I've been googling around trying to figure out if UIO is the same
thing as PCI-E. Supermicro has a bunch of motherboards for which the
description explicitly points out PCI-E and UIO slots, which makes it
sounds like they're different beasts.
Or, it could be that a UIO slot is specifically a PCI-Ex8 slot? You
can buy risers that convert "1U PCI-E (x16) to 1 UIO and 1 PCI-E "
Supermicro's description of the card does explicitly say that it "uses
a PCI Express host interface", but maybe they mean that they're using
it in some nonstandard fashion?
It's confusing...
