DiskDupe Locks up the Computer

(Pro/Auto/AutoPro)

If DiskDupe locks up the computer there is probably a conflict with a TSR (software) or with one of the adapter cards in the computer (hardware) 

Check for software conflicts:

First try booting off of a floppy disk so that the AUTOEXEC.BAT and CONFIG.SYS are "clean". 

If DiskDupe does not lock up under these conditions then you need to eliminate the source of the trouble by "remarking" lines in the CONFIG.SYS and AUTOEXEC.BAT one at a time. 

If the lock up problem persists after a clean boot there is probably a conflict with one of the cards in the computer. If this is the case then the conflicting card can be identified by removing the cards one at a time and trying the software. Once a card is isolated as the source of the conflict then the card can be jumpered to use another address, interrupt, or DMA channel to prevent the conflict.

To find the conflicting card: 

Start by removing the network card (if there is one). If the program still locks then try removing other cards one at a time, rebooting and testing DiskDupe to see if it locks. Try DiskDupe with just the Primary controller. If that fixes the problem then move the floppy card or the network card to another address and reenter the controllers.

When conflicting card has been isolated:

ADDRESSES: When DiskDupe starts it writes to the floppy controller addresses. The main floppy controller addresses are 3F0(Primary), 370(Secondary), and 360. If the conflicting card is using one of these addresses it will have to be moved to another address.

INTERRUPTS: Interrupt 6 is reserved for the floppy controllers and should not be used by other cards.

DMA CHANNELS: DMA 2 is reserved for the floppy controller and should not be used by other cards. Several times we have seen a lockup problem when a network card was jumpered to use one of the addresses for the secondary controller. This setting the "Secondary Controller" to "None" in DiskDupe. If this fixes the problem then the network card will need. To reassure yourself that the DiskDupe software is not corrupted you can check it on another computer.
