2. To release a memory module from its socket, carefully spread apart          
the inner tabs of the memory module socket just far enough for the 
memory module to disengage from the socket (it should pop up slightly)                
(see Figure 8).
3. Lift the memory module out of its socket.
If you only have one memory module, install it in the DIMM A socket. Memory 
modules are keyed, or designed to fit into their sockets, in only one direction. 
The slots on the system board are notched so that the memory module can be 
firmly seated only one way.
Align the memory module’s edge connector with the slot in the center of the 
memory module socket. With the module at a 45-degree angle, press the 
memory module’s edge connector firmly into the memory module socket. 
Pivot the memory module down until it clicks into place. If you do not hear a 
click as each end of the memory module snaps into the tabs, remove the 
memory module and reinstall it.
NOTE: 192-MB memory modules are designed for either the socket labeled 
DIMM A or the socket labeled DIMM B; they are not interchangeable. Be sure 
that the memory module is inserted with the double-stacked memory chips 
facing you. A 192-MB memory module inserted with the double-stacked 
memory chips facing down does not fit properly in the socket.
