If you can find one that is otherwise I am sure a lot of us would like to see that ugly duckling just for proof it exists. As Claude says, when using a CS cable jumper the drives CS and when not using a CS cable jumper them master/slave. For me that ALWAYS works in every config. The only caveat I have is that generally CDROM/DVDROM devices should never be master to a hard disk so that should be remembered when installing devices/cables. Otherwise CS settings just work. > If one must use a Cable Select cable for only one device and it doesn't > seem to work quite right at either position, I suppose one could just cut > the cable after the middle connector, which would make it the end > connector.
