[ "A car is just a big purse on wheels."   --Johanna Reynolds ]

Attached are a couple small files that are making the BBS rounds, on how
you can utilize the FFS on your *floppy* drives under 1.3.

I did check with "Mr. FFS" at CBM (Steve Beats) before posting this, who
replied:

Sooooo ... anyone out there with Gamma 7 (etc.) want to comment on just
how *Fassssssst* our floppys can be ...?

echo x - README
cat > "README" << '//E*O*F README//'
This mount list will let you use the Fast File System (FFS) on a Floppy
drive.  The only important part of this mountlist is the one labeled
"DF3:".

As it is right now the Floppy which will be formated with FFS will be
labeled as DF3: even though it will really be DF0:.  If you notice in
this mountlist label DF3: has a UNIT = 0 this points to df0: but if you
wanted to use the external drive (DF1:) you would have to change this
to UNIT = 1.  Which ever drive you decide to use this will be the only
drive that the disk formated with FFS will be able to be used in.  If
you insert it in the other drive you will get that NO DOS message.  

You can either replace your present MountList in the DEVS directory with
this MountList or you can just Edit yours and ADD the part labeled DF3:.
If you decide to edit yours don't forget the # sign at the bottom or it
will not work correctly.

Now after you have this MounList in your WorkBench 1.3 Devs directory you
will still have to mount it so that the Amiga can see it.  The easiest
way is to add a comand to you Startup-Sequence, something like:

                          Mount DF3:

Of course do this before the Endcli part of your Startup-Sequence (I know
everybody knows this but I had to say it just in case).

Then all you have to do is reboot with your Woorkbench 1.3 disk (The one
with the new mountlist) and open your CLI and Format a disk using the FFS
system.

For example if you were to leave it the way it is DF0: would be the FFS
drive so you would type:

            FORMAT DRIVE DF3: NAME MyDisk FFS <RETURN>

At this the Amiga will say to put in the disk to formated into DF3: which
in reallity is DF0: and to hit return.  When you do this and the Amiga
formats the Disk you will get 2 Icons for the same disk 1 will say NODOS
and the other will have the name of your disk, which in this example is
MyDisk .  You will ignore the NODOS Icon and just use other Icon.  If you
decide to change the UNIT to 1 then everything is the same except when the
Amiga tells you to insert the disk to be formated in DF3: you insert it in
DF1:.  (Simple enough)

This about covers everything I can think of except to say that remeber to
do this only on a Backup of your Workbench 1.3 disk and that I am just
passing along information and you are doing this at your own risk.  And I
take no responsibilities for any damage to software or hardware caused by
you trying this procedure.  If you are thinking after reading this diclaim
er "Wow Sarge is letting this go to his head." You are probably right, but
once I get started I get inspired and besides EVERYONE ELSE DOES IT so
there.
