ATI EGA wonder emulatie - HOW does it work

[Honzo Svasek]

It seems that there are ATI EGA Wonder users on the net. My original
question was How This Works. 

I have a non-ms-dos-os (VentureCom Venix), and want to use the ATI card
on it in emulation mode. It worked fine with the Venix 2.1, but with the
latest release (2.3) Venix knows about EGA, and it does not work with
the ATI anymore.

I have the Venix driver sources, and would like to debug them :) so
they work with the ATI card.

ATI has send me their "programmers diskette", and with this I can get the
parameters to put the EGA Wonder in different modes without using their
bios. But they also told me that the emulation mode won't work with os's
that do not use the bios such as Xenix, uPort, Venix etc.

I still want to use this mode, and am looking into how they do it.

Any EGA guru's out their that good give the answer, or tell us they
direction to search in?????
