Installing chip sets on the controller board
The RAM chip sockets are located on the upper right side of the
controller board.
There are two sectors on the board, each containing four chip
sockets (identified by their
IC
numbers), as shown below.

CAVIION:
You cannot install a
zMB
chip set on the
controller board: you can only use the SMB chio sets.
Follow these steps to install a memory chip set:
Make sure all the pins on the chip are aligned. They should
point inward at slightly less than a
90’
angle, as shown below.

If any of the pins are bent incorrectly,
gentiy
push them back
into alignment.
Line up the pins on the RAM chip with the holes in the
socket. Be sure that the small notch on the end of the chip is
toward your right.
3.
Gently press the chip halfway into the socket. If it goes in at
an angle, remove it with a chip puller or a small flat-head
screwdriver; then reinsert the chip.
CAUTION: Be careful not to scratch the chip or the
board when removing the chip.
4. Once the chip is properly inserted, push down firmly on
both ends to make sure it is fully seated.
5.
Repeat steps
1
through
4
for each of the remaining chips.
6. Reinstall the interface card, if necessary.
Installing chip sets on the memory expansion board
There are four sectors on the memory exp,ansion board, each
containing four chip sockets (identified by their IC numbers).
The four sectors must be filled in alphabetical order. For example,
if you are installing your first chip set, install it in sector A. Then
install your next chip set in sector B and so on. See the table under
“Selecting a memory option,” earlier in this section. for
a
list of
the RAM configurations possible the memory expansion board.
Before you install the chips, check their pin alignment as described
in step 1 of the previous seclion. Then follow these steps:
1.
2.
Place the expansion board on your work surface with the
components facing up.
Align the chip’s pins with the holes in the socket. Be sure the
small
notch on the end of the chip is facing in the direction
shown below.
