Version 2.00 (8/22/93)
=======================
* It is no longer necessary to disable VGAsave from a batch file
before starting windows. VGAsave has been made windows aware.
Now VGAsave will detect that windows is coming on line and
automatically disable itself. VGAsave will remain disabled until
windows has been exited.
The windows detection may be enabled and disabled with two new command
line switches, /win_off and /win_on, respectively. The windows
detection may also be controlled from the interactive menu.
The status command (VGAsave /s) has been upgraded to show that VGAsave
has been disabled for MS-Windows. In the case that windows is active,
the status command will show "Saver: Disabled for MS-Windows". This
is different from the usual "Saver: Disabled" status message. When
VGAsave indicates that it has been disabled for MS-Windows, it cannot
be re-enabled until windows has been exited.
Thanks to Andy Charmatz for passing along some info from Steve
Gibson that made this upgrade possible.
* Upgraded the status command (VGAsave /s) to show the status of
the windows detection and the usage of the /int33 switch.
Version 1.93 (2/28/93)
=======================
* Added an interrupt 33h handler which may be used by starting VGAsave
with /int33 to resolve the mouse problems reported by several users
The interrupt 33h handler is not installed as a default since it
increases the resident memory requirement of VGAsave to 448 bytes.
See the section in the doc entitled "Mouse Problems" before using
the /int33 switch.
* The rstmouse utility is no longer needed with windows 3.0 and is
no longer distributed with VGAsave. VGAsave now will reset the
mouse each time /on or /m+ is used. This is necessary for the
int 33h handler to function properly.
* Special thanks to Eduardo L. Franco and Richard E. Roda for testing
the betas that never seemed to end. Without their help, the mouse
problem probably wouldn't have been resolved.
* Also thanks to Gene Ressler who independently confirmed the results of
my investigation into the interrupt 33h handler.
Version 1.92 (2/7/93)
======================
* This version was not officially released. Only a few pre-release
copies were mailed out. If you have version 1.92 or one of the
1.92 betas, download version 1.93.
* Added a /mirq switch that allows the user to manually specify the
IRQ line VGAsave is to use for the mouse. This allows VGAsave
better compatibility with older mouse drivers that do not report
the IRQ line used by the mouse via an int 33h call. But, you
have to have to get the mouse IRQ either from some memory mapping
software or from the mouse docs before you use the /mirq switch.
* If you have experienced problems with the mouse in the previous
version of VGAsave, make sure you read the section entitled
"Mouse Problems" in the doc file
* Added a /unblank switch to unblank the screen from batch files.
If you want you can now use 'VGAsave /now' to blank the screen,
run some program(s), and use 'VGAsave /unblank' to restore the
screen when done. This could also be useful at the command line
with DOS 5 i.e.
c:\>SlowProgram<ctrl-t>VGAsave /unblank
* Added more hot keys. Alt-A through Alt-Z, and Alt-0 to Alt-9 are
now possible hot keys for VGAsave.
* Looked into the possibilities of allowing VGAsave to recognize the
shift, alt, ctrl, etc... keys to unblank the screen. However, it was
found that adding this feature to VGAsave interferes with the hot key.
So, this was not and probably will never be implemented.
* Decreased the resident memory requirement of VGAsave slightly.
Version 1.91 required 368 bytes. Version 1.92 requires 352.
16 bytes is 16 bytes. :)
VGAsave 1.91 (8/4/92)
=====================
* Initial release.
Acknowledgements
================
I'd like to thank all the people who from the net who sent mail
describing the problems that they were having.
I'd also like to thank all the folks who dropped me a note saying that
they liked the program and everything was working fine.
