PCI Device Configuration
Overview
As plug and play component, a PCI card automatically
requests an interrupt number through its PCI controller. The
system BIOS responds with an interrupt assignment based on
the card information and any known system parameters. These
system parameters are determined by the installed drivers and
the hardware load detected by the system.
Configuration
Board configuration is done on a board-by-board basis for all
PCI boards on your system. Because configuration is con-
trolled by the system and the software, there are no jumper set-
tings required for base addresses, DMAs, and/or interrupt
IRQs.
Configuration is subject to change with every boot of the sys-
tem as new boards are added or removed.
Troubleshooting
If your system fails to boot or if you experience erratic opera-
tion with your PCI board installed, this is likely caused by an
interrupt conflict (i.e. the BIOS Setup is incorrectly configured).
Refer to the BIOS documentation that came with the system for
details.
