Probably. Also the BIOS should report what it's using before you even get to the OS.
The 66-cables are stiff, with a blue connector to plug into the motherboard,
reasonably easy to distinguish from normal IDE cables. Also if you look closely
you will see one wire notched out for a length of about 4mm towards one end of the
cable (a hole in the cable.)

Remember to plug a slave drive in the MIDDLE and the master at the END.
Don't leave the end unplugged if the middle connector is used. It didn't used to
matter but now it does, or it could.
