Before we start, we first list what hardware requirements you need to successfully install Gentoo on your box.

The Gentoo Installation CDs are bootable CDs which contain a self-sustained Gentoo environment. They allow you to boot Linux from the CD. During the boot process your hardware is detected and the appropriate drivers are loaded. They are maintained by Gentoo developers.

All Installation CDs allow you to boot, set up networking, initialize your partitions and start installing Gentoo from the Internet. We currently provide two Installation CDs which are equally suitable to install Gentoo from, as long as you're planning on performing an Internet-based installation using the latest version of the available packages.

If you wish to install Gentoo without a working Internet connection, please use the installation instructions described in the Gentoo 2008.0 Handbooks.

The two Installation CDs that we currently provide are:

• The Gentoo Minimal Installation CD, a small, no-nonsense, bootable CD which sole purpose is to boot the system, prepare the networking and continue with the Gentoo installation.
• The Gentoo Universal Installation CD, a bootable CD with the same abilities as the Minimal Installation CD. Additionally, it contains several stage3 tarballs (optimized for the individual subarchitectures).

To help you decide which Installation CD you need, we have written down the major advantages and disadvantages of each Installation CD.

The Minimal Installation CD is called install-sparc64-minimal-2008.0.iso and takes up only 44 MB of diskspace. You can use this Installation CD to install Gentoo, but always with a working Internet connection only.

The Universal Installation CD is called install-sparc64-universal-2008.0.iso and uses 295 MB. You can use this Installation CD to install Gentoo, and you can even use it to install Gentoo without a working internet connection, just in case you want to bring Gentoo to another PC than the one you are currently installing Gentoo on :)

You might find a Package CD on one of our mirrors. This CD is not an Installation CD but an additional resource that can be exploited during a networkless installation. It contains prebuilt packages (also known as the GRP set) that allow you to easily and quickly install additional applications (such as OpenOffice.org, KDE, GNOME, ...) immediately after the networkless Gentoo installation.

If you intend to use the Packages CD to quickly install additional software, make sure that you use the same subarchitecture as the stage3 tarball you use.

A stage3 tarball is an archive containing a minimal Gentoo environment, suitable to continue the Gentoo installation using the instructions in this manual. Previously, the Gentoo Handbook described the installation using one of three stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the official installation method uses the stage3 tarball. If you are interested in performing a Gentoo installation using a stage1 or stage2 tarball, please read the Gentoo FAQ on How do I Install Gentoo Using a Stage1 or Stage2 Tarball?

You have chosen to use a Gentoo Installation CD. We'll first start by downloading and burning the chosen Installation CD. We previously discussed the several available Installation CDs, but where can you find them?

You can download any of the Installation CDs (and, if you want to, a Packages CD as well) from one of our mirrors. The Installation CDs are located in the installcd directory.

Inside that directory you'll find ISO files. Those are full CD images which you can write on a CD-R.

In case you wonder if your downloaded file is corrupted or not, you can check its MD5 checksum and compare it with the MD5 checksum we provide (such as install-sparc64-minimal-2008.0.iso.DIGESTS). You can check the MD5 checksum with the md5sum tool under Linux/Unix or md5sum for Windows.

Another way to check the validity of the downloaded file is to use GnuPG to verify the cryptographic signature that we provide (the file ending with .asc). Download the signature file and obtain the public key:

$ gpg --keyserver subkeys.pgp.net --recv-keys 17072058

Now verify the signature:

$ gpg --verify <signature file> <downloaded iso>

To burn the downloaded ISO(s), you have to select raw-burning. How you do this is highly program-dependent. We will discuss cdrecord and K3B here; more information can be found in our Gentoo FAQ.

• With cdrecord, you simply type cdrecord dev=/dev/hdc <downloaded iso file> (replace /dev/hdc with your CD-RW drive's device path).
• With K3B, select Tools > Burn CD Image. Then you can locate your ISO file within the 'Image to Burn' area. Finally click Start.

Insert the Gentoo Installation CD in the CD-ROM and boot your system. During startup, press Stop-A to enter OpenBootPROM (OBP). Once you are in the OBP, boot from the CD-ROM:

ok boot cdrom

You will be greeted by the SILO boot manager (on the Installation CD). You can hit Enter for more help if you want. Type in gentoo and press enter to continue booting the system:

boot: gentoo

Once the Installation CD is booted, you will be automatically logged on to the system.

You should have a root ("#") prompt on the current console. You will also find a root prompt on the serial console (ttyS0).

Continue with Extra Hardware Configuration.
