Before we start, we first list what hardware requirements you need to
|
| 22 |
successfully install Gentoo on your box.

Pretty much every IA64 should be able to boot Gentoo. At the moment we only
|
| 33 |
have LiveCDs, so your machine must have a CDROM drive installed.

The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
|
| 48 |
self-sustained Gentoo environment. They allow you to boot Linux from the CD.
|
| 49 |
During the boot process your hardware is detected and the appropriate drivers
|
| 50 |
are loaded. They are maintained by Gentoo developers.
|
| 51 |
</p>
|
| 52 |
|
| 53 |
<p>
|
| 54 |
All Installation CDs allow you to boot, set up networking, initialize your
|
| 55 |
partitions and start installing Gentoo from the Internet.
|
| 56 |
</p>
|
| 57 |
<!--

If you wish to install Gentoo without a working Internet connection, or would
|
| 60 |
like to use one of the provided installers, please use the installation
|
| 61 |
instructions described in the <uri link="2008.0/">Gentoo 2008.0

<title>The Stage3 Tarball</title>
|

<body>
|
| 113 |
|
| 114 |
<p>
|
| 115 |
A stage3 tarball is an archive containing a minimal Gentoo environment,
|
| 116 |
suitable to continue the Gentoo installation using the instructions in this
|
| 117 |
manual. Previously, the Gentoo Handbook described the installation using one of
|
| 118 |
three stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
|
| 119 |
official installation method uses the stage3 tarball. If you are interested in
|
| 120 |
performing a Gentoo installation using a stage1 or stage2 tarball, please read
|
| 121 |
the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo
|
| 122 |
Using a Stage1 or Stage2 Tarball?</uri>
|
| 123 |
</p>
|
| 124 |
|
| 125 |
<p>
|
| 126 |
Stage3 tarballs can be downloaded from <path><keyval
|
| 127 |
id="release-dir"/>current-stage3/</path> on any of the <uri
|

<title>Download, Burn and Boot a Gentoo Installation CD</title>

<title>Downloading and Burning the Installation CDs</title>
|
| 139 |
<body>
|
| 140 |
|
| 141 |
<p>
|
| 142 |
You have chosen to use a Gentoo Installation CD. We'll first start by
|
| 143 |
downloading and burning the chosen Installation CD. We previously discussed
|
| 144 |
the several available Installation CDs, but where can you find them?
|
| 145 |
</p>
|
| 146 |
|
| 147 |
<p>
|
| 148 |
You can download any of the Installation CDs from one of our <uri
|
| 149 |
link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
|
| 150 |
the <path><keyval id="release-dir"/>current-iso/</path> directory.
|
| 151 |
</p>
|
| 152 |
|
| 153 |
<p>
|
| 154 |
Inside that directory you'll find ISO files. Those are full CD images which you
|
| 155 |
can write on a CD-R.
|
| 156 |
</p>
|
| 157 |
|
| 158 |
<p>
|
| 159 |
In case you wonder if your downloaded file is corrupted or not, you can check
|
| 160 |
its MD5 checksum and compare it with the MD5 checksum we provide (such as
|
| 161 |
<path><keyval id="min-cd-name"/>.DIGESTS</path>). You can check the MD5
|
| 162 |
checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
|
| 163 |
link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
|
| 164 |
</p>
|
| 165 |
|
| 166 |
<p>
|
| 167 |
Another way to check the validity of the downloaded file is to use GnuPG to
|
| 168 |
verify the cryptographic signature that we provide (the file ending with
|
| 169 |
<path>.asc</path>). Download the signature file and obtain the public keys whose
|
| 170 |
key ids can be found on the <uri link="/proj/en/releng/index.xml">release
|
| 171 |
engineering project site</uri>.
|
| 172 |
</p>
|
| 173 |
|
| 174 |
<pre caption="Obtaining the public key">
|
| 175 |
<comment>(... Substitute the key ids with those mentioned on the release engineering site ...)</comment>
|
| 176 |
$ <i>gpg --keyserver subkeys.pgp.net --recv-keys 96D8BF6D 2D182910 17072058</i>
|
| 177 |
</pre>
|
| 178 |
|
| 179 |
<p>
|
| 180 |
Now verify the signature:
|
| 181 |
</p>
|
| 182 |
|
| 183 |
<pre caption="Verify the files">
|
| 184 |
<comment>(Verify the cryptographic signature)</comment>
|
| 185 |
$ <i>gpg --verify <downloaded iso.DIGESTS.asc></i>
|
| 186 |
<comment>(Verify the checksum)</comment>
|
| 187 |
$ <i>sha1sum -c <downloaded iso.DIGESTS.asc></i>
|
| 188 |
</pre>
|
| 189 |
|
| 190 |
<p>
|
| 191 |
To burn the downloaded ISO(s), you have to select raw-burning. How you
|
| 192 |
do this is highly program-dependent. We will discuss <c>cdrecord</c> and
|
| 193 |
<c>K3B</c> here; more information can be found in our <uri
|
| 194 |
link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
|
| 195 |
</p>
|
| 196 |
|
| 197 |
<ul>
|
| 198 |
<li>
|
| 199 |
With cdrecord, you simply type <c>cdrecord dev=/dev/hdc <downloaded iso
|
| 200 |
file></c> (replace <path>/dev/hdc</path> with your CD-RW drive's
|
| 201 |
device path).
|
| 202 |
</li>
|
| 203 |
<li>
|
| 204 |
With K3B, select <c>Tools</c> > <c>Burn CD Image</c>. Then you can locate
|
| 205 |
your ISO file within the 'Image to Burn' area. Finally click <c>Start</c>.
|
| 206 |

|
| 207 |

<title>Booting the Installation CD</title>
|
| 213 |
<body>
|
| 214 |
|
| 215 |
<p>
|
| 216 |
Once you have burnt your installation CD, it is time to boot it.
|
| 217 |
Remove all CDs from your CD drives, and insert the Gentoo
|
| 218 |
InstallCD. Reboot your system and wait for the EFI firmware to load on
|
| 219 |
the console. The exact option to select will differ depending on your
|
| 220 |
hardware.
|
| 221 |
</p>
|
| 222 |
|
| 223 |
<p>
|
| 224 |
Most implementations usually present an option directly on the first
|
| 225 |
menu (the EFI Boot Manager). The exact wording would differ but would
|
| 226 |
usually be something like "CD Boot", "Removable Media
|
| 227 |
Boot" or "Internal Bootable DVD". Select this option.
|
| 228 |
</p>
|
| 229 |
|
| 230 |
<p>
|
| 231 |
If your EFI implementation does not present such an option, you can
|
| 232 |
boot the CD using the EFI Shell. All implementations will present an
|
| 233 |
option to enter the shell on the Boot Manager menu. Select this
|
| 234 |
option. The EFI Shell will display a list of usable block devices
|
| 235 |
(<c>blk<b>n</b>:</c>) and also a list of filesystems the EFI Shell
|
| 236 |
can actually access (<c>fs<b>n</b>:</c>).
|
| 237 |
</p>
|
| 238 |
|
| 239 |
<p>
|
| 240 |
In most cases the option you want will be the <c>fs0:</c> choice;
|
| 241 |
regardless, (provided the CD drive recognizes the CD), you should
|
| 242 |
see one <c>fs<b>n</b></c> entry for your CD drive (the CD drive's
|
| 243 |
EFI device path will contain <c>CDROM</c> in the wording). Enter
|
| 244 |
<c>fs<b>n</b>:</c>, replacing <b>n</b> as required and including
|
| 245 |
the colon, followed by the Enter key. Next just type <c>elilo</c>
|
| 246 |
followed by the Enter key.
|
| 247 |
</p>
|
| 248 |
|
| 249 |
<p>
|
| 250 |
You will now be greeted by the ELILO boot message and asked to
|
| 251 |
enter a kernel to boot as well as any additional options to pass
|
| 252 |
to the kernel command line. In most cases just hit the Enter key
|
| 253 |
or wait five seconds. Only one kernel is supplied on the IA64
|
| 254 |
InstallCD, the <c>gentoo</c> kernel.
|
| 255 |
</p>
|
| 256 |
|
| 257 |
<p>
|
| 258 |
Several kernel aliases are provided which add extra options to
|
| 259 |
the kernel command line, which you may have to use instead of
|
| 260 |
the default <c>gentoo</c> option depending on your hardware:
|
| 261 |
</p>
|
| 262 |
|
| 263 |
<p>
|
| 264 |
The <c>gentoo-serial</c> option forces a serial console on the first
|
| 265 |
serial port (ttyS0) at 9600bps. This may be required on some older EFI
|
| 266 |
implementations where the kernel can't detect what console to use. You
|
| 267 |
should try this option if booting the default <c>gentoo</c> kernel
|
| 268 |
produces no output and if you are using a serial console. If you use a
|
| 269 |
serial console which is not connected to the first serial port you
|
| 270 |
must manually select the console by typing <c>gentoo
|
| 271 |
console=ttyS#,9600</c> where <c>#</c> is the number of the serial
|
| 272 |
port.
|
| 273 |
</p>
|
| 274 |
|
| 275 |
<p>
|
| 276 |
The <c>gentoo-ilo</c> option forces a serial console on the <c>ttyS3</c> serial
|
| 277 |
port at 9600bps. This should be used if you're installing using the HP iLO
|
| 278 |
remote console feature.
|
| 279 |
</p>
|
| 280 |
|
| 281 |
<p>
|
| 282 |
The <c>gentoo-sgi</c> option forces a serial console on the <c>ttySG0</c>
|
| 283 |
serial port at 115200bps. This should only be needed on SGI hardware, and
|
| 284 |
if the console is properly selected in the default EFI settings, or if you
|
| 285 |
are using a video console this option should not be required.
|
| 286 |
</p>
|
| 287 |
|
| 288 |
</body>
|
| 289 |
<body>
|
| 290 |
|
| 291 |
<p>
|
| 292 |
You can also provide kernel options. They represent optional settings
|
| 293 |
you can (de)activate at will.
|
| 294 |
</p>
|
| 295 |
|

|

<body>
|
| 303 |
|
| 304 |
<note>
|
| 305 |
The CD will check for "no*" options before "do*" options, so that you can
|
| 306 |
override any option in the exact order you specify.
|
| 307 |
</note>
|
| 308 |
|
| 309 |
<p>
|
| 310 |
You will then be greeted with a boot screen. If you are installing Gentoo on a
|
| 311 |
system with a non-US keyboard, make sure you select the layout at the prompt. If
|
| 312 |
no selection is made in 10 seconds the default (US keyboard) will be accepted
|
| 313 |
and the boot process will continue. Once the boot process completes, you will be
|
| 314 |
automatically logged in to the "Live" Gentoo Linux as "root", the super user.
|
| 315 |
You should have a root ("#") prompt on the current console. If you are using a
|
| 316 |
video console and have a keyboard connected you can also switch to other
|
| 317 |
consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you started
|
| 318 |
on by pressing Alt-F1.
