Working with options on the system board
This section provides instructions for installing options, such as system
memory, on the system board.
Accessing the system board
To access the system board, you must remove the computer cover. For
information on removing the computer cover, see “Removing the cover —
desktop model” on page 55 or “Removing the cover — tower model” on
page 56, depending on your computer model. You might need to remove
adapters in order to access some components of the system board. For
information about expansion adapters, see “Working with adapters” on
page 68. When disconnecting cables, be sure to note where they attach, so
you can correctly reattach them later.
Note: For easier access to the system board, it helps to place the computer
on its side on a table.
Identifying parts on the system board
The system board, also called the planar or motherboard, is the main circuit
board in your computer. It provides basic computer functions and supports
a variety of devices that are IBM-installed or that you can install later.
Refer to the following illustration for the location of parts on the system
board.
Note: An illustration of the system board and additional information is
provided on a label located on the inside of the computer chassis.
