Installing Upgrade CPUs
The 586OP is equipped with a 273-pin Zero Insertion
Force (ZIF) socket at location U32 of the system board.
This socket has a latching/unlatching mechanism that is
located on the right hand side of the ZIF socket (Socket
4). The socket must be in the pen position before you
can install the CPU.
To unlatch (open) the socket, lightly press the ZIF
socket handle down while moving it horizontally to the
right. After the handle is freed from the locking tab,
move it to the highest vertical upright position. IF the
ZIF socket lever action is obstructed or prevented from
extending to his fully open position, damage may occur
to the CPU during removal/installation.
To install the CPU, line up pin 1 of the CPU to pin 1 of
the ZIF socket. (The CPU has one notched edge and that
is the edge where pin 1 is located.) Place theCPU on
top of the ZIF socket assuring that the CPU is level and
has made contact with the pin holes. To relatch the ZIF
socket, move the ZIF socket handle down to its lowest
vertical position. Once in this position, lightly press the
handle down and move it horizontally to the left
catching it under the locking tab.
If the handle is not completely latched, damage to
theCPU or motherboard may result..
Warning:
Open the socket only if actually installing a CPU. The
warranty on the original CPU will be voided if the S/N
seal is broken. Installation of an OverDrive
TM
Processor
will not affect the original system warranty.
