between sockets. The minimum memory size is 128 MB. The
maximum memory size is 1 GB. The BIOS automatically detects the
type, size and speed of the memory modules.

If necessary, remove the memory module you wish to replace (see
“Removing a Memory Module” on page 35).

Remove the new memory module(s) from its anti-static package.
Hold the memory module only by its edges to prevent static-
electricity damage.

Remove the power supply (see “Removing the Power Supply” on
page 48).
