Changing the I/O Base Address or the Interrupt Request Level

If you discover that you have a resource conflict, you can change
the I/O base address or the interrupt request level (IRQ). If you are
adding new hardware to your system, you may need to change a
resource assignment to avoid a conflict. The following procedures
describe how to change resource allocations for your Windows 95
or Windows NT PC.

Windows 95

Follow these steps to change the IRQ level assignment or the
I/O base address in a Windows 95 PC:
1 Double-click the My Computer icon, double-click the
Control Panel icon, and then double-click the System icon.
The System Properties window is displayed.
2 Select the Device Manager tab, double-click Network
adapters, and then double-click 3Com EtherLink III ISA
Adapter.
3 Select the Resources tab.
4 Depending on the type of conflict that you have, select
either Input/Output Range or Interrupt Request.
5 Select the resource that you want to change (IRQ or
Input/Output Range) and select Change Settings. (If these
options appear dimmed, clear the Use automatic settings
check box.)
6 Scroll to a value that you know is available, and then
click OK.
You recorded available IRQ values during the Windows 95
preinstallation procedure. See "Performing the Preinstallation
Procedure" in Chapter 2.
Before you reboot Windows 95, make sure that the value that
you assign to a resource matches the value for the same resource
in the NIC Configuration Settings screen (similar to that shown in
Figure 3-2) in the 3Com NIC Diagnostics program.
7 Close all open windows and restart the PC.
The hardware conflict should be resolved. If not, consult your
system administrator.
