  I may have confused you: use fdimage.exe on WindowsNT4/5/5.1
(rawrite.exe on DOSy windows like 95/98); you can find them on
FreeBSD ftp servers in pub/FreeBSD/tools directory, e.g.

ftp://ftp.freebsd.org/pub/FreeBSD/tools

where you can also find other wonderful UNIX tools ported to Win like
md5.exe (there is also a bunch of unitilities for win on etree
servers, they have md5sum.exe there) Speaking of Free or semi-free
software most folks forget that there is a huge volume of excellent
freeware progs for the Evil OS.

On UNIXy systems you need to learn dd command/utility/programme

where 2 main arguments could be mnemonised as 'output file' and
'input file' - of and if respectively. UNIX tries to treat nearly
everything as a file (actually it's scion, Plan9 treats everything
so, even CPUs are files, so you can write and read to/from them). So
with dd you make *raw transfer* from output to input without logical
processing of any sort (like error checking, structural
verifications). I always keep for emergencies an image of a bootable
DOSy floppy with either some additional utils or bare. Additionals
can be fdisk, I/O libraries (e.g. CD support), etc. Metaphorically
you can treat DOS like UNIX without real multitasking and
multieverythingelse with different syntax.

So, when you copy a boot floppy on a linux machine (for example), you
create an image of it in your home directory like this:

  dd if=/dev/fd0 of=boo.floppy  (you can name it anyway, e.g.   
dos_fdisk.flp, sheercrap.img, etc)

I took linux as an example, because in modern boxes Macs dropped
floppies some time ago, and I have no experience with X, but I have
quite a bit of experience with Solaris, IRIX and FreeBSD mostly, and
there shouldn't be huge difference within the NIXy environment for
this command. Some flavours, depending on the installation profile
may need more options with dd line, so read the manuals for dd and
fdformat, read several times before going to Internet and typing "dd
tutorial", "how to format diskette[s] in
UNIX/Linux/FreeBSD/Whatevernix" and then if you still don't get it
ask on Usenet or some other dedicated hangout. Keep in mind that the
crowd there may be different, you have been spoiled by macsters who
have the best sense of humour, those other folks may be intolerable
at times, especially neophytes posing as geeks.
I think that freebsd crowd is most helpful and professional. And
their online Handbook is truly excellent.

Keep in mind that UNIX is rather old and even though it progressed
hugely over time, taking it is a base for Mac OS is no way innovation
in my book. But it can be a lot of fun. Still, "for the rest of us"
in me :) it's not the way to go IMHO. I better stop right here :)
