   Does anyone know which sun4m machines use the macio/slavio chipset
   and how to detect it?

All sun4m's are some variant of the NCR Sbus/IO subsystem glue logic,
only difference on 4/690's and ss10/20 is that the interrupt/timer
registers are in multiples of 4 for SMP.

vger.rutgers.edu:/pub/linux/Sparc/NCR

has most of the docs in textual format.  This is basically what SLAVIO
refers to.  Aaron has these docs available on his ftp site as well, he
got them from me.
