Upgrade Guide
This section explains how to install options on your mainboard.
It covers the most likely and technically accessible upgrades you
might want to do, including adding expansion cards, increasing sys­
tem memory upgrading the BIOS.
Installing upgrades will either improve the performance of your
computer, or add some additional capabilities to it. You can install
upgrades yourself, or have your dealer or a qualified computer tech­
nician do it for you.
It is also possible to increase the size of the Level 2 cache for the
SRAM cache model, but since this is a much more technically de­
manding upgrade that you are both less likely to undertake, and in
most cases would probably require at least partially disassembling
your system, the technical reference information about this is in Chap­
ter 4. It is probably best to have a qualified technician perform the
upgrade for you if you want to upgrade the cache.
