UNIX for Dummies Questions & Answers

Hi,
i want to mount a floppy disk device on a System V/68 Release R3V6 system because i want to copy some files from this Unix computer to a Win-98 based computer.

I have logged in as "root" and used command line:
mount /dev/f0ps2 /floppy (the "floppy folder" on the computer i'm working on is "/dev/f0ps2" not /dev/fd0)

When no floppy disk is in, it displays the following error message:
"Physical Block! 0X0(0)Command Byte:70Status Byte1:22
mount: I/O error
mount: cannot mount /dev/f0ps2"

When i insert a FAT formatted floppy disk, it says:
"mount: /dev/f0ps2 not a valid file system"

I've tried command line:
"mount -f DOS /dev/f0ps2 /floppy" but it doesn't work.
It seems that DOS filesystem is not installed.
I've seen on a site that available filesystems can be found at /etc/filesys.
(no filesys file in /etc/default folder (no /etc/default folder))
I've opened it ("vi /etc/filesys") and heres what i got:

Slice Alias fsize perms mnt_pt 'format_pgn'
m320_2s0 floppy 1264 RWMF /flp '/etc/dinit -b /stan
d/m68k/boots/vmeboot -f m320dsddS'
m320_2s0 pcflp 2370 RWMF /flp '/etc/dinit -b /stan
d/m68k/boots/vmeboot -f m320dsddS'

Do i need to format floppy disk with another file system?
What are the avaible filesystems?

i've tried some mount commands and the only filesystem available seems to be "S51K" filesystem.
