This should be the next menu step after you’ve mounted your root
partition, unless you’ve already performed this step in a previous
run of dbootstrap. First, you will be asked to confirm that the
device you have mounted on root is the proper one. Next, you will be
offered a menu of devices from which you can install the kernel.
Choose the appropriate device from which to install the kernel and
modules; this will either be a CD-ROM device or the first floppy
device.
If you’re installing from floppies, you’ll need to feed in the
Rescue Floppy (which is probably already in the drive), followed by
the Drivers Floppy.
