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

[McLauchlan, Kevin]

Other than a really pretty line of carats "^^^^^^" from ASTeC, nobody
responded.   :-)

Does anybody know if there's anything special about PCI-e slots that are
designated "graphics" (or "gen2 graphics")?
Googling has not yet revealed if they have special additions or
restrictions to make them function differently than a "standard" PCI-e
x16 slot should.
