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.
