I doubt seriously this is the case. Otherwise our isa bridge code would attach another isa bus there and he'd not have a problem. : I remember that there were 1-ISA-device-PCI-ISA bridges when PCI : first came out; this is probably one of them. actually, there were and are a lot of localbus (aka ISA) to PCI bridges out there. These are PCI devices, and should be treated as such. It is extremely rare for a full-fledged PCI to ISA bridge to be on an add-in card that isn't a specialized hunk of hardware. Something as common as a sound card almost certainly doesn't do this. That makes the rest of your questions irrelevant.... Warner
