If you don't have a line in fstab, this should do:
Code:
mount -t vfat /dev/fd0 /media/floppy
given that the floppy is formatted with FAT filesystem and that /media/floppy directory exists. If you have a working fstab line, this should do:
Code:
mount /media/floppy
given that the mountpoint is defined to be /media/floppy.
What kind of error do you get?
EDIT: an fstab line could be something like this, for example:
Code:
/dev/fd0 /media/floppy vfat defaults 0 0
