               ASCENTIA 900N PARALLEL PORT AND THIRD PARTY HARDWARE/SOFTWARE

    PROBLEM:        When some third party devices are connected to the Ascentia
                    900N parallel port, the software does not properly recognize
                    the interrupt on LPT1.  For example, the following error
                    message may appear on the display:

                         "IRQ 7 could not be found on LPT1"

    CAUSE:          Older versions of software do not properly recognize the VLSI
                    implementation of the super I/O chipset.

                    implementation.
