2.4 PCI Configuration
1. Plug and Play:
As a plug and play component, the board requests an interrupt number via a
system call. The system BIOS responds with an interrupt assignment based on
the board information and on known 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 form
factor boards on your system. Because configuration is controlled by the
system and software, so there is no jumpers for base-address, DMA, and
interrupt IRQ need to be set by the user.
The configuration is subject to change with every boot of the system as new
boards are added or boards are removed. So, there is no idea what‘s going on
to be installed.
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 because you
incorrectly configured the BIOS setup). In general, the solution, once you
determine it is not a simple oversight, is to consult the BIOS documentation
that came with your system.
