72All Installation CDs allow you to boot, set up networking, initialize your
73partitions and start installing Gentoo from the Internet. We currently provide
74two Installation CDs which are equally suitable to install Gentoo from, as long
75as you're planning on performing an Internet-based installation using the
76latest version of the available packages.
77</p>
78
79<p>
80If you wish to install Gentoo without a working Internet connection, please use
81the installation instructions described in the <uri
82link="2008.0/index.xml">Gentoo 2008.0 Handbooks</uri>.
83</p>
84
85<p>
86The two Installation CDs we currently provide are:
87</p>
88
89<ul>
90 <li>
91 The Gentoo Minimal Installation CD, a small, no-nonsense, bootable CD which
92 sole purpose is to boot the system, prepare the networking and continue
93 with the Gentoo installation.
94 </li>
95 <li>
96 The Gentoo Universal Installation CD, a bootable CD with the same abilities
97 as the Minimal Installation CD. Additionally, it contains several stage3
98 tarballs (optimized for the individual subarchitectures).
99 </li>
100</ul>
101
102<p>
103To help you decide which Installation CD you need, we have written down the
104major advantages and disadvantages of each Installation CD.

146and consumes about 316 MB on a CD. You can use this Installation CD to install
147Gentoo, and you can even use it to install Gentoo without a working internet
148connection, just in case you want to bring Gentoo to another PC than the one
149you are currently installing Gentoo on :)

180You might find a Package CD on one of our mirrors. This CD is not an
181Installation CD but an additional resource that can be exploited during a
182networkless installation. It contains prebuilt packages (also known as the GRP
183set) that allow you to easily and quickly install additional applications
184(such as OpenOffice.org, KDE, GNOME, ...) immediately after the networkless
185Gentoo installation.
186</p>
187
188<p>
189If you intend to use the Packages CD to quickly install additional software,
190make sure that you use the same subarchitecture as the stage3 tarball you use.
