Cable Select doesn't work on the empeg if I remember correctly. I've never used it so chances are you only lost that one jumper.

Technically, Drive 0 should be at the end of the cable (read that here years ago) and Drive 1 should be on the slot closer to the board.

Just try it one way and see if it initiates a database rebuild (or, another indicator would be if the player boots up with an older version of the player software. Software updates only get applied to the Drive 0.). If it does, you put it on the wrong drive. Just unplug and try it the other way.
