- II. PRODUCT INSTALLATION
- ========================
-
- If you received the product from Compuserve or a Bulletin Board
- System, you most likely received an archive file or self-extracting
- archive. You should unpack this file using the appropriate
- unarchiving program (PKUNZIP, LHA, etc). If the file is
- self-extracting (that is, has a .EXE extension), you should run the
- program to extract the individual files.
-
- When the product is distributed on disk (for example, when registered
- users receive upgrades), an install program is included and may be
- used to simplify installation. In the examples below, it will be
- assumed that the floppy drive is drive A:.
-
- (Place the distribution disk in drive A:)
- A:
- INSTALL
- (Follow the instructions shown)
-
- If you have a monochrome monitor attached to a color adapter (or an
- LCD laptop), you may type INSTALL /MONO to force the displays into
- monochrome.
-
- If you do not wish to use the INSTALL program, you may extract the
- files manually by running the program UNPACK.EXE and specifying the
- names of the .LZH files to be unpacked. For example:
-
- A:UNPACK A:*.LZH
-
- After installing or unpacking the product, you should print the
- manual, SCSAVER.DOC, and follow its instructions for setting up and
- running Screen Saver. To print the documentation, type the following
- at the DOS prompt:
-
- COPY SCSAVER.DOC PRN
-
- Print is formatted for 8.5" x 11" paper.
-
-
- III. UPGRADING
- ==============
-
- Note to QEMM users who have OPTIMIZEd their systems
- ---------------------------------------------------
-
- Screen Saver has become somewhat larger. If you are upgrading from a
- previous version and have used QEMM's OPTIMIZE program to load it
- into a specific UMB region, it is recommended you rerun OPTIMIZE
- after installing SCSAVER 5.0.
-
- SCSAVER.DAT conversion:
- -----------------------
-
- Be sure to run the setup program SCSAVINS.EXE to resave your option
- file. If you do not need to change any of the options, the /SAVEONLY
- command-line switch will cause the option file to be resaved without
- intervention.
-
- New password handling procedure:
- --------------------------------
-
- The method Screen Saver uses for handling passwords when the
- security lock has engaged has been changed. If you use the security
- lock feature, please read item 3 in the next section for a complete
- description of the new method.
-
- Users of the MS-DOS 5.0 shell and task switcher (DOSSHELL) program
- ------------------------------------------------------------------
-
- The DOSSHELL, included with MS-DOS 5.0, issues a video interrupt when
- updating its on-screen clock. This will cause Screen Saver to reset
- its count-down timers unless it was loaded with the /V- option.
-
- Screen Saver now supports the MS-DOS 5.0 Task Switcher API and will
- cooperate to restore mouse monitoring between task switches.
-
-
- IV. SUMMARY OF NEW FEATURES & CHANGES - Version 5.0
- ====================================================
-
- File handles for Standard Input and Standard Output are now closed
- before Screen Saver goes resident. This allows all screen output to
- be redirected using the ">" and "|" symbols during initial loading.
- You may wish to use this instead of the /Q option to suppress load
- messages.
-
- A screen showing current resident parameter and option settings is
- now displayed in addition to the help screen when the "/?" option is
- specified.
-
- Password handling has changed considerably. A carraige return is now
- required in order to validate the password input. In addition, if an
- incorrect character is typed, you must press return before attempting
- the next password. This change prevents words like "SLOW", "LOW" and
- "LOWS" from being treated as identical.
-
- After the correct password has been entered, a short "beep" will
- sound indicating success.
-
- The /C+ and /C- command line (or setup) options will allow the case
- of alphabetic letters to be respected or ignored. For example, with
- /C+, "SLOW" and "Slow" are considered different. With /C-, they are
- considered matching.
-
- The LOCKNOW command-line parameter has been added. Running SCSAVER
- with this parameter will allow the security lock to be activated from
- a batch file.
-
- When the security lock engages, Screen Saver will prevent the
- Desqview menu and/or the DOS 5.0 Task Switcher menu from being popped
- up and will prevent switching windows or tasks. Also, mouse activity
- will be disabled while the security lock is engaged.
-
- Screen Saver now allows a "Master Lock Hot Key" to be defined
- independent of the "Screen Blanking Hot Key". Pressing the Master
- Lock Hot Key, if defined, will invoke the security lock no matter
- which mode Screen Saver was loaded with. The "Screen Blanking Hot
- Key" will still function as before. That is, SCSAVER must have been
- run with the LOCK or LOCKONLY keyword in order for the Screen
- Blanking Hot Key to also invoke the LOCK.
-
- When Screen Saver is loaded into a Upper Memory Block (UMB) by either
- DOS5, 386^MAX or QEMM/QRAM, the environment block will be released.
- This can conserve memory which is particularly at a premium in the
- UMB area.
-
- Users with severely memory-constrained systems may reduce the
- resident size of Screen Saver by omitting the mouse support code. If
- you do not have a mouse driver, this will happen automatically. If
- you DO use a mouse driver and need to conserve memory, loading
- SCSAVER with the /M- switch will omit the mouse support code and save
- approximately 800 bytes. If Screen Saver has been initially loaded
- without the mouse support code, you will need to reboot in order to
- activate mouse support.
-
- A new program has been added. SCSREMOV will remove the resident copy
- of Screen Saver. In order for this program to work, SCSAVER must be
- the last program loaded and no other programs may have hooked the
- interrupts used by Screen Saver.
-
- Documentation has been added for Screen Saver's application
- programming interface. This interface allows user-written programs
- to communicate with resident Screen Saver. (See file SCSAVER.API for
- details).
-
- The program SCSAVINS is now referred to as the "setup program" in the
- documentation.
-
- SCSLOAD now accepts options /ON, /OFF, /LOCK and /LOCKONLY. These
- correspond to the SCSAVER ON, OFF, LOCK and LOCKONLY parameters and
- may be used to temporarily override Screen Saver's state.
-
- SCSLOAD has a new local option /VTRAP. This option sets a vector
- trap which can be used when loading some ill-behaved programs that
- intercept the keyboard interrupt and don't cascade as they should.
- Using /VTRAP allows most of Screen Saver's features to work, although
- you may find that its hot-keys are disabled.
