TWEAK version 2

TWEAK makes it possible to run Windows 3.0 with 800x600
resolution with standard VGA cards, that are fully
compatible with IBM cards.

Here is procedure that can be used for this:
1. Make sure, that TWEAK is run before Windows is
started. There are many ways to do this: you can add
line
TWEAK
to your AUTOEXEC.BAT, or you can run it manually every
time. You can also make a batch that first runs TWEAK
and then Windows, but this causes TWEAK to be loaded
multiple times, if you start Windows more than once.

2. Run TWEAK for this time.

3. Install a Super-VGA 800x600, 16 colour Windows
driver. Probably most drivers work, but some may
require some tuning. First of all, the card for which
the driver is originally meant for, must be register
compatible with normal VGA. The driver must also use
BIOS for mode switching. The EMUL_MODE constant in
TWEAK.ASM must equal the video mode that the card uses
for 800x600 mode. The constant is preset to be
compatible with the Paradise SVGA driver. The software
is also tested with that driver, so it may be best to
use it.

4. Optionally patch the Super-VGA driver to use the
exact resolution used by TWEAK (800x564). This is done
by running PATCH with the name of the driver. E.g:
PATCH C:\WIN\SYSTEM\VGA800.DRV
PATCH is only tested with Paradise VGA driver. However,
it is a generic patch utility to be used for any
driver.
WARNING: PATCH might not be able to patch the driver
correctly. Test the modified driver thoroughly before
using it for important work.

By default, TWEAK actually only shows 800x564 pixels on
screen, since most monitors cannot handle the extremely slow
refresh rate that 800x600 causes. If you still want to try
800x600 mode, you can do that by including the commented
register values and by commenting out the used values.

If you need to change TWEAK.ASM, reassemble it with MASM.

I try to make a version of TWEAK, that allows the use of
752x564 mode. Currently the vertical resolution must be 800,
and this causes too much flicker on many monitors.
