Resolving Configuration Conflicts
The resources used by the server consist of IRQs, DMA,
I/O port addresses, and memory. This information is
useful when a resource configuration conflict occurs.
Conflicts in the configuration occur if:
A device that you installed 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.
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 only the
system hardware and interrupt requests. The program
does not consider the requirements of the operating
system or the application programs. For these reasons,
memory-address configuration conflicts might occur. You
can resolve some memory-address conflicts by changing
the address of the conflicting hardware option, or by
changing or moving the hardware. You might have to
resolve other memory-address conflicts by changing some
software parameters.
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 the resources that the system board
functions use. Record the current settings before
making any changes. (See “Configuration/Setup
Program” on page 17 for instructions.)
2. Determine which adapter or device is causing the
conflict.
3. Change adapter jumpers or switches. Some devices
use jumpers and switches to define the system
resources that they 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.
