&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 > boot cd:,\install\yaboot

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.

replacing <replaceable>x</replaceable> with the partition number of
the HFS partition where 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> .
