How do I decipher PCIRoot in config.plist>Root>DeviceProperties>Add?

[joeyslaptop]

I assume that the following default code is a PCI-slot address or something, but I can't find much info on it.

PciRoot(0x0)/Pci(0x1b,0x0) = Dictionary
layout-id = <01000000>

What is this (in simple terms)? How do I construct entries in this section? Do I do one for each PCI port?

----------Info-----------
I found this command in Linux that appears to provide good info: sudo dmidecode -t baseboard

You can just leave it alone. You can use this section to put in a Custom power play table for your and graphics card, which is what I did. I'm sure it has other uses too.
