I can't really use scsitools bacause the drive has an unusual block size.
The kernel gives the following message durng bootup:

----

and I can't reach the second disk with scsitools (there's no sdb device).
I was told that a low level scsi format with the controller' disk utilities can modify the block
size.

so the question remains: how could I start the controller's utilities
before bootup?
