              Bravo MS-T Windows 95 Auto-Adds Integrated COM Ports Causing
                             a Conflict with Internal Modem

    PROBLEM

    Windows 95 will auto-add the integrated COM ports even though the COM ports
    are DISABLED in CMOS Setup.  This addition will not allow the addition of an
    internal modem on COM1 or COM2.

    CAUSE

    Upon OS boot up using Windows 95, plug and play is detecting the machine
    hardware.

    SOLUTION

    Use Windows 95 Device Manager to DISABLE the integrated COM port.
    To do this, follow the steps below:

    1. Double-click the system icon from the control panel.
    2. Select the Device Manager.
    3. Double click on the COM port being used (COM1 or COM2).
    4. Uncheck the 'current configuration' box and choose 'OK'.  This should
       place a red 'X' on the associated COM port.
    5. Run the 'Add New Hardware' from control panel and allow it to
       auto-detect your hardware.  Windows95 will find the internal modem
       COM port.
    6. Run 'Add New Hardware' from control panel again.  Do not do an
       auto-detect.  Choose "modem."  Windows95 will test all available COM
       ports for a modem.

    SYSTEMS AFFECTED

    Any machine using a Plug and Play BIOS.
