First, remove the boot disk from the floppy station.

Next, insert the floppy disk labeled \`instfs' into the disk drive.
The question below allows you to specify the device name of the floppy
drive.  Usually, the default device will do just fine.

Welcome to the NetBSD/sparc microroot setup utility.

We've just completed the first stage of a two-stage procedure to load a

second stage which is to follow now, a set of additional installation
utilities must be load from your NetBSD/sparc installation medium.
