I suppose you mean theses Jumpers just beside of the connections at the rear...
These ones are made to set the ID-Number, and normally, there arent usefull.
On the left, (right ?) is ID 0 (drive C:) on the right (left?) ID 3 (Drive F:).
As you can only use two hard-drives in you AT, you can jumper ID 0 and ID 1.
But normally, a cable with three connection, wich is splitted at one end, and
where are some cables turned, is used to connect two hard-drives....

So you only have to look whetather there is a jumper, or not. If not, your
drive will not work....

Hoping this helps you..

CU, Markus
