Right, the output of pnpdump is exactly a isapnp.conf file with everything commented out. The key
thing though is that it puts in the necessary device lines so that you can address the device you
want to configure. The idea is that you first run pnpdump to create the template and then edit it
to create your isapnp.conf. Why don't you email me the output of pnpdump and we'll take a look.
