The book arrived today, and I now understand a *lot* more about PCI than I did previously. Thanks again! This might not be the place for these things, but if you don't mind spending a little time on me, there's still something I don't quite understand in relation to VGA legacy address decoding. Namely, how does the system select which card is supposed to do legacy decode? Since it is usually selectable in the system BIOS UI which card should be initialized as _the_ VGA card in the presence of multiple VGA-compatible cards, there has to be some standardized way of enabling legacy decode on a card, right? I just can't find what that way is. My naive guess is that it might be that the system BIOS only calls the VGA BIOS code for the selected card, and it sets up legacy decode in a card-specific way, but I can just find no way to confirm that, and I've been googling for quite some time now.
