Even the specs don't require this most PnP BIOSes seem to activate
everything that moves. For this reason it's often possible to get
soundcards (other cards as well) to work without using isapnptools.

The trick is very simple. If a logical device, I/O port, IRQ or so on is
not listed on card's PnP resource data, BIOS doesn't know anything about
this functionality and leaves it uninitialized. In case of EMU8000 only
the first of cards three I/O ports is listed on the resource data. In this
case PnP BIOS initializes this logical device and it's first I/O port.
However the device is not functional when initialized in this way.
