I was wrong in asking about the number of pins. That's always 40:
No your weren't. Did you not read my post?

It's the number of wires the cable is made of that can be either
40 or 80.
Of course, the cable doesn't care about the speed.
Wrong. The cable does 'care' about speed.
The speed is determined by the controller and/or the device.
Yes it is, but also by the cable.
If either one of them only speaks ata100, then the transfer is not
going to happen at 133. But I can still attach an ata133 disk to an
ata100 motherboard controller, if I so wish.
Yes you can, but use 80-pin cable otherwise it'll only work at ATA33.
