Controller Setup

(Pro/Auto/AutoPro)

This is where the floppy disk controllers are defined when editing or adding a controller to the Controller List.

• Name: Can be up to 20 characters.

• Type: This is the of the controller card that you are using. Almost all primary controllers are of the Standard type. Add-on controllers (also called "Secondary controllers") usually have the controller type labeled on the board itself.

• Base Address: This should be set up the same as the address jumper setting on your controller card. 3F0 is the Primary address (for A: and B:). Additional controller cards are jumpered to operate at other addresses. DiskDupe will allow you to list more than one controller at a given address even though it is impossible to operate two controllers at the same address. If your controller is at an address that is not listed, you can enter it in as a custom address and type in the address field below the Base Address field. See also CompatiCard IV.

• Interrupts: Most floppy controllers use Interrupt 6. The one exception to this rule is when two controllers are used to control an SDS drive. In this case the first controller (for head 0 of the drive) uses Interrupt 6 and the second controller uses no interrupt at all (Interrupt 0).

• DMA Channel: This needs to be set the same as the DMA Jumper settings on your controller card. If you are using an Allegro I, Allegro Mini or CompatiCard IV controller, you can leave this set to Auto and let DiskDupe determine the DMA channel. If you are using an Allegro II you must select a channel.

• DMA Burst Mode: The DMA burst mode needs to be turned on in order to operate high density double speed floppy drives. If you are using an CompatiCard IV or Allegro controller, you can leave this set to Auto.
