+Yaboot  -- PowerPC GNU/Linux OpenFirmware bootloader
+-------------------------------------------------------------------
+
+Please read the "COPYING" file for licence informations.
+
+-------------------------------------------------------------------
+
+Yaboot is an OpenFirmware bootloader for Open Firmware based
+machines. It is known to work on "NewWorld" class powermacs (iMac and
+all machines released after it), RS/6000, and possibly other OF based
+CHRP machines. "OldWorld" PowerMacs (with the built-in MacOS ROM)
+are not supported.
+
+This README serves as a quick-start introduction to yaboot and its
+installation utilities. For a more complete usage and installation
+guide, see yaboot-howto.html/index.en.html in the same folder where
+this README is located, or else inside the doc folder in this
+directory. For documentation about all the options available, see the
+man pages (bootstrap, yaboot, yaboot.conf, ybin, mkofboot, ofpath,
+yabootconfig).
+
+Mailing lists

+Bootloader Installation Utilities  
+ybin, mkofboot, ofpath, yabootconfig
+Written by Ethan Benson <erbenson(a)alaska.net&gt;
+-------------------------------------------------------------------
+
+ybin (YaBoot INstaller) and mkofboot
+-------------------------------------------------------------------
+
+ybin is a lilo/quik style bootloader installer for PowerPC based
+machines which require a bootstrap partition rather than a traditional
+bootblock (i.e. all `NewWorld' Macintoshes). When ybin is configured
+correctly you can simply type ybin at the command line as root, and
+the bootloader and its configuration file will be installed or updated
+on the bootstrap partition without any further user intervention.
+
+ybin also supports IBM PowerPC hardware which requires a slightly different
+bootstrap partition setup. For these machines, ybin uses dd to write yaboot
+directly to the partition instead of copying it to a filesystem on the
+partition. ybin will add the requisite .note section to yaboot prior to
+installation (IBM CHRP only).
+
+mkofboot is a companion script (actually a symlink to ybin) which
+initializes the bootstrap partition prior to running ybin to install
+the bootloader on it. mkofboot will confirm you want to continue
+before proceeding unless called with the -f or --force switch. This
+is in contrast to ybin, which is non destructive except that it
+overwrites any existing yaboot files (yaboot and yaboot.conf) at the
+root level of the bootstrap filesystem.
+
+mkofboot and ybin both refer to the same configuration file (normally
+yaboot.conf) to determine where the bootstrap files will be placed. 
+
+IMPORTANT: The bootstrap partition should never be mounted anywhere on
+your filesystem, ybin and mkofboot will check if it is and refuse to
+operate on it if it is mounted.  It is not necessary to keep anything
+but the boot loader on the bootstrap partition, yaboot will load the
+kernel from your root partition (which can be an ext2/3, XFS, or
+ReiserFS filesystem). Do not mount the bootstrap partition on top of
+/boot.
+
+ybin can update a bootstrap filesystem either on a block device or in
+an ordinary file (as in an image of a filesystem.) 
+
+NOTE: You must have a secure mktemp program otherwise ybin will be
+vulnerable to race conditions.  Debian's mktemp qualifies I don't know
+about the other distributions, you have been warned. The temp file is
+created in /tmp by default but ybin will respect the $TMPDIR
+environment variable.
+
+
+ofpath
+-------------------------------------------------------------------
+
+The included ofpath utility can usually determine the OpenFirmware
+device path that corresponds with a unix device node in /dev/.  Ybin
+uses this utility to find the path to the bootstrap partition and to
+any defined macos/macosx partitions. ofpath is based on the utility
+`show_of_path.sh' written by Olaf Hering.
+
+
+NOTE: ofpath may not work with all SCSI cards/drivers.
+
+IMPORTANT: ofpath will NOT work on NewWorld Powermacs if the machine
+was booted with BootX.
+
+
+yabootconfig
+-------------------------------------------------------------------
+
+Yabootconfig creates a default configuration file and then runs mkofboot to
+complete the bootloader installation. yabootconfig reads the running
+system's /etc/fstab to determine the kernel location, and detects the
+location of the 800k Apple_Bootstrap partition. It will also find IBM
+CHRP bootstrap partitions (type 0x41 PReP Boot).
+
+
+
+Yaboot.conf Configuration File
+-------------------------------------------------------------------
+
+yaboot.conf configuration file settings are covered in detail in `man
+yaboot.conf'. Avoid the use of spaces in the config file, except in
+comment lines or inside quotes. Here are the essential settings.
+
+
+boot=
+Example:   boot=/dev/hda2
+
+This required setting defines the bootstrap partition device.  It can
+also be a regular file if you are creating a filesystem image for some
+reason. The default config file has this set to ``unconfigured'' which
+will cause ybin to complain about you not reading the docs, it is the
+only option you should need to change for ybin to work. Be sure you
+include the partition number at the end, it should never be something
+like /dev/hda. 
+
+
+install= 
+Example:  install=/usr/lib/yaboot/yaboot or /usr/local/lib/yaboot/yaboot
+
+The full pathname to the yaboot OpenFirmware executable file. The
+default is shown above. This file will be copied to the root level of
+the bootstrap partition. Note: If you are installing an alternative
+bootloader, its filename will be changed to yaboot when it is copied
+(to match what the first stage bootloader expects to be loading).
+
+
+partition=
+Example:   partition=3
+
+The partition number on which the kernel image is located. By default,
+this partition is assumed to be on the same device from which yaboot
+was loaded. If needed, device= can be used to explicitly specify the 
+device.
+
+
+image=
+Examples:  image=/vmlinux  or  image=/boot/vmlinux-2.2.19-pmac
+
+The path to the image from the root level of the partition (remember
+that yaboot is unaware of mountpoints).  Don't forget to include the
+leading slash when specifying the image path (image=vmlinux will
+probably fail).
+
+
+root=
+Example:   root=/dev/hda3
+
+The Linux device name for the root partition. This parameter is
+passed to the kernel when it starts up to let it know where its root
+filesystem is located. Refer to the yaboot.conf man page for details
+on kernel image options such as append=, initrd=, and initrd-size=.
+
+
+magicboot= (same as -m or --magicboot)
+Example:   /usr/local/lib/yaboot/ofboot 
+
+Identifies the first stage loader. The example shown is the default. The
+ofboot script it refers to is included with and configured automatically by
+ybin from options in /etc/yaboot.conf. The magicboot= can be the full
+pathname to any OF CHRP script file. Since some newer OpenFirmware
+implementations appear to require a CHRP script, the magicboot= setting is
+highly recommended. If you don't include magicboot=, then yaboot itself will
+be the active bootfile.  magicboot= cannot be used on IBM CHRP.
+
+
+Boot Menu Options
+-------------------------------------------------------------------
+
+The following options work only if you have specified the magicboot= option.
+Each option specifies an OpenFirmware or unix device path to another
+operating system's boot partition.  When you define one of these options you
+will be presented with a simple menu at bootup allowing you to hit `l' to
+boot GNU/Linux or another letter to boot the other OS (see below). These
+letters are typed without a shift key (the boot menu is case sensitive).
+When set to a unix device node such as /dev/hda11 then ybin will use the
+ofpath utility to determine the OpenFirmware device path.
+
+  Option       Letter  Operating System Type
+  ---------    ------  ---------------------------------------------
+  bsd=           b     NetBSD or OpenBSD root partition (you must 
+                          have the BSD ofwboot bootloader 
+                          installed at /usr/local/lib/yaboot/ofwboot)
+
+  macos=         m     MacOS 8.* or 9.* bootable partition
+
+  macosx=        x     MacOS X boot partition (also see brokenosx)
+
+  darwin=        d     Darwin boot partition
+
+  enablecdboot   c     Boot from the CDROM drive
+
+  enablenetboot  n     Boot from the network
+
+  enableofboot   o     Display an OpenFirmware prompt
+
+  defaultos=           The default OS to load (linux, bsd, macos, 
+                          darwin or macosx.
+
+brokenosx
+
+This option causes the menu entry for MacOSX to execute
+\System\Library\CoreServices\BootX from the macosx=device instead of
+the usual \\:tbxi.  This is necessary if OSX is installed onto an HFS+
+filesystem instead of UFS. When OSX is installed on an HFS+ filesystem
+MacOS will mount and debless the OSX partition.  Add this option if
+the OSX menu entry breaks after booting MacOS.  You should not use
+this option if OSX is installed on a UFS filesystem, for UFS installs
+you specify the OSX bootstrap partition which is protected against
+MacOS.
+
+delay= 
+Example:  delay=5
+
+The time in seconds that the first stage ofboot loader will wait for
+you to choose a letter before booting the default OS defined in
+defaultos=.  If not set, the value of timeout= (converted to seconds)
+will be used.
+
+
+Colors
+-------------------------------------------------------------------
+
+fgcolor=string
+
+Specifies the foreground (text) color used by yaboot and the
+multiboot menu.  Available colors are: black, blue, light-blue, green,
+light-green, cyan, light-cyan, red, light-red, purple, light- purple,
+brown, light-gray, dark-gray, yellow, and white.  The default is
+white.
+
+bgcolor=string
+
+Specifies the background color used by yaboot and the multiboot
+menu.  Available colors are the same as fgcolor. The default is
+black.
