I just read the auction description and, with my Fastlane Z3 at least, you don't need to load a special driver for SCSI. The driver is automacally loaded from the Fastlanes ROM and any SCSI drives connected to it will be recognized by the Amiga. I think the floppy just has SCSI drive prep software and SCSI utilities on it. You do need to modify the .info file for HDToolbox and change scsi.device to z3scsi.device for it to work with the Fastlane.
