ide cables

i read an article on how to put windows xp on a dell latitude laptop with no cd drive and floppy drive. In it, the instruction is refering to ide 1 channel 1 and ide 1 channel 2. my question is that are they refering the channel 1 as being the middle 40 pin plug on the ribon and the channel 2 is the end part of the ide cable

can any one please explain to me


thanks
