I wrote a Bt848 driver for a customer . If you like just e-mail me.
Now Brooktree is supposed to have a driver development kit
or a fully functional driver with sources for Win95 and
when WDM gets release it will also work for NT 5.0. 

As to how I wrote the video portion of the driver ?
Just read the databook and a lot of hardwork mostly
because the databook falls very shy of being a damn
good databook. It would have a help a lot for instance
to provide an actual example on how to generate the
microcode. After I wrote the driver and had a few more
questions I contacted Brooktree and they sent me a 
dos kit which is okay however I felt it was somewhat lacking.

I forgot... Microsoft has a WDM Bt848 driver with sources
which is supposed to work for Win97 and Win NT 5.0. Last
I check the WDM stuff is not complete for Win XXX..

At any rate, feel free to send me e-mail if you like
for further discussion. Not too keen on discussing 
Win 95 stuff on this forum since is not pertinent and
yes I realize that were asking for programming how to
info.

	Cheers,
