Upgrading components in your system unit yourself, can be a rewarding but challenging experience. If you decide to take this road keep the following points in mind:

If you don't understand the instructions, call an expert for advice. Your friendly local computer store is just a phone call away.

You may have to change a dip switch from on to off, or move a jumper from one pin to another.
