- 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.
-
-
- For the Future
- ==============
-
- If I could ever find out what int 2fh call windows makes when it
- starts and ends (if it does use an int 2fh call), I would like
- to have VGAsave recognize that windows is coming on line and automatically
- disable itself and re-enbale itself upon return to DOS.
-
- Anybody have ideas or sources of documentation to make VGAsave windows
- aware?
-
- I dunno. Maybe it would be best just to leave VGAsave the way it
- is since this will increase the resident memory requirement, /off
- and /on work fine.
-
-
- 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.
