Now that your kernel is configured and compiled and the necessary system
|
| 18 |
configuration files are filled in correctly, it is time to install a
|
| 19 |
program that will fire up your kernel when you start the system. Such a
|
| 20 |
program is called a <e>bootloader</e>.
|
| 21 |
</p>
|
| 22 |
|

<p>
|

On Linux/PPC64 we have only yaBoot as a bootloader untill grub2 is
|
| 25 |
finished.

You have to use yaboot-static instead of yaboot, because yaboot won't
|
| 39 |
compile on PPC64.
|
| 40 |
</impo>
|
| 41 |
|
| 42 |
<p>
|
| 43 |
There are two ways to configure yaBoot for your system. You can use the
|
| 44 |
new and improved <c>yabootconfig</c> included with
|
| 45 |
<path>yaboot-1.3.8-r1</path> and later to automatically setup yaboot. If
|
| 46 |
for some reason you do not want to run <c>yabootconfig</c> to
|
| 47 |
automatically setup <path>/etc/yaboot.conf</path> or you are installing Gentoo
|
| 48 |
on a G5 (on which <c>yabootconfig</c> does not always work), you can just edit
|
| 49 |
the sample file already installed on your system.
|
| 50 |
</p>
|
| 51 |
|
| 52 |
<impo>
|
| 53 |
yabootconfig/ybin won't work on IBM. You have to install yaboot another way:

|

<c>yabootconfig</c> will auto-detect the partitions on your machine and will
|
| 72 |
setup dual and triple boot combinations with Linux, Mac OS, and Mac OS
|
| 73 |
X.
|
| 74 |
</p>
|
| 75 |
|
| 76 |
<p>
|
| 77 |
To use <c>yabootconfig</c>, your drive must have a bootstrap partition, and
|
| 78 |
<path>/etc/fstab</path> must be configured with your Linux partitions. Both of
|
| 79 |
these should have been done already in the steps above. To start, ensure that
|
| 80 |
you have the latest version of yaboot installed by running <c>emerge --update
|
| 81 |
yaboot-static</c>. This is necessary as the latest version will be available via
|
| 82 |
Portage, but it may not have made it into the stage files.
|
| 83 |
</p>
|
| 84 |
|
| 85 |
<pre caption = "Installing yaboot-static">
|
| 86 |
# <i>emerge --update yaboot-static</i>
|
| 87 |
</pre>
|
| 88 |
|
| 89 |
<p>
|
| 90 |
Now run <c>yabootconfig</c>. The program will run and it will confirm
|
| 91 |
the location of the bootstrap partition. Type <c>Y</c> if it is correct. If
|
| 92 |
not, double check <path>/etc/fstab</path>. yabootconfig will then scan your
|
| 93 |
system setup, create <path>/etc/yaboot.conf</path> and run <c>mkofboot</c> for
|
| 94 |
you. <c>mkofboot</c> is used to format the bootstrap partition, and install
|
| 95 |
the yaboot configuration file into it.
|
| 96 |
</p>
|
| 97 |
|
| 98 |
<p>
|
| 99 |
You might want to verify the contents of <path>/etc/yaboot.conf</path>. If
|
| 100 |
you make changes to <path>/etc/yaboot.conf</path> (like setting the
|
| 101 |
default/boot OS), make sure to rerun <c>ybin -v</c> to apply changes to the
|
| 102 |
bootstrap partition.

Once <path>yaboot.conf</path> is set up the way you want it, you run
|
| 180 |
<c>mkofboot -v</c> to install the settings in the bootstrap partition.
|
| 181 |
<e>Don't forget this!</e> If all goes well, and you have the same
|
| 182 |
options as the sample above, your next reboot will give you a simple,
|
| 183 |
five-entry boot menu. If you update your yaboot config later on, you'll
|
| 184 |
just need to run <c>ybin -v</c> to update the bootstrap partition -
|
| 185 |
<c>mkofboot</c> is for initial setup only.

On IBM hardware you cannot run yabootconfig or ybin. You have to proceed
|
| 204 |
the folowing steps:
|
| 205 |
</p>
|
| 206 |
|
| 207 |
<ul>
|
| 208 |
<li>Install yaboot-static</li>
|
| 209 |
<li>Run 'dd if=/usr/lib/yaboot/yaboot.chrp of=/dev/sdXX' (fill in XX
|
| 210 |
with your disk and partition for the RPeP partition; this was in our
|
| 211 |
example /dev/sda1)</li>
|
| 212 |
<li>Next construct your own yaboot.conf file and place into /etc.
|
| 213 |
(Take a look at the config above or look into the man page of
|
| 214 |
yaboot.conf)</li>
|
| 215 |
<li>Assuming your boot device in OF is pointing to the harddrive you
|
| 216 |
prep boot partition is on then it'll just work, otherwise at IPL time,
|
| 217 |
go into the multiboot menu and set the boot device to the one with
|
| 218 |
your prep boot partition.</li>
|
| 219 |
<li>That's it!</li>
|
| 220 |
</ul>

Exit the chrooted environment and unmount all mounted partitions. Then type in
|
| 231 |
that one magical command you have been waiting for: <c>reboot</c>.
|
| 232 |
</p>
|
| 233 |
|
| 234 |
<pre caption="Exiting the chroot, unmounting all partitions and rebooting">

|

|
| 240 |
<p>
|

Of course, don't forget to remove the bootable CD, otherwise the CD will be
|
| 242 |
booted again instead of your new Gentoo system.
|
| 243 |
</p>
|
| 244 |
|
| 245 |
<p>
|
| 246 |
Once rebooted in your Gentoo installation, finish up with <uri
