Sorry to bother you all again, this will be my last mail about the subject.
I managed to overcome the checksum problem and have written a dirty little
program that will, based on a chunk of the firmware, ask for a new login and
password and then show how that chunk must be rewritten (you still have to
do this by hand). The program source is available on demand. The login is
reduced to 9 characters instead of the usual 14, and some of the missing
bytes are used to make an checksum correct image.
Thanks go to Russell Coker (bofh@coker.com.au), who's mail made me go back
and see what gross mistakes I had made on previous attempts.
Have a nice day.
