The unit still does not boot up. If the system bus configuration checks out, then the boot
path, or NVRAM may be suspect. Refer to the OpenBoot Command Reference Guide for
instructions on accessing and modifying the OpenBoot PROM.
Check boot path. If path is correct but will not boot, the problem could be in the
boot disk, SBus interface card, or cable.

If the boot path is OK, but still doesn't boot, attempt to boot off Ethernet.
To test the network, use the OBP command watch-net.
