Rudy,
If all of the functionality is inside one chip, I would strongly
recommend to use only one PCI config header.
Our experience shows that using two functions that both identify
themselves as display devices in their class codes cause huge problems
unter Win95. You'll get resource conflicts (that are not physically real,
but Win95 creates them for you) and installation of drivers will be
troublesome (exactly the opposite of PnP).
The least you should do is to give the second functions unit any
reasonable class code other than display.
But, why don't you simple add the second function's resources (BARs) to
the first (VGA)?
