Dual Processor Installation
The 320-pin zero-insertion force (ZIF) pin-grid array (PGA) socket accepts the 90-MHz or
100-MHz dual processor upgrade kits. Install the 90-MHz dual processor upgrade kit into
the Image P90E system board ZIF socket. Install the 100-MHz processor upgrade kit into
the Image P100E system board ZIF socket. Make sure the second processor runs at the
same speed as the first (you cannot, for example, install a 90-MHz upgrade kit into the
Image P100E).
CAUTION:
Heatsinks are required for dual
processors. Heatsinks are available through
NEC.
Install a dual processor into the system board as follows.
1.
Remove the top cover and any expansion boards covering the dual processor
socket as previously described.
Turn the system unit on its side for easier access to the interior of the system.
2.
Locate the dual processor upgrade socket and jumpers J33 and J34 on the system
board (see Figure Section 3-4).
You may have to tag and disconnect any cables blocking access to the jumpers.
