NOTICE: You must position the
microprocessor chip correctly in the socket to avoid permanent damage to the chip and the
computer when you turn on the computer.
Install the microprocessor chip in the socket.
If the release lever on the microprocessor socket is not
fully extended, move it to that position now.
With the pin-1 corners of the chip and socket aligned,
align the pins on the chip with the holes in the socket.
NOTICE: When you place the
microprocessor chip in the socket, be sure that all of the pins go into the corresponding
holes on all sides of the socket. Be careful not to bend the pins.
Set the chip lightly in the socket and make sure all
pins are headed into the correct holes. Because your computer uses a ZIF microprocessor
socket, there is no need to use force (which could bend the pins if the chip is
misaligned). When the chip is positioned correctly, press it with minimal pressure to seat
it.
When the chip is fully seated in the socket, pivot the
microprocessor-socket release lever back toward the socket until it snaps into place,
securing the chip.

All IDE devices require that you configure the cable select setting, which assigns
master and slave status to devices according to their position on the interface cable. You
usually configure a drive for cable select by setting a jumper or switch, depending on the
drive. Refer to the drive documentation in your upgrade kit for information on configuring
devices for the cable select setting. When you connect two IDE devices to a single IDE
interface cable and configure them for the cable select setting, the device attached to
the last connector on the interface cable is the master or boot device (drive 0), and the
device attached to the middle connector on the interface cable is the slave device (drive
1).
With the two IDE interface connectors on the system board, your computer supports up to
two IDE devices. IDE hard drives should be connected to the IDE interface connector
labeled "IDE1." (Always connect CD drives to the IDE interface connector labeled
"IDE2.")
When you install a drive, you connect two cables—a DC power cable and an interface
cable—to the back of the drive. Your drive's power input connector (to which you
connect the DC power cable) resembles the following connector.
Power Cable Connector
1
Power cable
2
Power input connector
The drive's interface connector is a card-edge connector or a header connector, as
shown in the following figure.
Drive Interface Connectors
1
Header connector
2

Interface cable
When you attach the interface cable to a drive, be sure to match the colored stripe on
the cable to pin 1 of the drive's interface connector. For the location of pin 1 on the
drive's interface connector, see the documentation that came with the drive.
When you disconnect an interface cable from the system board, be sure to press in on
the locking tabs on the cable connector before you disconnect the cable. When you attach
an interface cable to the system board, be sure that the locking tabs snap into place so
that the cable is firmly attached to the connector on the system board.
Most interface connectors are keyed for correct insertion; that is, a notch or a
missing pin on one connector matches a tab or a filled-in hole on the other connector.
Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored stripe
along one edge of the cable) goes to the pin-1 end of the connector. The pin-1 end of a
connector on a board or a card is usually indicated by a silk-screened "1"
printed directly on the board or card.
NOTICE: When you connect an
interface cable, do not reverse the interface cable (do not place the colored stripe away
from pin 1 of the connector). Reversing the cable prevents the drive from operating and
could damage the controller, the drive, or both.
CAUTION: To avoid the
possibility of electric shock, turn off the computer and any devices, disconnect them from
electrical outlets, and then wait at least 5 seconds before you open the computer cover.
Also, before you install a drive, see the other precautions in "Safety Instructions."
If you are replacing a hard drive that contains data you
