Device Conflict on a Windows System
7-24
A conflict can still occur even after using the Windows NT Diagnostics program to
determine unused I/O port addresses and IRQ values. This can happen when your computer
has one or more devices and/or peripherals installed that claimed an I/O Base Address or
IRQ value without notifying the Windows NT operating system. Therefore, the Windows
NT Diagnostics program does not display these values as used.
If there is a device conflict, select alternative settings for I/O Base Address or IRQ values.
You may need to try multiple values before resolving the problem. To isolate the problem,
you should change only one parameter at a time. For example, try to resolve a possible
conflict with the I/O Base Address. If that does not work, try to resolve a possible IRQ
conflict.
If you know which device is conflicting with the PC Card, you have the option of changing
that device’s I/O address or IRQ instead of changing the RoamAbout PC Card or ISA card.
Depending on the computer, you might need to verify the settings of the BIOS which is
loaded when you start your computer.
If the computer previously had a network card installed and the network card w as run ni ng
in 32-bit operation, you may need to set the BIOS to PCIC - 16 bit. You may also need to
disable the network card in the Control Panel - Devices.
Windows 95 or 98
To check the I/O and IRQ for a Windows 95 and 98 system:
1. From the Taskbar, click Start then select Settings→Control Panel.
2. Double-click the System icon.
3. Select the Device Manager tab.
4. Open (click the + sign) Network adapters, select RoamAbout 802.11 DS, then click
the Properties button.
5. Click the Resources tab to see the I/O range and IRQ setting.
You can also select a different device and click Properties to display its resource settings.
Should you change the I/O address or IRQ value, only change one value at the time to
isolate a potential conflict without unintentionally creating another one.
Depending on the computer, you might need to verify the settings of the BIOS which is
loaded when you start your computer.
