"If you've ever spent any time playing with ix86 hardware, you
know that populating a system with a full complement of PCI and AGP
hardware can be a nightmare. Interrupt conflicts, base address
conflicts, master and slave PCI slots versus master and slave PCI
cards... It's a complex issue indeed."
"Luckily, Linux provides several ways for you to become more
acquainted with the details on your PCI devices. Try this
$ cat /proc/pci | lpr
Your printer will spit out one of the most detailed and useful
reports on your PCI bus and PCI hardware..."
"If you have multiple PCI busses or high-end PCI cards with PCI
bridges and multiple PCI devices on each, you may find the tree
view helpful as well:
$ /sbin/lspci -t -v | lpr
This kind of detailed PCI information is especially helpful if
you're not just running Linux, but are trying to multi-boot several
operating systems and get all of your devices working in each one."
