Plug and Play:
Most adapters designed for PCI slots
are Plug and Play devices that are auto-configuring.
However, many ISA adapters are not Plug and Play
devices and you must allocate the system resources that
the adapter will use. Select Plug and Play to identify the
available system resources:
Ÿ
Memory
Ÿ
I/O ports
Ÿ
DMA
Ÿ
Interrupt
Note
The menus do not contain resources that are used by
the system or by previously installed Plug and Play
adapters.
Select Plug and Play; then, use the Up Arrow (
↑
) and
Down Arrow (
↓
) key to highlight the system resource that
you want to change. Use the Left Arrow (
←
) or Right
Arrow (
→
) key to toggle from Plug and Play to ISA
Legacy for the selected menu choice.
Error log:
Select Error Log to view the three most
recent power-on self-test (POST) errors the system has
generated, or to view the system error log. You can clear
both error logs from this screen by selecting Clear Error
Logs.
Configuring PCI features and options:
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 resource conflicts” on page 50.
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 bus control” on page 30). Verify that the IRQ
assignments are correct.
The Netfinity 5000 server 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. For
information on manually overriding the interrupt setting,
see “PCI bus control” on page 30.
