-* RVMODE13 V1.0 Readme *-




1.0 - Introduction

When I first got my Diamond Stealth II I was really impressed with it
particularly when you considered its price, but I soon noticed that some
things left quite a bit to be desired. The VGA mode 13 (320*200) performance
was really quite laughable.
Then I discovered that a VESA mode had the same properties but was 15
times faster and then I started thinking, "hmm, it would be great if I
could run my old games in the VESA resolution instead of the crappy mode
13". So I hacked this program together, saw that it worked, cleaned it up
a bit and here's the result.


2.0 - How it works

RVMODE13 hooks interrupt 10 which programs use to set mode 13. Whenever a
program requests mode 13, RVMODE13 will set up the much faster VESA mode
instead. This is done completely transparent to the program requesting
mode 13.


3.0 - How to use it

It really couldn't be simpler. Run RVMODE13 and then run the program you'd
like to have sped up.


4.0 - So, what's the downside?

First of all, the faster VESA mode is not VGA compatible. This means that
programs that set mode 13 and then tweak the VGA registers to achieve modeX
won't work properly. At best it'll look strange, at worst it will crash
horribly. Always save your work before using RVMODE13, particularly when
using it in Windows '95. For the same reason I don't recommend running
RVMODE13 in your autoexec.bat. Only run it when you have to.

Secondly, the refreshrate seems to be different. This is normally not a
problem but some programs might rely on the mode 13 refreshrate for
timing.


5.0 - What hardware and software does it work with?

Mine ;) Seriously though, I've tested it with my Stealth II, Quake (though
it can already use VESA) and Carmageddon.

There are only a few reasons why it shouldn't work on other Rendition
boards or indeed completely different cards.

Please let me know if it works (or doesn't) for you, both on your card and
with your software. I could then include the list in future releases.




Enjoy your Rendition card and feel free to give this little program to your
friends.
