Nope,only 3 more allowed, the controller itself is one bus address in the 
scsi scheme of things.  scsi bus device addresses are a single set bit, 
walking across the byte-wide bus. The controller itself is normally at 
$80.  Drive 0 is actually $01, drive 1 is $02, next is $04, $08, $10, $20, 
$40.
