        Assuming your system has a PnP BIOS you should be ok, as long as the 
PnP BIOS knows about all the non-PnP hardware in your system.   If the PnP 
BIOS has not be told what resources are used by your ISA I/O card then 
it will assign the I/O addresses and IRQs used by that ISA card to 
the PnP cards it finds.

        In a PnP BIOS there is an option to allocate resources to ISA cards, 
for example on IRQs you typically get a menu which lists all the IRQs and 
lets you assign them to ISA (ie. non-PnP cards), PnP or PCI.   Sometimes the 
ISA setting is referred to as "disabled" or "unavailable".  (This depends on 
the PnP BIOS, since I haven't used an Award PnP BIOS I don't know how they 
describe this option.)

         Once the PnP BIOS knows what resources (IRQs, DMA channels, I/O 
addresses) are used by non-PnP hardware it can then correctly assign resources 
to the PnP devices without any conflicts.
