&boot-installer-intro-cd.xml;

<para>

Currently, the only &arch-title; subarchitectures that support CD-ROM
booting are PReP and New World PowerMacs. On PowerMacs, hold the
<keycap>c</keycap> key, or else the combination of
<keycap>Command</keycap>, <keycap>Option</keycap>,
<keycap>Shift</keycap>, and <keycap>Delete</keycap>
keys together while booting to boot from the CD-ROM.

</para><para>

OldWorld PowerMacs will not boot a Debian CD, because OldWorld
computers relied on a Mac OS ROM CD boot driver to be present on the CD,
and a free-software version of this driver is not available. All
OldWorld systems have floppy drives, so use the floppy drive to launch
the installer, and then point the installer to the CD for the needed
files.

</para><para>

If your system doesn't boot directly from CD-ROM, you can still use
the CD-ROM to install the system. On NewWorlds, you can also use an
OpenFirmware command to boot from the CD-ROM manually. Follow the
instructions in <xref linkend="boot-newworld"/> for booting from
the hard disk, except use the path to <command>yaboot</command> on the
CD at the OF prompt, such as

<informalexample><screen>
0 &gt; boot cd:,\install\yaboot
</screen></informalexample>

<para>

If you set up BootX in <xref linkend="files-oldworld"/>, you can
use it to boot into the installation system. Double click the
<guiicon>BootX</guiicon> application icon. Click on the
<guibutton>Options</guibutton> button and select <guilabel>Use
Specified RAM Disk</guilabel>. This will give you the
chance to select the <filename>ramdisk.image.gz</filename> file. You
may need to select the <guilabel>No Video Driver</guilabel> checkbox,
depending on your hardware. Then click the
<guibutton>Linux</guibutton> button to shut down MacOS and launch the
installer.

You will have already placed the <filename>vmlinux</filename>,
<filename>initrd.gz</filename>, <filename>yaboot</filename>, and
<filename>yaboot.conf</filename> files at the root level of your HFS
partition in <xref linkend="files-newworld"/>.
Restart the computer, and immediately (during the chime) hold down the
<keycap>Option</keycap>, <keycap>Command (cloverleaf/Apple)</keycap>,
<keycap>o</keycap>, and <keycap>f</keycap> keys all together. After
a few seconds you will be presented with the Open Firmware prompt.
At the prompt, type

<informalexample><screen>
0 &gt; boot hd:<replaceable>x</replaceable>,yaboot
</screen></informalexample>

replacing <replaceable>x</replaceable> with the partition number of
the HFS partition where the
kernel and yaboot files were placed, followed by a &enterkey;. On some
machines, you may need to use <userinput>ide0:</userinput> instead of
<userinput>hd:</userinput>. In a few more seconds you will see a
yaboot prompt

<informalexample><screen>
boot:
</screen></informalexample>

At yaboot's <prompt>boot:</prompt> prompt, type either
<userinput>install</userinput> or <userinput>install video=ofonly</userinput>
followed by a &enterkey;.  The
<userinput>video=ofonly</userinput> argument is for maximum
compatibility; you can try it if <userinput>install</userinput>

  <title>Booting from USB memory stick</title>
<para>

Currently, NewWorld PowerMac systems are known to support USB booting.

</para>

<para>

Make sure you have prepared everything from <xref
linkend="boot-usb-files"/>. To boot a Macintosh system from a USB stick,
you will need to use the Open Firmware prompt, since Open Firmware does
not search USB storage devices by default.
<!-- TODO: although it could be made to; watch this space -->
To get to the prompt, hold down
<keycombo><keycap>Command</keycap> <keycap>Option</keycap>
<keycap>o</keycap> <keycap>f</keycap></keycombo> all together while
booting (see <xref linkend="invoking-openfirmware"/>).

</para><para>

You will need to work out where the USB storage device appears in the
device tree, since at the moment <command>ofpath</command> cannot work
that out automatically. Type <userinput>dev / ls</userinput> and
<userinput>devalias</userinput> at the Open Firmware prompt to get a
list of all known devices and device aliases. On the author's system
with various types of USB stick, paths such as
<filename>usb0/disk</filename>, <filename>usb0/hub/disk</filename>,
<filename>/pci@f2000000/usb@1b,1/disk@1</filename>, and
<filename>/pci@f2000000/usb@1b,1/hub@1/disk@1</filename> work.

</para><para>

Having worked out the device path, use a command like this to boot the
installer:

<informalexample><screen>
boot <replaceable>usb0/disk</replaceable>:<replaceable>2</replaceable>,\\:tbxi
</screen></informalexample>

The <replaceable>2</replaceable> matches the Apple_HFS or
Apple_Bootstrap partition onto which you copied the boot image earlier,
and the <userinput>,\\:tbxi</userinput> part instructs Open Firmware to
boot from the file with an HFS file type of "tbxi" (i.e.
<command>yaboot</command>) in the directory previously blessed with
<command>hattrib -b</command>.

</para><para>

The system should now boot up, and you should be presented with the
<prompt>boot:</prompt> prompt. Here you can enter optional boot
arguments, or just hit &enterkey;.

</para><warning><para>

This boot method is new, and may be difficult to get to work on some
NewWorld systems. If you have problems, please file an installation
report, as explained in <xref linkend="submit-bug"/>.

On machines with Open Firmware, such as NewWorld Power Macs, enter the

  <sect2 arch="powerpc"><title>PowerPC Boot Parameters</title>
<para>

Many older Apple monitors used a 640x480 67Hz mode. If your video
appears skewed on an older Apple monitor, try appending the boot
argument <userinput>video=atyfb:vmode:6</userinput> , which will
select that mode for most Mach64 and Rage video hardware. For Rage 128
hardware, this changes to
<userinput>video=aty128fb:vmode:6</userinput> .
