HARDWARE CONFLICT TESTS - JUMBO & TRAKKER
                            rev 9/93

If you have tried a clean boot and are still having hardware
conflicts, try the following tests:

1.   Use the turbo button, or look up the keyboard turbo function
     for your computer in the manual to take your system out of
     turbo mode.  If this resolves the problem, then your system
     bus is probably running too fast for your computer to do dual
     DMA (direct memory access) during tape backup operations, or
     the bus speed is just too fast for some of the cards in your
     system.  Slowing bus speed by using the turbo switch will also
     slow down your processor speed.  If your tape operation
     operates properly with the system slowed down, this indicates
     that you are a good candidate for fixing the problem by
     resetting the bus to a slower speed in the CMOS setups.  (You
     can access your CMOS setups on system start up or some
     companies provide setup diskettes with their computers.)

2.   Try Non-Concurrent Disk/Tape Operation.  Non-concurrent
     operation means that instead of trying to do a difficult dual
     DMA operation, the Colorado software will use a much easier
     single DMA transfer method.  Difficulty with dual DMA
     operations can be related to either the system board
     (Motherboard) of the floppy controller card.  Replacing the
     floppy controller, or using a dedicated Tape Controller Card
     (Colorado Memory Systems model FC-10) are alternatives if the
     current floppy controller is causing the problem.

3.   Certain 486 computers have processor caches that can interfere
     with tape performance.  Software versions starting with 3.XX
     will allow you to disable the processor cache on 486 systems
     while the tape software is running.  To disable caching on 486
     systems, use the following command line operation while you
     are in the tape sub directory (i.e. at the C:\TAPE prompt).
