connectin pc and ESI4000 to jaz drive

i have a jaz drive connected to my pc and i would like to chain my esi4000 to it. i bought mine used, but i heard rumors of software that comes with it for setting up SCSI. right now windows has no drivers, and i dont know how to get the 4000 to terminate the SCSI chain. im hoping to eventually be able to send samples thru the SCSI from soundforge. if u have, or know where to find software for the 4000, please help!

thanks!
