It's a design flaw ... er, feature ... of all such cards. They all depend upon SCSI Manager 4.3 being able to dynamically add SCSI buses to any machine which is supported by SCSI Manager 4.3. EIDE/UATA buses cannot be dynamically added. So, the power-on restart code of the MacOS (7.6.1 and later, IIRC) scans all PCI slots for cards, and invokes the Open Firmware (OF) boot code for each card in succession. That boot code initializes the card. For EIDE/UATA cards, this means determining the drives which are attached, and adding them to the "mount queue". Then the OF code returns to the MacOS with the indication that it is a SCSI card which has drives attached. This is done for each EIDE/UATA card in succession. You can have a maximum of four such cards in a six-slot machine, and (obviously) a maximum of three such cards in a three-slot machine. The drives are later recognized in the "mount queue" and wind up on the desktop as SCSI drives. -- G-List is sponsored by <http://lowendmac.com/> and...
