You can also think of "rdisk()" as meaning the

Yes, that's a interpretation (of course, the original
meaning in 1992 was neither real not relative).

Since the boot order

Bewa that's not the "boot order" (another thing entirely),
but the order among the harddisks (int13h non removable
devices).


Yes. I usually refer specifically to "hard drive boot order",
but twice in short sequence seemed a bit much, so I
shortened it to "boot order" in the next sentence, thinking
that the implied sub-phrase "hard drive" was understood.
You point out an important point, because the "x" in
"rdisk(x)" refers to position in the "hard drive boot order",
not simply to the "boot order" - which includes other
bootable devices besides hard drives.
