- V103f Installation Notes:
- =========================
-
- If you receive ZipStream as a Zip file, you should unzip all files
- to a diskette, as installation is designed to occur from diskette.
-
- After files have been unzipped to diskette, run 'view a:zstream.inf'
- for further information on installation.
-
- An alternative method is to unzip all files to a subdirectory say
- 'c:\zs' then change directory to that directory (cd \zs) and then
- run 'zsinst -s .' which specifies the source directory for the
- ZipStream installation program. After installation is complete you
- can delete the directory 'zs' e.g. del c:\zs\*.* and rd c:\zs.

- V103e New Features
- ==================
-
- V103e contains new compression and cacheing algorithms that
- significantly improve performance in cases where the existing algorithms
- have suffered.
-
- As with any compression or cacheing algorithm, there will always exist
- pathological cases where one algorithm will perform badly while another
- will perform well and visa versa. We have tried to ensure that the best
- performance is always achieved by using adaptive techniques, but even
- this can suffer in unexpected cases. For this reason we have still allowed
- manual selection of algorithms where appropriate.
-
- To utilize the new compression and cacheing options files will need to
- be recompressed into a new format. i.e.
-
- zsunpack *.*
- zspack *.*
-
- To give you an idea of the new performance possible here is some test
- results with AmiPro.
-
- AmiPro startup with no compression: 21 seconds
- AmiPro startup with old compression algorithms: 60 seconds
- AmiPro startup with new compression algorithms: 27 seconds

- Upgrading From Versions PRIOR to 1.03
- =====================================
-
- In Version 1.03 and later the storage path of several key
- components of ZipStream has changed.
-
- Previously most of the ZipStream files were stored in the \OS2 and
- \OS2\DLL directories. Now all files are stored in the \CBASED
- directory.
-
-
- Upgrading From Version 1.02 or later
- ====================================
-
- Just run a standard installation, the update operation is automatic.
- Then shutdown and restart to begin using the new version.
-
-
- Upgrading From Versions PRIOR to 1.02
- =====================================
-
- If you have a previous version already installed then follow these
- instructions:
-
- 1. Run the new zsinst utility manually as follows:
- zsinst -d
-
- (the -d switch is a new automatic deinstall function)
-
- 2. Reboot the system (Not Ctrl-Alt-Del)
- 3. Run the installation as per the on-line documentation
- (That is use the device drive install utility from the desktop).
-
- 4. Reboot, and that's it.
-
- Note: If you have modified the standard installation setup then you will have
- to manually deinstall ZipStream yourself, but try zsinst -d first!
-
-
- Deinstallation
- ==============
-
- Deinstallation is now automatic (if you have a standard installation),
- just run
- zsinst -d
-
- If you have a non standard installation, use zsinst -U to clean off the
- Desktop.
-
-
- Evaluation Period
- =================
-
- ZipStream may be evaluated for a period of 30 days only!
-
- After 45 days have expired, automatic (de)compression operations
- will be suspended.
-
- Files that are compressed on your system after the Evaluation period
- has expired may be manually decompressed with the ZSUnpack utility.
