- EGAUTIL 8.5 - (c) Kai Uwe Rommel - Nov 21 1990
-
- This is the third public release of EGAUTIL & EGAWUTIL. The name may
- imply that it is a utility for EGA only, but it works on VGA as well.
- In reality, VGA cards are recognized and handled a bit different.
- The name is just for historical reasons (see version number ...).
-
- This is a screen saver on which I am working already for a long time.
- It runs on EGA or VGA under DOS and has some special features. It
- monitors not only the keyboard but also a Microsoft-compatible mouse,
- if installed (compatible on driver level, Logimouse was tested with an
- earlier version). Also, it can blank a secondary monochrome Hercules
- display, if installed. See its help page for details.
-
- Now I added a small DLL for use under Windows. This DLL establishes a
- system hook and notifies the screen saver of Keyboard and Mouse events.
- They communicate via the multiplex interrrupt (INT 2F). This DLL works
- under Windows 3.0 or newer only (in all three modes, real, standard and
- 386 enhanced). The INT 2F seems to be clean to be called in protected
- mode, even in 286 standard mode (the INT 2F is the preferred method for
- communication with TSR's under DOS anyway). Without this DLL loaded, the
- screen will never be blanked in standard or enhanced mode.
-
- I have tested it under Windows 3.0 with heavy load and it always worked
- well. But if you have problems with it, please reportthem to me. Note
- again: IT ONLY WORKS WITH EGA OR VGA (all Super VGA too).
-
- The screen is blanked by completely switching off the display(s). That means
- if you would like some pictur/graphics/animation, then this one is not
- for you ..., but this has the advantage, that all the Windows do not have
- to be repainted, when the screen is switched back on.
-
- I wanted the screen (and the monochrome debugging display) to be
- *completely* blanked. I find these animated screen savers boring after a
- while - so I wrote one that is boring from the beginning :-)
-
- When running Windows with EGAWUTIL.EXE, if the mouse is moved into the upper
- right corner of the display, the screen is blanked instantly. If it is
- moved into the lower right corner, the screen will never be blanked.
-
- When running plain DOS without Windows, the screen can be blanked manually
- by pressing Sys-Request (Alt-PrintScreen) and then the key S (short clicks
- are heard when pressing these two keys).
-
- Install the screen saver main program EGAUTIL.COM in AUTOEXEC.BAT with
-
- EGAUTIL /I /D:delay [/M] [/2]
-
- The delay is in minutes, /M means a mouse is installed (probably you all have
- one), /2 means a secondary monochrome display is installed.
-
- Put the EGAWUTIL.EXE into WIN.INI into the "Load=" line
-
- Load=EGAWUTIL.EXE ...
-
- (You perhaps have more programs listed in this line).
