My old computers are packed away at the moment, but as I reacall there is
a jumper or dip swith block for drive select (usually silkscreened on the 
printed circuit as DS0.DS1.DS2.DS3 (or sometimes starting with 1 vice 0).
The other item is terminating resistors, which are usually a DIP or SIP 
pack near the drive select jumpers.  The terminating resistors need to be on
the drive at the END of the cable.  

This was before IBM created the abomination of inserting a twist in the 
drive cable to avoid having to set the jumpers.
