2.4 PCI Configuration
1. Plug and Play:
As a plug and play component, the board requests an interrupt number via
its PCI controller. The system BIOS responds with an interrupt assignment
based on the board information and system parameters. These system
parameters are determined by the installed drivers 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 configuration 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 incorrectly 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.
