Configuration Conflicts
Resolving Software Configuration Conflicts
The memory-address space and interrupt levels (IRQs) used by
some hardware options might conflict with addresses defined for
use through application programs or the EMS. (EMS is used only
with DOS.)
If a conflict exists, one or more of the following conditions might
exist:
The system cannot load the operating system.
The system does not work.
An application program does not operate, or it returns an error.
Screen messages indicate a conflict exists.
You can resolve conflicts by changing either the software or the
hardware configuration.
Note: Start the Configuration/Setup utility program to view the
addresses used by your system board functions.
Changing the Software Configuration
The best way to resolve memory-address conflicts is to change the
addresses used by the application program or the device driver.
This can be done by using the Configuration/Setup utility program.
If a device driver is causing a memory-address conflict, refer to your
operating-system documentation or the documentation supplied
with the device drivers.
Interrupts
When you assign interrupt levels, remember that high interrupt
level devices have the lowest priority in the processing queue. For
best performance results, assign a low interrupt level to a high
performance device. For example, you might assign interrupt level
10 to an Ethernet PCI LAN adapter.
When you assign a very high interrupt to a high performance
device, performance can be adversely affected.
Note: Interrupt Level 12 is reserved for the mouse.
