I have done a Truevision Targa video board driver
for ISC 386ix v2.0 (V.3.2).
The driver maps a 64k chunk of memory from the display card to
the users virtual memory and diddles a few I/O ports.
I will shortly be porting this driver to Xenix.
If I remember correctly this will be a 386 v2.3.x.
What documentation is available for writing such a driver
and how does one get it?
