16 Getting Started
2.6 PCI Configuration
1. Plug and Play:
As a plug and play component, the card requests an
interrupt number via its PCI controller. The system BIOS
responds with an interrupt assignment based on the card
information and on known system parameters. These
system parameters are determined by the installed driv-
ers and the hardware load seen by the system.
2. Configuration:
The board configuration is done on a board-by-board
basis for all PCI boards on your system. Because config-
uration is controlled by the system and software, there is
no jumper setting required for base-address, DMA, and
interrupt IRQ.
The configuration is subject to change with every boot of
the system as new boards are added or removed.
3. Trouble shooting:
If your system doesn’t boot or if you experience erratic
operation with your PCI board in place, it’s likely caused
by an interrupt conflict (perhaps the BIOS Setup is incor-
rectly configured). In general, the solution, once you
determine it is not a simple oversight, is to consult the
BIOS documentation that comes with your system.
