What's the difference between "built in" and "on the PCI bus"? Both
types are physically a part of the mainboard, and need to be quirked, right?
The corner case I was referring to is where someone plugs an *external*
VIA-based PCI card into a PCI slot on a VIA motherboard. In that case,
the PCI card gets quirked too, when it didn't need to be, and this may
or may not cause problems...
You know from the northbridge which devices are internal and which are
external.
I don't know much about PCI. How can I detect this?
Alternatively if you (or anyone else who knows PCI) wants to write a new
patch or modify the existing one I would have no objections. I can also
get a few people to test it.
Thanks.
