Well, you won't thank me for this...

There are no TIGA OS/2 drivers, and there never will be.  TIGA is
effectively dead; Texas Instruments have stopped further development
of TIGA.  As far as I was ever able to find out, no OS/2 TIGA drivers
were ever written.

At home, I have a Hercules Graphics Station (anybody want this?) with
a TI 34010 chip, and when I switched to OS/2 two years ago I went on a
fruitless hunt for drivers.  I eventually bought a new video card.

At work I had an Artist XJS, a 34020 card.  With 7M on the card, it
loaded and ran the entire X server itself (I was using Unix).  Then we
switched to OS/2, and the Artist card had to go; no TIGA drivers.

See, the TI 340x0 series is special because it's a fully programmable
CPU that happens to excel at graphics.  You get performance by
dibiding work between the two.  (The X Server was an excellent example
of how well this works - it was great, and I miss that performance.)

But these days, PC graphics hardware is defined by the set of
primitives that can be performed by a Windows video driver, and this
is a small, fixed set.  So the simple blitter accellerators have the
whole market now and TIGA has been abandoned.
