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 system 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 technician 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 demanding 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 Chapter 4. It is probably best to have a qualified technician perform the upgrade for you if you want to upgrade the cache. 2 - 1
