21     Now that your kernel is configured and compiled and the necessary system
22     configuration files are filled in correctly, it is time to install a
23     program that will fire up your kernel when you start the system. Such a
24     program is called a <e>bootloader</e>.
25     </p>
26    
27     <p>
28 jkt 1.16 On Linux/PPC64 we have only yaBoot as a bootloader until grub2 is
29 swift 1.1 finished.

41     <impo>
42     You have to use yaboot-static instead of yaboot, because yaboot won't
43     compile on PPC64.
44     </impo>
45    
46     <p>
47     There are two ways to configure yaBoot for your system. You can use the
48     new and improved <c>yabootconfig</c> included with
49 swift 1.4 <path>yaboot-1.3.8-r1</path> and later to automatically set up yaboot. If
50 swift 1.1 for some reason you do not want to run <c>yabootconfig</c> to
51 swift 1.4 automatically set up <path>/etc/yaboot.conf</path> or you are installing Gentoo
52 swift 1.1 on a G5 (on which <c>yabootconfig</c> does not always work), you can just edit
53     the sample file already installed on your system.
54     </p>
55    
56     <impo>
57     yabootconfig/ybin won't work on IBM. You have to install yaboot another way:
58 swift 1.14 <uri link="#yaboot-ibm">Using yaboot on IBM hardware</uri>
59 swift 1.1 </impo>
60    
61 swift 1.13 <note>
62     If your root filesystem uses the JFS filesystem, be sure to add <c>ro</c> as a
63     kernel parameter. JFS must be able to replay its log in read-only mode before it
64     gets mounted read-write.

79    
80     <p>
81     <c>yabootconfig</c> will auto-detect the partitions on your machine and will
82 swift 1.4 set up dual and triple boot combinations with Linux, Mac OS, and Mac OS
83 swift 1.1 X.
84     </p>
85    
86     <p>
87     To use <c>yabootconfig</c>, your drive must have a bootstrap partition, and
88     <path>/etc/fstab</path> must be configured with your Linux partitions. Both of
89     these should have been done already in the steps above. To start, ensure that
90     you have the latest version of yaboot installed by running <c>emerge --update
91     yaboot-static</c>. This is necessary as the latest version will be available via
92     Portage, but it may not have made it into the stage files.
93     </p>
94    
95     <pre caption = "Installing yaboot-static">
96     # <i>emerge --update yaboot-static</i>
97     </pre>
98    
99     <p>
100     Now run <c>yabootconfig</c>. The program will run and it will confirm
101     the location of the bootstrap partition. Type <c>Y</c> if it is correct. If
102     not, double check <path>/etc/fstab</path>. yabootconfig will then scan your
103     system setup, create <path>/etc/yaboot.conf</path> and run <c>mkofboot</c> for
104     you. <c>mkofboot</c> is used to format the bootstrap partition, and install
105     the yaboot configuration file into it.
106     </p>
107    
108     <p>
109     You might want to verify the contents of <path>/etc/yaboot.conf</path>. If
110     you make changes to <path>/etc/yaboot.conf</path> (like setting the
111     default/boot OS), make sure to rerun <c>ybin -v</c> to apply changes to the
112     bootstrap partition.
113     </p>
114    
115     <p>
116     Now continue with <uri link="#reboot">Rebooting your System</uri>.

185     Once <path>yaboot.conf</path> is set up the way you want it, you run

192     If all goes well, and you have the same
193 swift 1.1 options as the sample above, your next reboot will give you a simple,
194     five-entry boot menu. If you update your yaboot config later on, you'll
195     just need to run <c>ybin -v</c> to update the bootstrap partition -
196     <c>mkofboot</c> is for initial setup only.

212    
213     <p>
214 swift 1.14 On IBM hardware you cannot run yabootconfig or ybin. You must proceed with the
215     folowing steps:
216 swift 1.1 </p>
217    
218     <ul>
219     <li>Install yaboot-static</li>
220     <li>Run 'dd if=/usr/lib/yaboot/yaboot.chrp of=/dev/sdXX' (fill in XX
221 swift 1.14 with your disk and partition for the PReP partition; this was in our
222 swift 1.1 example /dev/sda1)</li>
223     <li>Next construct your own yaboot.conf file and place into /etc.
224 swift 1.11 (Take a look at the config above, look into the man page of
225     yaboot.conf or look at the below yaboot.conf example)</li>
226 swift 1.1 <li>Assuming your boot device in OF is pointing to the harddrive you
227     prep boot partition is on then it'll just work, otherwise at IPL time,
228     go into the multiboot menu and set the boot device to the one with
229     your prep boot partition.</li>
230     <li>That's it!</li>
231     </ul>
232    
233 swift 1.14 <pre caption = "yaboot.conf for IBM hardware">
234 swift 1.11 device=disk:
235     partition=2
236     root=/dev/sda2

246 swift 1.14 <p>
247     For POWER4, POWER5, and blade-based hardware where the PReP disk partition
248     and the disk partition that contains your kernel are on the same physical disk,
249     you can use a simplified yaboot.conf. The following should be sufficient:
250     </p>
251    
252     <pre caption="yaboot.conf for PReP hardware">
253     default = linux

270     10+0 records out
271     </pre>
272

274     A match signifies that yaboot was installed correctly.

285     Exit the chrooted environment and unmount all mounted partitions. Then type in
