[rescue] Sun 3 with SCSI2SD

[Mike Spooner]

IIRC, the "ready response" that OBP waits for is the response packet to theB 
IDENTIFY ("what's your make and model"?) SCSI command..

not sure how this relates, but hds have a jumper i always set, to spin
up on first access instead of poweron; my thinking was that the load
on the ps was never higher than at poweron and this would reduce the
surge by a meaningful fraction while adding only seconds to cold boot.

could there be a 'ready' signal/message the disk returns to the obp?
