>(actually applies to Microsparc 1 machines only).
There are only two microSPARC I CPU systems that Sun ever made: the
SPARC Classic, and the SPARC LX (well, and the "X terminal"
configurations of those two). Everything else since is microSPARC II,
including the Voyager, SS4, and SS5.
Can't this be shut off at boot after the CPU type is detected (or
turned on for all CPUs except the microSPARC I)?
