Thanks, Tristram.  I often wonder what certain bits of a system are for, and
it is good to get this explanation.

Display chaining is what most screen readers currently do in order to pick
up information from the video subsystem of a Windows NT/2000/XP or VISTA PC
(until something better is working).  Display chaining consists of
installing and hooking into an existing working display chain and display
driver on the host PC.  Among the vast majority of vendors this now done
using a system called DCM (display chaining manager) to allow multiple AT
software to co-exist peacefully on a machine.  It is hoped (I would think by
all AT vendors) that a better alternative to this invasive information
gathering process will become available, during the VISTA product cycle.
Jaws 7.10 and 8.0 will run and speak without an installed and chained video
driver of its own, but functionality is a little limited but is often good
enough to get into a control panel and more obviously to allow a user to
re-install the video interceptor.

  What is Display Chaining Manager?  This comes up under the JAWS program
  submenu in startup menu.  When opening it it talks about video intercept,
  and something is installed but disabled.  Can someone in the know explain?
