You seem to be confusing AT/IDE with SCSI. There is optional "termination" in IDE, because the controler is resident on the drives. It does not matter which drive is where on the cable. (unless there's a twist in the cable--see below.)
>If you have only one drive attached, it should be configured as master, >otherwise the cable is not terminated. (and it can sit anywhere on the >cable).
Actually, the reason that "one drive" must be master, is because the "master" is the one that runs the controller logic. There has to be "one" controller.

In some drives, if the "cable select" option is enabled, you can configure the drive number with a twist in the cable, like on PC floppies. This is only available on some IDE drives.
