Filesystems on floppies

[roberto at tuintje.cwi.nl]

Hi there!

A question: I have a SparcStation 1 with a floppy drive. I want to use
floppies as small file systems. In the STB of last July there were some
hints on how to do this:

mkfs /dev/rfd0c 2844 18 2

and now you should be able to mount it. I don't what I did wrong but this
doesn't work for me. When I try to mount it on, say, /diskette: 

mount /dev/fd0c /diskette 

I get the error message:

mount: /dev/fd0c on /diskette: No such device or address

I use a high density double sided floppy. Perhaps the parameters are
wrong, but how do I find this out? If someone knows what I should do to
make it work: let me know!!!

Thanx in advance.
