1.If you have not already done so, upgrade the BIOS. See “Upgrading the BIOS” on page 1-1 for instructions.

2.Turn off the computer and peripherals, disconnect them from their electrical out- lets, and wait 10 to 20 seconds.

3.If you have a mini-tower computer, lay the computer on its right side.

4.Open the computer cover.

5.Install or remove RIMMs as necessary to reach the desired memory total.

NOTE: For instructions on installing RIMMs, see “Installing a RIMM” on page 1-7. For instructions on removing RIMMs, see “Removing a RIMM” on page 1-8.

6.Install CRIMMs in any RIMM sockets that do not contain RIMMs.

7.If you have a mini-tower computer, stand the computer upright.

8.Close the computer cover, reconnect the computer and peripherals to their power sources, and turn them on.

As the system boots, it detects the presence of the new RIMMs and automati- cally changes the system configuration information in system setup.

NOTES: Adding or removing RIMMs causes the following message to be dis- played at the next system start-up:

The amount of system memory has changed.
