To check which controler PB550c use, I investigated the Gesutalt value
of Hardware attributes, it said that PB550c uses the 5380 chip!!!
I tried to boot with 'ncrscsi0' driver again, the booting process stopped
after the message "Changing root device to sd0a." was displayed....
I don't know why the 'sbc0' driver works on PB550c.

O.K. I tried doing it. Following is the result.
