Resolving configuration conflicts

The resources used by your server consist of interrupt requests, direct memory
access (DMA), I/O ports addresses, and memory. This information is useful when
a resource configuration conflict occurs.
Conflicts in the configuration occur if:
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 Configuration/Setup 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 33 for additional information.

Resolving hardware configuration conflicts

Use the following information to help resolve hardware configuration conflicts:
1. Run the Configuration/Setup Utility program to view and change resources
2. Determine which adapter or device is causing the conflict. (See Chapter 6,
3. Change adapter jumpers or switches. Some devices use jumpers and switches

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.)
A device resource is changed (for example, changing jumper settings).
A device function is changed (for example, assigning COM1 to two serial ports).
A software program is installed that requires the same resource as a hardware
device.
used by the system functions and the installed options. Record the current
settings before making any changes. (See "The Configuration/Setup Utility
program" on page 20 for instructions.)

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.
