Many webpages talk about enumerating the PCI bus, scanning through all
devices on each bus, etc. But what is the main point of Enumerating
the PCI? What is my operating system supposed to accomplish by
enumerating the PCI? Am I supposed to store a huge array in memory
with each bit or every few bits representing a slot in the PCI and
record each slot's status (i.e. whether there is a device there or
not)? Or is the point the enable bit?
Thank you,
