2.4 PCI Configuration
2.4.1 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 drivers and the hardware is acknowledged by the sys-
tem.
2.4.2 Configuration
Board configuration is accomplished on a board-by-board basis
for all PCI/PXI boards in the chassis. 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 sys-
tem as new boards are added or removed.
2.4.3 Troubleshooting
If the system doesn’t boot or you experience erratic operation with
the PCI/PXI board in place, it’s likely caused by an interrupt con-
flict (perhaps the BIOS settings are incorrectly configured). In gen-
eral, the solution, once you determine it is not a simple oversight,
is to consult the BIOS documentation that comes with your sys-
tem.
