Configuring ISA and PCI Adapters
You cannot assign an ISA adapter to the same interrupt
that you have assigned to a PCI adapter. This is because
the Netfinity 5500 does not support interrupt sharing
among PCI and ISA adapters.
If a situation occurs where you need an additional
interrupt, you can use an interrupt from another function
that you might not need, such as COM2 (Interrupt 3).
To configure ISA adapters, select Plug and Play and
follow the instructions on the screen. See 'Plug and Play'
and 'Plug and Play Technology' for additional information.
PCI devices automatically communicate with the server
configuration information. This usually results in automatic
configuration of a PCI device. If a conflict does occur, see
'Resolving Configuration Conflicts'.
Multiple-function PCI adapters use more than one interrupt.
When you install one of these adapters, review the IRQ
assignments in the Configuration/Setup Utility programs
(see 'PCI Routing'). Verify that the IRQ
assignments are correct.
the Netfinity 5500 uses a rotational interrupt technique to
configure PCI adapters. This technique enables you to
install a variety of PCI adapters that currently do not
support sharing of PCI interrupts.
