channels and controllers

miniman

Can someone cast a light over the channel/controller issue for me.
I know that for IDE you can have up to 2 devices per controller. Is the channel the whole part i.e all controllers?



Thanks for looking

A standard PC is usually equipped with two IDE controllers ("ATA interfaces" ), a primary and a secondary controller, also referred to as the primary and the secondary IDE channel. Per channel you can connect two devices, hence a standard PC can hold up to four IDE devices in total.
