  <sect2 arch="m68k"><title>Choosing an Installation Method</title>

<para>

Some &arch-title; subarchs have the option of booting using either a
2.4.x or 2.2.x linux kernel. When such a choice exists, try the 2.4.x
linux kernel. The installer should also require less memory when using
a 2.4.x linux kernel as 2.2.x support requires a fixed-sized ramdisk
and 2.4.x uses tmpfs.

</para><para>

If you are using a 2.2.x linux kernel, then you need to use the &ramdisksize;
kernel parameter.

</para><para>

Make sure <userinput>root=/dev/ram</userinput> is one of your kernel
parameters.

</para><para>

If you're having trouble, check
<ulink url="&url-m68k-cts-faq;">cts's &arch-title; debian-installer FAQ</ulink>.

The installer for BVME6000 may be started from a cdrom

<emphasis>In other words the cdrom is not bootable.</emphasis>
Macs do not have a working 2.4.x kernel.

</para><para>

If your hardware uses a 53c9x-based scsi bus, then you may need to
include the kernel parameter <userinput>mac53c9x=1,0</userinput>.
Hardware with two such scsi buses, such as the Quadra 950, will need
<userinput>mac53c9x=2,0</userinput> instead. Alternatively, the
parameter can be specified as <userinput>mac53c9x=-1,0</userinput>
which will leave autodetection on, but which will disable SCSI
disconnects. Note that specifying this parameter is only necessary
if you have more than one hard disk; otherwise, the system will run
faster if you do not specify it.

  <sect2 arch="m68k" id="m68k-boot-hd"><title>Booting from a Hard Disk</title>

&boot-installer-intro-hd.xml;

<para>

At least six different ramdisks may be used to boot from the hard
drive, three different types each with and without support for a
2.2.x linux kernel (see
<ulink url="&disturl;/main/installer-&architecture;/current/images/MANIFEST">MANIFEST</ulink>
for details).

</para><para>

The three different types of ramdisks are <filename>cdrom</filename>,
<filename>hd-media</filename>, and <filename>nativehd</filename>. These
ramdisks differ only in their source for installation packages.
The <filename>cdrom</filename> ramdisk uses a cdrom to get
debian-installer packages. The <filename>hd-media</filename> ramdisk
uses an iso image file of a cdrom currently residing on a hard disk.
Finally, the <filename>nativehd</filename> ramdisk uses the net to
install packages.

    <sect3 id="m68k-boothd-mac"><title>Booting from MacOS</title>
<para>

You must retain the original Mac system and
boot from it. It is <emphasis>essential</emphasis> that, when booting
MacOS in preparation for booting the Penguin linux loader, you
hold the <keycap>shift</keycap> key down to prevent extensions from
loading. If you don't use MacOS except for loading linux, you can
accomplish the same thing by removing all extensions and control
panels from the Mac's System Folder. Otherwise extensions may be left
running and cause random problems with the running linux kernel.

</para><para>

Macs require the <command>Penguin</command> bootloader, which can be
downloaded from <ulink url="&url-m68k-mac;">the Linux/mac68k
sourceforge.net project</ulink>. If you do not have the tools to handle
a <command>Stuffit</command> archive, you can put it on a
MacOS-formatted floppy using a second GNU/Linux machine of any
architecture and the <command>hmount</command>,
<command>hcopy</command>, and <command>humount</command> tools from the
<classname>hfsutils</classname> suite.

At the MacOS desktop, start the Linux installation process by
double-clicking on the <guiicon>Penguin Prefs</guiicon> icon in
the <filename>Penguin</filename> directory. The
<command>Penguin</command> booter will start up. Go to the
<guimenuitem>Settings</guimenuitem> item in the

<guilabel>Kernel</guilabel> tab.  Select the kernel
(<filename>vmlinuz</filename>) and ramdisk
(<filename>initrd.gz</filename>) images in the
<filename>install</filename> directory by clicking on the corresponding
buttons in the upper right corner, and navigating the file select
dialogs to locate the files.

To set the boot parameters in Penguin, choose <guimenu>File</guimenu> -&gt;
