This won't work because the TINYROOT floppy does not have a kernel in
/minix/ to make it possible to scram TINYROOT in 200k.  (The kernel is
sitting outside the file system in the leftover 160k.)

The TINYUSR2 floppy does have some extra space, so I put a kernel image
in the tmp/ directory.

Now, boot from TINYROOT, hit ESC, type

	rootdev=hd2a		(Assuming it is hd2a)
	boot

Login as root, replace TINYROOT by TINYUSR2 and type:

	M fd0				(Same as mount /dev/fd0 /fd0)
	cpdir /fd0 /usr			(Copy entire USR2 to /usr)
	cp -p /usr/tmp/* /minix		(Copy kernel image to its place)
	U fd0

And reboot.  Setup should have put a 'rootdev=hd2a' in the parameters of
you hard disk root file system so that hd2a is your root device instead
of the RAM disk.  You can now change /etc/hostname.file permanently.

You can hit F3 to turn on software scrolling.  Slow, but it works for
sure.
