PCLTA-21 PCI Interface User’s Guide

The PCLTA-21 LONWORKS Network Interface device icon is found under the

ONWORKS Interface device type. If there is a problem with the card, there

will be a red circle with an exclamation point next to its icon.

IRQ resource problems may generally be resolved by disabling another

device in the system. More information can be found in the Hardware

Conflict troubleshooting portion of the Windows 98 on-line Help file.

Access the hardware conflict troubleshooter through the procedure outlined

below:

1. Open the Windows 98 on-line help by clicking the Windows Start button and

selecting Help.

2. In the Help Topics window, choose the Contents tab, or from another Help

window, choose the Contents button.

3. Double-click the Troubleshooting topic, and then select the If You Have A

Hardware Conflict help topic.

Extensive trouble-shooting documentation can be found in the Microsoft

Windows 98 Resource Kit Help File. This help file is part of the Windows

98 Resource Kit, which is available from Microsoft.

Note that if a DOS real-mode driver is in use for a specific device that is

installed in the PC, Windows 98 may not know about that device’s resource

requirements.

There are rare I/O conflict situations of which the Device Manager may be

unaware. Such a conflict may occur when an I/O resource is not properly

specified for a device, and a new driver overlays onto the true I/O space of

that device. In the event of such a conflict, it may become necessary to

manually reserve I/O or IRQ resources using the Device Manager. This

process is described in the Microsoft Windows on-line help.

Once these resources have been reserved, the Device Manager will

recognize and attempt to resolve any resource conflicts between the DOS

driver and any Windows drivers. If a conflict still occurs, it will be visible,

and may be resolved as described in Solving IRQ and I/O Conflicts under

Windows 98 earlier in this chapter.

If a device resource requirement is hardwired into the PC (i.e., configured

by a jumper or not modifiable from the system

BIOS), there is little that the

Windows 98 operating system can do to free the resources.
