Hello Bill, how are you to day?
Me i'm fine.
Thousand of thank's to you for your help.
I have solved the problem by the same way the last night.
My solution was to make a 'fdisk wd0' command to see where
was my DOS partition. 
The second command was 'disklabel -i wd0' and add a partition 'f'.
The partition begin at 6552 and the size is 65520.
The unit in use was effectivly in sectors.
Then, I mount my partition by 'mount -t msdos /dev/wd0f /mnt2.
At this point, I see my set directory on my MSDOS disk.
All is riht for now.
Than's you again.
Bye.
Richard from PARIS in FRANCE.
