ProDOS currently allows a total of six drive devices to function at one time. The Smart Fort, where your ROM Disk resides, can control up to four of the 6 total drives.

You can have four 3.5” drives daisy-chained to the Smart Port or you can have a ROM Disk, a RAM Disk, and two

3.5drives. The Smart Port drives are controlled separately from drives connected to a disk drive controller in slot 6 and separately from a hard disk in 7.

The Smart Port will access the drives in the order:

Slot 5 Drive 1 (boot drive - set up in Control Panel) Slot 5 Drive 2

Slot 2 Drive 1

Slot 2 Drive 2.

While there are no drives actually connected to slot 2, this is the slot that the Smart Port allocates to the 3rd and 4th drives in the Smart Port drive chain. These are the only slots that will be used by the Smart Port to control disk drives. For additional information about the Smart Port, consult your Apple IIGS User’s Guide.

Slot 2 Consideration

Slot 2 is commonly used for modems. Since the modem doesn’t emulate a block device (disk drive), if you have a modem in slot 2 (a DataLink for example) and slot 2 is set to “Your Card” in the Control Panel, the Smart Port can still use Slot 2 for disk drive allocation. If a memory card that emulates a disk drive is in slot 2 (e.g. RamFactor), then that card will override the Smart Port’s 3rd and 4th drives.
