Hi,
I've been looking around for a few weeks playing around with the idea of PCI [E].

I have searched everywhere [OSDev, google, SIG, intel] to no avail of finding any information on how to use PCI [E] with an intel processor.

It would be great if someone could point me in the right direction[specifications, sample code, advice].

I am sorry if I am asking a stupid question.
Thanks in advance.

Are you joking?
1. PCI isn't specific for x86, you can find PCI bus on non-x86 machines and it would be the same PCI.
2. You can start from wiki: http://wiki.osdev.org/PCI , http://wiki.osdev.org/PCI_Express (one can find link to corresponding specification at the end of wiki page, although official PCI specs are very long).
