1.
Locate the memory chip sockets on the main system board,
shown on page 3-5.
Bank 0 (labeled
U24
and
U40)
contains two chips soldered to
the system board, so you cannot add video memory in this
bank. Bank 1
(U25
and
U41)
contains the two sockets closest
to the soldered chips. Bank 2
(U32
and
U46)
is the two
middle sockets in each set of three and Bank 3
(U33
and U47)
contains the remaining two sockets.
2. If there is an option card in your way, remove it. See page
3-16 for instructions.
Caution
To avoid generating static electricity and damaging the
memory 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.
3.
Remove the memory chips from their package and inspect
each one. The pins should point inward at slightly less than
a 90° angle.
If any of the pins are bent, straighten them gently with your
fingers or with small tweezers to align them with the other
pins. Be careful when you do this; the pins are fragile and
can break off easily.
