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.

By default, the installation utilities are located in the second tape file
on the NetBSD/sparc installation tape. In case your tape layout is different,
choose the appropriate tape file number below.
If the installation tape was written with a different block size than
the default suggested by this installation procedure, you have the
opportunity to change that as well.

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.
