I recently did some converting from 5.25 to 3.5 inch diskettes by getting on a
machine with both types flopies and using one of two techniques (note: in my
examples, fd0 is 5.25", fd1 is 3.5"):

	cp /dev/fd0 /dev/fd1 
	^^ dd with a large blocking factor is faster

gives a 360K 40-track filesystem (or a boot diskette) on a 3.5" diskette
(not very efficent), or...

	mkfs /dev/at1 720
	/etc/mount /dev/at1 /user

gets out 720K diskette on /user (use cpdir or something from there).  3.5"
diskettes look just like a 5.25" to the controler; they've just got twice as
many tracks. 

You may need some hacks to make Minix work at all on the PS/2 (half a
computer); check the message archives (index minix-l) on ndsuvm1.bitnet or
bugs.nosc.mil for them
