SPARC: How to Boot a System Interactively

1. Boot the system interactively by using the boot -a command.

   ok boot -a

2. Answer the system prompts as described in Table 8-2.

   Enter filename [kernel/unix]:	Provide the name of another kernel to use for booting.  Or, press Return to use the default kernel (/platform/`uname -m`/kernel/unix).
