How to Install, Upgrade, and Update Software

[b]Using CD #2 as a Source[/b] Software may be installed from MEPIS CD #2. This software was placed on CD at the same time CD #1 was created, therefore it should be fully compatible with the software on CD #1. However once you have updated or upgraded from the Internet, you may find that it is no longer possible to install some of the software from CD #2. [b]Using the Internet as a Source[/b] Software may be installed or updated from the Internet. This software is the most up-to-date, but it may be less stable than the software you already have.
