What happened after the machine rebooted?

In a normal run of events, once you hit the apply button, then slave
node will get an IP, then imediately request a phase2 beoboot image from
the master and download that.  This can happen pretty quickly over a
fast network.  Once it has the phase2 beoboot image, it will do what we
call the 2-kernel monte.  It will boot the kernel that is on the phase2
floppy.  You will see the normal stuff for a kernel boot, however this
isn't quite a normal reboot as it never goes back to BIOS or anything
like that.  Once it has booted the kernel from the phase2 image, it will
RARP again, and once it has its IP it will start up sendstats and
bpslave, and once bpslave is up, the status of the slave node should
change in beosetup.
