That would be correct. PnPBIOS is obsoleted by ACPI so a 64bit x86
platform shouldn't be using PnPBIOS nor anything non x86. Strictly
speaking PnpBIOS is not ISA, it's onboard devices.

ISA devices that can be enumerated are usually enumerated via ISAPnP
which is platform independent.

Quite a few of the ISA drivers if you review them more carefully have
other endian and size assumptions, IRQ assumptions and probably fun bugs
because they've simply never been run on anything else even when it is
possible.
