We call them primary and secondary too, but channels and controllers are
different. A controller is the chip on the *motherboard* that the sockets on
the motherboard connect to. There is one controller in a typical PC --
usually with two (primary + secondary) IDE channels. Each channel can have a
master and a slave device.
If you added another IDE controller card in a PCI slot, you'd have four IDE
channels, for a maximum of eight devices. Of course, special controller
cards might provide even more.
