Preparing the Computer for SM56 Installation

To ensure problem-free installation of the SM56 modem, ensure that an IRQ is available, as
follows.
1. In Win95/98, open the Control Panel.
2. Double click the System icon.
3. Select the Device Manager tab.
4. Highlight the Computer icon.
5. Select the Properties radio button.
6. Ensure that the Interrupt Request (IRQ) radio button is selected.
This displays the IRQ lines that are in use on the computer. Available lines are not shown in the
list. To install the SM56 ISA modem hardware, interrupt line 3, 4, 5, 6, 7, or 9 must be available.
The PCI SM56 software modem can use an IRQ in the range 3 through 15.
If there is no IRQ line available for the SM56 disable one of the COM ports in the BIOS.
Note: If you are using a Windows 95/98 DOS box application, the modem requires two IRQs.
Refer to the Troubleshooting section in this document, or to the on-line User's Guide for more
information on DOS application support. You can access the User's Guide through the modem
Control Panel.
Important: The SM56 PCI modem does not directly support DOS box applications. Please refer to
the Troubleshooting section for information on how to get around this limitation.
To ensure that COM Port 2, 3, or 4 is available, you can use the following steps:
1. Open the Control Panel.
2. Double click the System icon.
3. Choose the Device Manager tab.
4. Highlight the Ports (COM and LPT) branch.
