Adapter considerations:
Before you continue with
the adapter-installation procedure:
Ÿ
Review the documentation that comes with the
adapter and follow those instructions in addition to the
instructions given in this chapter. If you need to
change the switch or jumper settings on the adapter,
follow the instructions that come with the adapter
documentation.
Ÿ
You can install a full-length ISA adapter in the ISA
expansion slot.
Ÿ
You can install full-length adapters in all PCI
expansion slots.
Ÿ
You can install hot-plug PCI adapters in PCI slots
1–4, if the operating system supports this feature.
Non-hot-plug PCI adapters can also be installed in
these slots.
Ÿ
The server supports 5.0 V and universal PCI
adapters; it does not support 3.3 V adapters.
Note: A universal PCI adapter supports both 3.3 V
and 5.0 V operation.
Ÿ
The 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.
Ÿ
PCI slots 5 and 6 are on the primary PCI bus and
PCI slots 1–4 are on the secondary PCI bus. The
performance of the PCI adapters depends on the
configuration of adapters in the system.
Plug and Play technology:
Plug and Play is an
ISA technology designed to make expanding the server
easier. Plug and Play adapter support is built into the
system board in the server. If the operating system
supports Plug and Play technology, the server will
