IBM modifies the cable so that all drives are to be configured as drive 2
(low = 1). Some of the clone kits followed IBM but most simply use straight
through cables. If the large cable does not have a twist in the middle of it
then it is a straight through cable. There is a jumper or a set of switches
on the drive that must be changed. These are usually located on the back

edge of the drive. 

NOTE: This is not a difference between XT and AT but the difference between
IBM cables and clone cables. This difference occurs on both types of

machines.

REMEMBER:
  If the cable has a twist then configure all drives as the second drive.
  If the cable is straight through then configure each drive differently
    starting with the first drive.
