Internal Hard Disk Installation
These instructions explain how to replace the internal hard disk.
Make sure you have all the parts necessary for the procedure. The
internal hard disk upgrade kit includes the following:
■ An internal hard disk
■ An antistatic wristband
1. Follow the instructions in “Removing the Controller Board”
(earlier in this chapter), being careful to eliminate static
electricity before you begin.
2. Orient the controller board so that the side with the SIMMs is
closest to you and the parallel port is located on your left side.
3. Disconnect the ribbon cable from the hard disk but leave the
cable attached to the controller board.
