   SmartPort Query   
   23 Aug 23 01:40:28   
   
   From: gids.rs@sasktel.net   
      
   I have come to the conclusion that Smartport in Slot #7 queries each slot for   
   a device in this order:   
      
   Slot 7 Drv 1   
   Slot 7 Drv 2   
   Slot 4 Drv 1   
   Slot 4 Drv 2   
   Slot 1 Drv 1   
   Slot 1 Drv 2   
   Slot 2 Drv 1   
   Slot 2 Drv 2   
   Slot 3 Drv 1   
   Slot 6 Drv 1   
   Slot 6 Drv 2   
   Slot 3 Drv 2   
      
   for a total of 12 devices.  In IIGS emulators, a hard drive disk image is   
   automatically mounted to the next available Slot/Drive.  If I have a boot disk   
   in Slot 7 Drv 1, then mount another hard drive, it automatically is inserted   
   as Slot 7 Drv 2 for    
   device #2.  And the next hard drive is seen as Slot 4 Drv 1, which makes this   
   device #3.   
      
   But on a real IIGS, there may not be a Slot 7 Drv 2 if the volume in Drv 1 is   
   less than 65536 blocks as I believe it is the firmware that sees drive #2.   
      
   Therefore, I believe inserting another hard drive in Slot #4 via SCSI/CFFA/SD   
   should be seen as device #2 instead of device #3.   
      
   If that is the case, then the Smartport in the firmware of Slot #7 would need   
   to keep a translation table somewhere in memory to know that Device #2 is in   
   Slot 4 Drv 1 and not Slot 7 Drv 2.   
      
   Is this the correct assumption, or is it just as simple as the device number   
   being in the order that I laid out above?  I am asking what is the arrangement   
   on a real IIGS, and not emulators, as I only have one CFFA card to test this   
   scenario.
