*** SySwitch 2.03  *** 

SySwitch is designed to make it easy to switch
between up to five alternative SYSTEM.INI file
configurations. You might, for instance, have
alternative SYSTEM.X files for use with different
screen drivers or different Windows shells.

SYSWITCH.EXE and SYS2.TXT should both be placed
in your WINDOWS directory.

Before you can put SySwitch to use, you'll
have to create the alternative SYSTEM.INI files that
you'll use with it, copying your current SYSTEM.INI
to them, making the changes that you want, and
then giving them names like
SYSTEM.800 for a version of SYSTEM.INI that
uses an 800x600 video driver, or SYSTEM.NDW
for a version that uses Norton Desktop as the
Windows shell.

Next, run SYSWITCH.EXE and select the Configure
option on its file menu. Select the alternative
driver that you want to change on the drop down
list box (all five alternatives will read
"Default" the first time you run SySwitch.
Then use the edit boxes below to enter a name for
your alternative configuration, and to designate 
the name of the SYSTEM.INI alternative that it
should use.

For instance, you might name one alternative:
Norton Desktop, 800x600x16 display
and identify SYSTEM.NOR as the configuration file.
SYSTEM.NOR would be a copy of your standard SYSTEM.INI
file in which you'd changed

SHELL=PROGRMAN.EXE
to
SHELL=NDW.EXE

and

DISPLAY.DRV=VGA.DRV
to
DISPLAY.DRV=VGA800.DRV.


You should create these alternative files prior to 
attempting to use them with SySwitch.

Once you've made your changes on the File Configure
screen, click OK to save them (SySwitch saves
its own configuration information in a file
called SYSWITCH.INI in your Windows directory)
or Cancel to abandon the changes.
When you press restart, SySwitch deletes SYSTEM.BAK,
renames SYSTEM.INI SYSTEM.BAK, copies
the specified configuration file to SYSTEM.INI,
and then restarts Windows.

In addition, per the suggestion of Costas Kitsos,
the current version of SySwitch accepts command
line parameters. Thus, you can create a Program
Manager or Norton Desktop icon for it that
automatically restarts Windows using the system
file specified on the icon's command line. For 
instance, if you launched SySwitch 2.0 with
the command line:

SYSWITCH.EXE SYSTEM.102

It would look for the file System.102 in your
Windows directory and use it to restart Windows.
The file specified on the command line must be in
your Windows directory, SySwitch will not look
elsewhere for it even if you specify another
directory.

Whether you use a command line parameter or select
from the list of alternative configuration files,
the configuration file that SySwitch uses to restart
Windows must be a valid SYSTEM.INI-type file, or 
Windows will not run. SySwitch does some testing
to ensure that the specified file exists. However, 
it is undoubtedly possible to fool
SySwitch into attempting to restart Windows with a
non-existent or invalid configuration file. If
this happens, and you are unable to start Windows,
copy SYSTEM.BAK to SYSTEM.INI to restore your
previous configuration.

Many of the routines used here were borrowed from
other applications available on the MSBASIC forum.
Specifically, the CopyFile routine was described in 
the VBTIPS.TXT file, the 3-D framing routines are 
variations of one used by the VBTIPS reader,
and the RestartProc routine is detailed in the
MOREAPI.MAK file. Sincere thanks to the authors of 
each routine.
