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 chapter, for a list of
the RAM configurations possible.
Before you install the chips, check their pin alignment as described
in step 1 of the previous section. Then follow these steps:
1. Place the expansion board on your work surface with the
components facing up.
2. 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.
