Installing RAM SIMM Units
- Follow the procedures detailed in ESD Precautions on page 4-1 in the Optima2 User's Guide.
- Open the system as described on page 4-2.
- Check the RAM Expansion Chart for the correct memory configuration.
- Carefully insert a SIMM at about a 45o angle into the socket as shown in Figure 4-8 below:
- Push the SIMM into the socket until it is firmly seated.
- Tilt the SIMM up to a vertical position until the spring-loaded latches lock the card into place.
- Repeat steps 4 through 6 to install additional SIMMs.
- Close the system as described on page 4-3 and power it up. The system will automatically configure the newly installed memory.
- If you wish to see the new memory configuration, enter the BIOS Setup program by pressing the <F1> key before the system boots. You can also type MEM at the DOS prompt, and the size of the system memory will be displayed.
- For more information regarding the BIOS Setup program, refer to Chapter 3.
