the netbsd disk is indeed ID1.

apropos SCSI id's and 'internal' numbers (sd0 etc).. Could the internal
bus have priority? I think if someone has internal disks they should
retain their ID and so always boot correctly.

I noticed this when I tried to test my externalboot disk I tried on the
9600 on the 9500: the boot disk get shifted because of the external
disk. This seems stupid to me. "external is external".

Also I noticed however that on the 9500 the kernel identifies the
external hard disk! on the 9600 not... strange..
