG file.
-
- DOS Screen Savers and Stacker Optimizer
- ---------------------------------------
- Before running the Stacker Optimizer, disable the DOS mode of screen savers
- such as AfterDark. They interfere with Stacker Optimizer completing its work.
-
- Speeding Up AutoSave
- --------------------
- To speed up the time it takes Stacker to save header information at startup,
- edit your AUTOEXEC.BAT file. Move the line C:\STACKER\CHECK /WP so it comes
- after the SMARTDRV.EXE line.
-
- Stacker for OS/2 & DOS
- ----------------------
- Please do not install Stacker 4.0 on a system that is using Stacker for OS/2
- & DOS. If you do, you won't be able to see your compressed DOS drives under
- OS/2. Stacker for OS/2 & DOS does not yet take advantage of Stacker
- SmartPack. If you want to install Stacker 4.0, you'll have to first remove
- Stacker for OS/2. First use the UNSTACK command to decompress your data.
- Then, remove the OS/2 Stacker driver STACKER.SYS and its associated files
- from their directory (usually C:\STACKER\OS2). Then you can set up Stacker
- 4.0.
-
- Backing Up a Stacker Drive
- --------------------------
- You can perform your standard backup procedure to back up files on the
- Stacker drive. If you also want to back up the files on the uncompressed
- drive, backup all files EXCEPT the hidden STACVOL file. (The STACVOL file
- actually contains your compressed data.) Type STACKER at the DOS prompt to
- determine the location of your STACVOL file. The location of the STACVOL
- file will be in [brackets]. For example, on a computer with C as the Stacker
- drive, the uncompressed drive is typically D [D:\STACVOL.DSK = size]. You
- would back up all the files on drives C and D except the file STACVOL.DSK.
-
- Adding a Hard Disk
- ------------------
- When you add another hard disk to your system, DOS assigns it the next
- available drive letter, usually D. The Stacker drive that previously swapped
- with drive D now swaps with drive E. Stacker takes care of the drive letter
- assignments so you still find your data on drive C. If your new hard disk
- requires a device driver, place the hard disk device driver BEFORE the
- STACKER.COM and/or STACHIGH.SYS statements in your CONFIG.SYS file.
-
- Stacker Optimizer and 32K Cluster Drives
- ----------------------------------------
- If you are using drives with 32K clusters, Stacker Optimizer may need
- additional memory (more than the 600K needed in previous Stacker versions).
- If you don't have that much conventional memory available, you can run
- Stacker Optimizer with a special option. Using this option affects speed,
- but allows you to run in less memory.
-
- To run Stacker Optimizer in less memory:
-
- 1. From the DOS prompt, type SDEFRAG /buffer=#
-
- where # is a value between 256 and 4096, inclusive
-
- The following examples show how much memory is saved with various values:
-
- SDEFRAG /buffer=3072 21K memory saved
- SDEFRAG /buffer=2048 42K memory saved
- SDEFRAG /buffer=256 78.75K memory saved
-
- By default, SDEFRAG normally runs at /buffer=4096.
-
- ==Upgrading from Stacker 1.x to Stacker 4.0
- ===========================================
-
- Before you upgrade from Stacker 1.x:
-
- 1. At the DOS prompt, type SWAPMAP and press ENTER to determine which drive
- letter is being swapped with C. Write that letter here.________________
-
- 2. Insert Stacker 4.0 floppy disk #2 into its drive.
-
- 3. Type
-
- drive:SATTRIB -R C:\AUTOEXEC.BAT
-
- where drive: is the letter of the floppy drive where you inserted floppy
- disk #2. This removes the read-only attribute from the AUTOEXEC.BAT file.
-
- 4. Type
-
- COPY drive:\AUTOEXEC.BAT C:\
-
- where drive: is the drive letter in which C is being swapped
- (determined in step #1).
-
- 5. Type
-
- COPY drive:\CONFIG.SYS C:\
-
- where drive: is the drive letter in which C is being swapped
- (determined in step #1).
-
- 6. Install Stacker 4.0 starting with Disk 1.
-
- If you are using DOS 5 or an operating system that does not preload
- compression, you need to add the /SYNC+ option to your STACKER.INI file to
- synchronize configuration files on compressed and uncompressed drives. (From
- the Stacker directory, type ED to start the editor. Then, choose STACKER.INI
- from the File menu. Add the /SYNC+ on its own line anywhere in the file.)
