  3. KNOWN LIMITATIONS

     For certain motherboard chipsets, Windows 95, 98 and Me will
     fail to assign the ClassicBoard PCI an IRQ.  Consequently,
     the card's ports will be inaccessible.

     If Windows fails to open any ClassicBoard PCI port after what
     appears to be a successful installation, first check that
     the ClassicBoard PCI is assigned an IRQ:

     1. From the Start menu, choose Settings > Control Panel > 
        System > Device Manager.  View devices by type should 
        already have been selected by default.
     2. Expand the Multi-port Serial Cards category (click on 
        the plus-in-the-box to expand the list of serial cards).
     3. Highlight the ClassicBoard PCI card and choose Properties.
     4. Select the Resources tab.
     5. Under Resource settings should be an Interrupt Request
        Resource type.  If you don't see an Interrupt Request
        listed, you may need to upgrade the PCI IRQ Routing 
        Miniport Driver.

     If the ClassicBoard PCI is not assigned an IRQ, next 
     examine the PCI bus properties:
     
     1. From the Start menu, choose Settings > Control Panel > 
        System > Device Manager.
     2. Expand the System devices category.
     3. Highlight the PCI bus device and choose Properties.
     4. Select the IRQ Steering tab.
     5. Use IRQ Steering should be checked.  If not, enable 
        IRQ steering and reboot Windows before continuing.
     6. Lastly, look at the IRQ Routing Status information.  
        If the device is functioning properly, Windows will 
        report both IRQ Steering Enabled and IRQ Miniport 
        Loaded successfully.  Otherwise, Windows will report 
        IRQ Steering Disabled and Miniport rejected IRQ Table.
     
     If Windows reports IRQ Steering Disabled, you need to 
     upgrade the PCI IRQ Routing Miniport driver.  This driver
     can be downloaded from the chipset manufacturer's Web site.  
     To identify which chipset your motherboard uses, refer to 
     the hardware documentation that accompanied your computer.

     Following are links to the Web sites of chipset manufacturers 
     for which this problem has been identified.  Note that this 
     list is incomplete and that we cannot guarantee that the 
     provided Web site addresses are valid.  Download and install
     the miniport driver at your own risk.
