Resolving configuration conflicts
The resources used by the server consist of interrupt
requests, direct memory access, I/O ports addresses, and
memory. This information is useful when a resource
configuration conflict occurs.
Conflicts in the configuration occur if:
Ÿ
A device is installed that requires the same resource
as another device. (For example, a conflict occurs
when two adapters try to write to the same address
space.)
Ÿ
A device resource is changed (for example, changing
jumper settings).
Ÿ
A device function is changed (for example, assigning
COM1 to two serial ports).
Ÿ
A software program is installed that requires the same
resource as a hardware device.
The steps required to resolve a configuration error are
determined by the number and variety of hardware devices
and software programs that you install. If a hardware
configuration error is detected, a
configuration error
message appears after the server completes POST and
before the operating system is loaded. You can bypass
the error by pressing Esc while the error message is
displayed.
The System Configuration Utility program configures the
system hardware and PCI IRQs. The program does not
consider the requirements of the operating system or the
application programs. See “Resolving software
configuration conflicts” on page 40 for additional
information.
Resolving hardware configuration
conflicts:
Use the following information to help resolve
hardware configuration conflicts:
1. Run the System Configuration Utility program to view
and change resources used by the system functions
and the installed options. Record the current settings
before making any changes. (See “The System
Configuration Utility program” on page 25 for
instructions.)
2. Determine which adapter or device is causing the
conflict. (Go to “General checkout” on page 6.)
3. Change adapter jumpers or switches. Some devices
use jumpers and switches to define the system
resources that the devices need. If the settings are
incorrect or set to use a resource that cannot be
shared, a conflict occurs and the device will remain
deactivated by the configuration program.
4. Change system jumpers or switches. See “Changing
jumper positions” on page 164.
