(OT HDW question update) update

[Stephen]

Id say try the adapter you have on the card you prefer. if it doesn't work
go to plan b.

Because i do know they can do odd things with the pinouts from a card and
allot of graphics vendors make VGA something that can be at least connected
and used. so while it is supposed to be A, you can get B and C to work too.
