Slightly Off Topic .......

Are there any good online resources that describe in detail how Fedora [or Linux in general] probes the PCI bus for cards and bridges, then sets them up for use? From the references I have found, it is not clear to me if the motherboard BIOS does the probing (i.e. identifying what cards/functions are on what bus) then configuring the base address registers; or, if some, or all, of this is done under Linux.

Any references will be greatly appreciated!!

Thanks!
