First remove the internal drive mounting bracket in your
computer; see "Removing the Drive Mounting Bracket" in
Chapter 5 for instructions.
Locate the external cache memory sockets as shown in the
illustration under "Locating the System Board
Components."
Remove any option cards that are blocking access to the
sockets; see "Removing an Option Card" for instructions.
Caution
To avoid generating static electricity and damaging the
cache chips, ground yourself by touching the metal
surface on the inside of the computer's back panel. Then
remain as stationary as possible while you install them.
