PCI Features and Options:
PCI devices automatically communicate with the server's
configuration information. This usually results in automatic
configuration of a PCI device. If a conflict does occur,
refer to “Configuration Conflicts” on page 30.
Multiple-function PCI adapters use more than one interrupt.
When installing one of these adapters, IRQ assignments
should be reviewed in the Configuration/Setup utility
programs to assure the IRQ assignments are correct.
The PC Server 325 automatically configures PCI adapters.
This enables the installation of a variety of PCI adapters
that currently do not support sharing of PCI interrupts. For
information on manually overriding the interrupt, see
“Advanced Setup” on page 33.
Configuration Conflicts
The resources used by a server consist of interrupt request
levels (IRQs), direct memory access channels (DMAs), I/O
ports, and memory. This information is useful when a
resource configuration conflict occurs.
Conflicts in the configuration occur if:
Ÿ
A device is installed that requires the same resource
as another device. (For example, if you install an ISA
network adapter and an EISA network adapter, both
requesting
IRQ 5, only one of the adapters can be
configured.)
Ÿ
A device resource is changed (for example, changing
jumper settings).
Ÿ
A device function is changed (for example, assigning
COM 1 to two different serial ports).
Ÿ
An installed software program requires the same
resource as a hardware device (for example, an
expanded memory specification (EMS) device driver
that uses the address required by the SVGA video
adapter).
The steps required to resolve a configuration error are
determined by the number and variety of hardware devices
and software programs installed in the system.
If a hardware configuration error is detected, a
configuration error message appears after the server
completes POST, but before the operating system starts.
You can bypass the error or start one of the configuration
utility programs. Use the up and down arrow keys (
↑
and
↓
) to select Continue or Exit Setup, then, press Enter.
Continue will start the Configuration/Setup Utilities
program. Exit Setup will bypass the error and load the
operating system. You can also press Esc to exit setup
and load the operating system. To start the EISA
Configuration Diskette, insert the diskette in the diskette
drive and press Esc.
