Justin T. Gibbs d0993d7584 Fix probes when a port address is specified. 
Convert from BT'isms to AHA'isms

Don't fail the probe if the illegal command bit is set in the status
register.  If the BusLogic MultiMaster probe preceeded us, it may well
have determined that the card we are attaching to was not a true MultiMaster
by sending us a command that fails on the 154X.

Reset the adapter before doing the inquiry.  This provides extra sanity
and will also clear the illegal command status bit that my be left over
from the MultiMaster probe.
