RE: [TOOLS] PCI-e versus PCI-e Graphic slots

["McLauchlan, Kevin" <Kevin -dot- McLauchlan -at- safenet-inc -dot- com>]

Whoops!  Apologies to Lech. His response was quarantined at my end. So
somebody DID respond.

As for that link, it's a little old and doesn't mention my minor
concern:
PCI-e x16 connectors are often/usually additionally qualified as
"graphics" or "gen2 graphics" connectors. 
So, my question was whether there was something special about the
connectors that have that qualifier in the blurb, or whether it's just a
way to say - "we made sure that there was at least one PCI-e x16 slot so
you'd have a place to put your video card"?

I've e-mailed requests to a couple of board vendors, but I have to
choose my future test platform today, or I won't likely get it in time
for the coming project. Maybe one of the vendors will reply today...
Is there an emoticon for "got my fingers crossed"?

Kevin
