the scsi controler of Cyberstorm must be bootable as is mine 1230 scsi controler. just install the softwear of the scsi controler and when you run hdtoolbox select the specific scsi.device. in my bliz1260 the scsi dev name is 1230scsi.device for example. all the procedure after the selection of scsi device is the same as with ide drives. here you will find the latest softwear from phase5 :
