Cool!  Will you be adding an option whether to include PCI or not in the 
host?  I believe that only devices actually on the ISA bus (not those on 
the PCI bus) will participate in the ISAPNP process.  If PCI is enabled, 
the ISAPNP enumerator should not respond (since no ISA devices are 
around to participate in the process). 

I suppose it might not be very useful to add ISAPNP if something as old 
as Windows '95 supports PCI.  PCI is far better for device enumeration 
anyways.  Might be better to wait in this case.  :)

Matt.
