isapnp(4) - how does it work on non-PnP machines?

[Felix Deichmann <m4j0rd0m0%gmail.com@localhost>]

Hi,

I acquired some nice ISAPNP cards like wss(4) and le(4) recently which
I will test in the next days in a 486 system without PnP BIOS.
How does isapnp(4) work in this case, how does it allocate device
resources (i. e. know which resources are free)?
Can I also specify resources *not* to use somehow, like for devices
not supported by a driver?
