I have been thinking about using a loader environment variable for this. One existing problem is that a pci device which doesn't match a driver does not reserve its irq resource. Fixing that still leaves the case of an unknown non-pnp isa device though. -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
