the page for PCI says there are two ways of accessing PCI space,
but there are also bios calls for that, which makes things much easier if
you're working in real mode

more information about pci bios calls:

It's a wiki, you can add it yourself.

Here are instructions for getting access to edit the wiki.

But I don't see how the BIOS calls make it any easier, even in real mode. I think detecting the configuration mechanism is the only thing they're good for.

There is a set for accessing the configuration space, but I'm not really sure how standardized/available they were beyond the top-level "does this machine have PCI?" one.
