Matt,

Now I've tried working out what format SuSE uses for its
"modules" disk, and the result is - more woe!
(Nothing I ever try with linux ever seems to work without
a week's hard work and a lot of hacking. Maybe I'm just unlucky.
Or maybe I shouldn't buy so many computers.)

I had no idea what file system was used on the "modules" disk.
So I tried the obvious sorts of things:

=====================================================
emu /etc# mount /floppy
mount: wrong fs type, bad option, bad superblock on /dev/fd0,
       or too many mounted file systems  

emu /etc# mount -t msdos /dev/fd0 /floppy
mount: wrong fs type, bad option, bad superblock on /dev/fd0,
       or too many mounted file systems 

emu /etc# mount -t ext2 /dev/fd0 /floppy
mount: wrong fs type, bad option, bad superblock on /dev/fd0,
       or too many mounted file systems
emu /etc# mount -t minix /dev/fd0 /floppy
mount: wrong fs type, bad option, bad superblock on /dev/fd0,
       or too many mounted file systems
emu /etc# df
Filesystem         1024-blocks  Used Available Capacity Mounted on
/dev/hda2            11980143 11213700   393040     97%   /
/dev/hda1               9411    1914     6995     21%   /boot
/dev/hdb1              23300      13    22084      0%   /boot1
/dev/hdb2            28639083 13664726  13473886     50%   /home1
/dev/sda1            1024555  576878   394740     59%   /scsi1
fox.topology.org:/home2
                     12236587 10742257   858585     93%   /home2
emu /etc# mount -t vfat /dev/fd0 /floppy
Segmentation fault
emu /etc# mount -t msdos /dev/fd0 /floppy
                                         
====================================================

And now the process trying to mount that floppy disk is totally hung.


I can't believe that the file system is not one of those I tried.
Is there any better way to determine a file system type than
trial and error?

I've done a "dd" on the floppy disk, but I have no idea which
bytes I should look at to determine the file system type.
