Hi all.

I am trying to write a fast data acquisition program using DJGPP and
Allegro. My problem is that I didn't do any PCI DMA transfer yet (or
any other DMA programming).  So I would be glad if anyone could point
me to relevant information.

Some more general questions are:

 Is it possible outside DOS memory?

 How much memory is accessible?

 Is there a good example program?
 (I have the sources of the Bolrland C driver of the card.)

 What are the problems a beginner does not consider?
