	| Setup is now done with the migration to disk, so it   |
	| wants me to type 'halt' and 'boot hd3'.  It says      |
	| "please", so I comply:                                |
	+-------------------------------------------------------+

Please insert the installation ROOT floppy and type 'halt' to exit Minix.
You can type 'boot hd3' to try the newly installed Minix system.  See
"TESTING" in the usage manual.
# halt

	| Usage(8) warns about this "File exists" message, and  |
	| that it doesn't matter.  Otherwise this would go      |

	+-------------------------------------------------------+
	| Lots of files installed, I add floppy 2 and 3 of      |
	| USR.TAZ when it asks for them.  When done I type      |
	| "setup /usr" again for SYS.TAZ, and once more for     |
	| CMD.TAZ.  Five floppies later and I'm done.           |

	| As an example I give the system the name "finiah",    |
	| but seeing one of Michael Temari's network programs   |
	| extracted inspires me to make a network kernel.  Log  |

	| true editor of the aging computer geek:               |

	| The new boot messages show that things have changed.  |
	| The ethernet driver has found an NE2000, the larger   |
	| block cache has made the kernel (MINIX) larger, and   |
	| the RAM disk is done away with.  One of my other PC's |
	| has seen fit to answer the RARP request (here is my   |
	| ethernet address, what is my IP address?) of my       |
	| notebook, but the notebook doesn't yet know how to    |
	| translate 127.36.93.27 to its own name yet.           |
