Support for the 4/600 officially ended at Solaris 2.5.1.  You can run 2.6
or 7 (and even Solaris 8 beta), but there are some limitations:

  The SM100 modules will not work.  It's SuperSparc/HyperSparc only.
  The VME bus will not work.  It's sbus only for expansion.
  It's totally and completely unsupported.

Use adb to comment out the halt after the call to iam_ss600 in the kernel
startup routine.  More details are available in the list archives or via
Dejanews.
