I can reproduce all the above error messages if I invoke the sun4 version
of eeprom (i.e. /export/exec/kvm/sun4.sunos.4.1/eeprom) on my SS1+.

The sun4c version of eeprom worked fine for us all along.  We got a few
dozen SS1/SS1+'s with ROM revisions 1.2/1.3 all running SunOS 4.1.  BTW,
the checksum for the sun4c version of eeprom is 25073 while the sun4
version of eeprom, 09014.
