OK, and now the other way around. I have a 1.44 MB boot floppy
and want to produce a 1.2 MB boot floppy. I imagined this would work
on a system with a 1.2 MB boot drive and a secondary 1.44 MB drive:

	format /dev/rdsk/f0q15dt
	dd if=/etc/fboot of=/dev/dsk/f0q15dt
	mkfs /dev/dsk/f0q15d 2370:144 1 32
	labelit /dev/dsk/f0q15d instal flop
	mkdir /a /b
	mount /dev/dsk/f0q15d /a
	mount -r /dev/dsk/f1q18d /b
	cd /b
	find . -print | cpio -pdmuav /a

This boot diskette will boot, display copyright messages,
but then complains with:

	FD drv 0, blk 1581: Sector not found
	NOTICE: page read error on floppy disk 0, partition 2

So, what went wrong?
