3 Adding Memory
In the future you may want to install a memory module to expand the
functionality of your computer. For this model, 128 MB of memory is pre-
installed (64 MB on the motherboard and 64 MB in the memory module
bay). You can increase memory up to 192 MB by replacing the 64 MB in
the memory module bay with a 128 MB memory module. Expansion
memory modules are available as options. For memory upgrades, use
only PC-100 SDRAM SO-DIMM (gold lead contacts).
