SYMPTOMS
After you install Microsoft Windows 95, Microsoft Windows 98, Microsoft Windows 98 Second Edition or Microsoft Windows Millennium Edition (Me), on a laptop computer that has a Standard Microsystems (SMC) infrared communications controller (IrCC), you may receive the following error message:

Your network adapter SMC IrCC (Infrared Communications Controller - 0003) is not working properly. You may need to setup again. For information see the Network Troubleshooter in Windows Help.

Or, the IrCC may work on your laptop computer, but after IrCC resumes from the Hibernate or Standby mode it may not work and a code 33 or code 10 is displayed on the infrared port in Device Manager.



CAUSE
This behavior can occur if the basic input/output system (BIOS) assigns the same shared interrupt request (IRQ) to the SMC IrCC as well as to another device. The SMC IrCC requires its own IRQ to work properly.



WORKAROUND
To work around this behavior, manually assign a different IRQ to the device that currently shares the same IRQ as the SMC IrCC. To do this, use the following steps:
 * 1) Click Start, click Settings, and then click Control Panel.
 * 2) Double-click System, and then click the Device Manager tab.
 * 3) Click the plus sign (+) that is to the left of the SMC IrCC port, and then double-click the SMC IrCC device.
 * 4) Click the Resources tab, and then in the Resource type column, find Interrupt Request, record the number in the Settings column beside Interrupt Request, and then click Close.

NOTE: the IRQ is usually four, however, it could be different. If it is different, it may be necessary to open all the devices in Device Manager to find the device that has the IRQ conflict.
 * 1) If the SMC IrCC device is using IRQ number four, click the plus sign (+) that is to the left of Ports (COM and LPT) in Device Manager, and then double-click Com 1.
 * 2) Click the Resources tab, and then in the Resource type column, find Interrupt Request, record the number in the Settings column beside Interrupt Request. If the number is four, manually change the IRQ to three.
 * 3) To manually change the IRQ, click to clear the Use automatic settings check box, and then in the Settings based on box, click Basic Configuration 0001.

NOTE: Look at the Conflicting device list at the bottom of this tab. If there is a device listed, click a different Basic configuration setting until the conflict is resolved.
 * 1) Click OK, click OK, and when you are prompted to restart the computer, click Yes.
