I have tried those settings now, with no success. If I play with the
Stereo Display Mode (switching to one of several choices further down
the list) I find that Chimera will recognize *something* and start
"sequential stereo," but it is totally useless and does not work
properly (it appears to create a low Hz rock in the image--presumably
the L/R images but I'm uncertain).
With the fiddling, it requires two sequential shutdowns (not reboots) of
the system to get the card to reset properly so that it works again
under Linux. I do not know if this is an issue with the Windows driver,
the OS itself and how it integrates with the driver, the card, the rest
of the HW involved, or what. I cannot get it to work, and my time needs
to go elsewhere.
I think I will forward this to the kind folks who helped us put the
system together (they sold us the Windows disks as well), and see if
they would be willing to switch out one of the unused disks for Win 7
Pro, just to see if it makes a difference. If so...
Thanks very much for your input!

In a completely rational society, the best of us would aspire to be
_teachers_ and the rest of us would have to settle for something less,
because passing civilization along from one generation to the next
ought to be the highest honor and the highest responsibility anyone
could have. - Lee Iacocca
