What are you booting from? If you have an Ultra-60, you likely have
processors faster than 419MHz. If so, you can't boot from a Solaris
2.5.1 or 2.6 CDrom. You must boot Solaris 7, or the Operating
Environment CD that comes with the machine.

Special thanks to Scott Darren and Miller Sutfin. Both have
hit the head of the nail. The problem is due to fault memory.
