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.

The Minimal Installation CD is called and takes up only 47 MB of diskspace. You must use this Installation CD to install Gentoo, and you need a working Internet connection.

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 .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.

When your Alpha is powered on, the first thing that gets started is the firmware. It is loosely synonymous with the BIOS software on PC systems. There are two types of firmware on Alpha systems: SRM (Systems Reference Manual) and ARC (Advanced Risc Console).

SRM is based on the Alpha Console Subsystem specification, which provides an operating environment for OpenVMS, Tru64 UNIX, and Linux operating systems. ARC is based on the Advanced RISC Computing (ARC) specification, which provides an operating environment for Windows NT. You can find a detailed guide on using SRM over at the Alpha Linux website.

If your Alpha system supports both SRM and ARCs (ARC, AlphaBIOS, ARCSBIOS) you should follow these instructions for switching to SRM. If your system already uses SRM, you are all set. If your system can only use ARCs (Ruffian, nautilus, xl, etc.) you will need to choose MILO later on when we are talking about bootloaders.

Now to boot an Alpha Installation CD, put the CD-ROM in the tray and reboot the system. You can use SRM to boot the Installation CD. If you cannot do that, you will have to use MILO. If you don't have MILO installed already, use one of the precompiled MILO images available on taviso's homepage.

dkb0.0.1.4.0        DKB0       TOSHIBA CDROM

(Substitute dkb0 with your CD-ROM drive device)
>>> boot dkb0 -flags 0
(If you need serial console support)
>>> boot dkb0 -flags 2

(Substitute sdb with your CD-ROM drive device)
MILO> boot sdb:/boot/gentoo_2.6 initrd=/boot/gentoo_2_6.igz root=/dev/ram0 init=/linuxrc looptype=zisofs loop=/zisofs cdroot
(If you need serial console support)
MILO> boot sdb:/boot/gentoo_2.6 initrd=/boot/gentoo_2_6.igz root=/dev/ram0 init=/linuxrc looptype=zisofs loop=/zisofs console=ttyS0 cdroot

You should have a root ("#") prompt on the current console and can also switch to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you started on by pressing Alt-F1.

Now continue with Extra Hardware Configuration.
