Configuring EISA, ISA, and PCI Adapters
Device Drivers
Device drivers are programs designed to support a specific type of
hardware device. They provide instructions that enable the
computer to interact with the device, or to take advantage of a
device's special feature. The device driver might come with the
operating system, the application program, or on the option diskette.
Not all devices require device drivers. Refer to the documentation
that comes with the option for additional information.
Sample Applications
Some optional devices provide small applications or sampler files.
These applications demonstrate the capabilities of the device and
serve as software examples for programming the device. Refer to
the documentation that comes with the option for additional
information.
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 Configuration Conflicts” on page 43.
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 33). Verify that the IRQ assignments are correct.
Your PC Server 325 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,
see “PCI Bus Control” on page 33.
