- 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
- ---------------------------------------------------
-
- If you are upgrading from a previous version and have used QEMM's
- OPTIMIZE program to load SCSAVER into a specific UMB region, it is
- recommended you rerun OPTIMIZE after installing SCSAVER 5.1.
-
- 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.
-
- 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 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 5.1
- ====================================================
-
- Screen Saver now supports the Hercules monochrome graphics cards.
- Detection of these cards is automatic when the card is installed.
-
- The new /F: option in SCSAVER.COM will allow the name and path of
- the option file (SCSAVER.DAT) to be specified on the command line.
- Other programs such as SCSAVPSW and SCSAVINS will now accept the name
- of the option file on the command line.
-
- The new /S:nnn option in SCSAVER.COM will allow the you to specify
- how sensitive Screen Saver is to mouse movement when determining
- inactivity. Setting this to a non-zero value can prevent Screen
- Saver from restoring the screen when the mouse moves slightly (like
- when your desk is bumped).
-
- The new /A:nn option in SCSAVER.COM can be used to limit the number
- of incorrect password attempts after the lock has engaged.
- Specifying zero will allow unlimited unlock attempts.
-
- The new /T+, /T- option in SCSAVER.COM replaces the /VTRAP option of
- SCSLOAD.EXE and extends this functionality to the resident monitor.
- This makes it no longer necessary to load programs with SCSLOAD in
- order to use the vector trapping capability of /VTRAP and allows
- vector trapping to work with TSR programs.
-
- A new program has been added to enhance security. SCSLOG.COM is a
- TSR (terminate-stay-resident) event logger that will record various
- events, such as when the lock has engaged, attempts at entering a
- password, changes to the resident parameters, etc.
-
- Screen Saver will now handle 3-button mice, as long as they use a
- Microsoft-compatible mouse driver. It also correctly handles the
- Borland Turbo Debugger mouse calls.
-
- SCSAVER will now only reload the default options when the /F (or
- /F:name) switch is specified. Previously, it would reload the
- default options if executed without command line parameters. Default
- options are still loaded (and merged with any command-line
- parameters) the first time SCSAVER is run.
-
- The program SCSCGA.EXE has been added to correct a problem on older
- CGA and MDA screens. Under DOSSHELL (or any program which uses
- high-intensity characters), Screen Saver may cause the screen to be
- restored blinking. This can be prevented by running SCSCGA in the
- AUTOEXEC.BAT following SCSAVER.COM.
-
- The resident monitor (SCSAVER.COM) will now aggressively take-over
- the keyboard interrupt when the lock engages. This will insure that
- the user is allowed to enter the password to unlock the system, even
- when running terminal emulation and game programs that do not
- correctly cascade the keyboard interrupt.
