Resolving configuration conflicts
The resources used by your 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:
Ÿ
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.)
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 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,
