Multiple-function			PCI	adapters use more than one interrupt. When you	insta

Your Netfinity 5000 server uses a rotational interrupt technique to confi adapters. This technique enables you to install a variety of PCI adap currently do not support sharing of PCI interrupts. For information on manu overriding the interrupt setting, see “PCI Bus Control” on page 29.

Resolving Configuration Conflicts

The resources used by your server consist of IRQs, DMA, I/O port a memory. This information is useful when a resource configuration conflict

Conflicts in the configuration occur if:

ŸA device is installed that requires the same resource as another example, a conflict occurs when two adapters try to write to the space.)

Ÿ A device resource is changed (for example, changing jumper settings

Ÿ A device function is changed (for example,COM1 toassigningtwo serial ports).
