INTRODUCTION
We spent weeks searching the depths of the internet ftp sites for
a library that would allow the programmer full access to the
abilities of Super VGA. We wanted the colors VGA could provide
and better resolution than EGA could provide. Professionally
developed libraries with this ability were definitely out of our
price range. After our searches continuously returned nothing,
we decided to fill the apparent void in the shareware market.
Our searches did give two useful packages: John Bridges' VGAKIT
and Finn Thoegersen's VGADOC. We began with these two works and
developed a graphics library intended to allow the programmer
access to the huge world of high resolution programming.
On the surface the task appeared quite simple. However, it
quickly became obvious that the routines in this library would be
required to affect extremely large amounts of data. Operations
must be quick to be successful. Therefore, every effort was made
to create the fastest code possible - even at the expense of
size. For this reason we opted to write code with the 32 bit
instructions of the 80386 and better processors. It is our
opinion that anyone with a hi-res card in a lesser machine may
have some priorities out of order. All routines are written in
assembly and use absolutely no floating point values. Anytime a
real number was required, fixed point notation was used. In
addition we attempted to write the routines such that any
reasonable argument passed can be interpreted intelligently by
the library.
With the numerous Super VGA cards available and no well
established standard we chose John Bridges' identification and
bank switching routines as a beginning. These two routines have
undergone some modification, but not enough to justify
copyrighting this portion of the library's code by Zephyr
Software. We have no intentions of releasing our changes to
these routines into the public domain. From that point onward
all code is original. In some instances common algorithms were
researched and original code written according to that algorithm.
This Super VGA library gives the programmer transparent access to
twenty different Super VGA cards. These cards include Acumos,
Ahead, ATI Technologies, Avance, Chips and Technologies, Cirrus
Logic, Everex, Genoa, MXIC, NCR, Oak Technologies,
Paradise/Western Digital, Primus, Realtek, Trident, Tseng Labs,
Video 7 and the VESA standard. Please see the WHICHVGA function
for the specific chipsets. The programmer only needs to verify
that the end user's card has been identified, but not which card
was recognized. After proper identification, all functions react
in exactly the same fashion. The library contains functions to
draw all of the major primitives. In addition there are
functions that modify the screen palette, write text on the
screen with a choice of fonts and modify the reaction of the
primitives. Identification routines include not only the video
2
card, but also the amount of video memory, type of pro
