Point
• For this PC, the number of pins in a cable differs between those connected to the primary and
secondary IDEs. Use a 80-pin cable for connection to the primary IDE and a 40-pin one for
connection to the secondary IDE.
• By default, the pre-installed internal IDE device is configured to Cable-Select.
• Be sure to connect the hard disk that runs OS to the primary IDE connector as a master. If it is
connected as a slave or to the secondary IDE connector, OS may not run.
• For combination of the “master” and “slave” of the secondary IDE, refer to “Installing front access
bay options”.
