I'm sure that this has been answered before, but ...

  How do you cause a graphics screen dump from inside a 
program on an AT. For example, I want to simulate the effect
of a  which dumps Page 0 from my Herc card.
I imagine that you use BIOS INT 5H, but how do you tell the BIOS
which page to dump?
