Press <code>b cdrom</code> and hit enter to boot into the CD.

When you partition the disk, make sure that: Partition A is the boot partition, partition B is swap, and partitions G and H contain the majority of the disk. Make sure Partition C spans the entirety of the disk. I have no idea why you need to set it up in this way, but this is how SunOS expects it to be set up.
DON'T FORMAT THE DISK unless you have several hours to kill. You only need to label the disk when its partitioned.
When you reboot into the miniroot type <code>suninstall</code> to start installing the OS.
