He made a very smart work to select 'default' system configuration in
zs_ioasic_submatch() routine.  When zs devices are configured as
'default', the routine automagically generates different match
sequences, one for 3MIN/3MAX+ case, and another for MAXINE.  With
an explicit designation, it is followed as specified. 

3100 and 5100 can be treated in the same way.
