I have ONLY the z-3i SCSI device!!!
I tried also with others (but with a z-2i busboard) and the Blizzard does not work with ANY SCSI cards!!! I do not know it this is a problem of my card or if there is something I can do (jumper, setting, something else...).
It does not even work with my Blizzard SCSI kit in a standar A1200!!! 
There is your problem!
You need to have 1230scsi.device because that is the driver.
With your Blizzard cards, you should have received the disks which contain all the software you need to enable the cards to work
You need 1230scsi.device installed.
