Installing DRAM SIMMs
When you install DRAM SIMMs, make sure that the SIMMs are the same size.
For example, you can install two 2-MB by 36 SIMMs for a 16-MB configuration;
however, do not install one 1-MB by 36 and one 2-MB by 36 SIMM.
Also, make sure that you are using the correct capacity Tag SIMM for your
DRAM configuration (refer to T
able 2-2).
You must first install the SIMM closest to the back of the CPU.
To install a DRAM SIMM:
1. Grasp the SIMM by the top corners, and place it into the connector at a
slight angle.
The SIMM is keyed to fit in the connector only one way (F
igure 2-4).
