???

Oh, I see the mistake. Almost every SCSI device has at least 3 pairs of
jumpers. To set the ID it is something like this (I am using : for open
jumpers and I for closed jumpers):

::: - ID 0
I:: - ID 1
:I: - ID 2
II: - ID 3 (1+2)
::I - ID 4
I:I - ID 5 (1+4)
:II - ID 6 (2+4)
III - ID 7 (1+2+4)

See how that works?
