                     BRAVO LC/ADVANTAGE! VL-BUS SCSI CONTROLLERS

    PROBLEM:       Two VL-bus SCSI controllers experience problems when installed
                   in the Bravo LC/Advantage! systems which support VL-bus
                   adapters.

                   1) The Forex model FR600AF does not allow hard drive
                      partitions to be formatted under Windows NT.

                   2) The BusLogic model BT-445S does not function at all when
                      installed in the Bravo LC/Advantage! systems which support
                      VL-bus adapters.

    CAUSE:         1) At this writing, Forex does not know the cause of this
                      problem.

                   2) The BT-445S does not support the power management modes of
                      the Bravo LC.

    SYSTEMS
    AFFECTED:      Bravo LC with system board part number 202594-XXX.

    SOLUTION:      1) At this time there is no solution from Forex.

                   2) The solution is to replace model BT-445S with model BT445C.
