All,
is it possible to detect whether a device is running at 66MHz (as opposed
to 33)? PCI defines a 66MHz capable bit, but not a 66MHz enabled bit. We
have a silly device that seems to need to know what it's bus speed is, but
have no way to tell from software (that I know of).
So, pray tell -- is there a way to figure it out?

There is, but unfortunately it's host bridge specific.
Have a nice fortnight

If a train station is where the train stops, what is a work station?
