looking at what's on these cards I can see no way they're doing a full PCI compliant interface. So I assume they snoop but do nothing else. Some other evidence. If you plug in both ISA and PCI cards they will show the same values. If the PCI card were responding to FRAME# then I don't see the I/O being forwarded to ISA. ron
