MODSAV 1.00
Summary
-------
If you use custom screen fonts or more than 25 lines on a VGA, you may
find that many applications reset to the standard ROM font or to 25
lines for no apparent reason. MODSAV should reduce the frequency with
which this occurs.
Installation
------------
To install MODSAV, simply type
MODSAV
at the DOS prompt, or include it in a batch file (such as AUTOEXEC).
MODSAV will load and remain resident, using about 250 bytes of memory.
Enabling/disabling
------------------
After MODSAV is loaded, you can temporarily disable it by executing:
MODSAV /D
It can later be re-enabled via
MODSAV /E
Remarks
-------
VGA adapters are designed to permit custom RAM-based screen fonts; they
can also use a wide variety of screen sizes: 25, 28, 30, 33, 44, 50,
and even more lines (personally, I like 33--with the right font, it's
quite readable, and the extra eight lines are useful).
One common problem is that many applications reset the video mode when
they start up; this has the effect of restoring the default screen font
and the standard screen size. This has led to such unusual solutions as
fonts with which resident code is associated, allowing the fonts to be
reloaded via a hot key after an applications has unloaded them. A nicer
solution--and one that uses much less memory--is to simply suppress mode
resets when the video system is already in the requested mode--and that
is what MODSAV does.
Once loaded, MODSAV watches all requests for video mode resets and
discards requests that duplicate the current mode. For example, if a
program requests 80-column color text mode and the VGA is already in
that mode, MODSAV simply ignores the request and returns to the calling
program (with your RAM font and screen size intact).
