They're still all on one bus no matter how many ide connections
you have, the one and only PCI bus. Generally the only 'rule' is
to not to put a CD drive (or CD-RW), on the same cable as a HDD.
So if you have 2 HDD's, and one or more CD drives, the HDD's go on
ide0, and the CD drive(s) on ide1. Some report adding another
controller (not onboard), and separating all the drives, one to a
ide channel, improves performance. Still, they're all on the one
PCI bus.
The PCI bus is ancient in computer terms, over 10 years since it
replaced the VL-bus. There's improvement on the horizon. Several
competing scenarios, but the one that seems to be gaining the most
favor is PCI-X, or sometimes called PCI Express. Still the gain is
only from PCI's theoretical 133mb/sec, to 200mb/sec. Real world
sustained transfers are at best half the theoretical rate, usually
much less than half. The PCI bus has other duties besides handling
all ide connections.
