Resolving Hardware
Conflicts
Hardware conflicts may occur when two or more peripheral devices are set to use the same I/O
address, IRQ line or DMA channel. This section provides ways to resolve hardware conflicts
❑
In Windows 95/98
❑
In Windows 3.1x
In Windows 95/98
To resolve conflicts in Windows 95/98, change the resource settings of your modem or the
conflicting peripheral device in your system using Device Manager.
To run Device Manager:
1. Right-click the My Computer icon on your Windows 95/98 desktop, and then select
Properties.
2. In the System Properties dialog box, click the Device Manager tab.
A list of system devices is displayed.
3. Double-click the Modem icon.
4. Select your modem, and then click the Properties button.
5. In the Properties dialog box, click the Resources tab.
6. Select the Use Automatic Settings check box.
If this check box is already selected, you need to go to the Properties dialog box of the
conflicting peripheral device and select the same check box there.
7. Reboot your system to allow Windows 95/98 to reassign resources to your modem and/or
the conflicting peripheral device.
In Windows 3.1x
1. Find a COM port and IRQ that are unused in your computer.
2. Adjust the jumper settings of the Modem Blaster to that of the unused COM port and IRQ.
If you are unsure of the settings
of any conflicting peripheral
devices, you can isolate the
source of the problem by
temporarily removing all devices
(except your modem and
essential devices such as the disk
controller). After that, add the
devices back one at a time until
the device that is causing the
conflict is found.
