These don't entirely work.
These instructions won't work, as the Ubuntu kernel does not have the necessary bits compiled in -- SCSI, fw support, and sbp-2. See http://macubuntu.blogspot.com/ for step-by-step instructions on how to get this to work.
===设备无法正常工作＝＝＝
因为Ubuntu的内核没有对SCSI、火线借口和SBP－2（Serial Bus Protocol）设备的支持和编译，所以无法正常使用。请根据http://macubuntu.blogspot.com/ 上面的指示来使其正常工作。

Here you have a link to a howto to boot from a harddisk. 这里有一个链接是教你如何从硬盘启动的。
I'm not sure if the link will be valid too much time so here you have the important bits: 我不敢肯定该链接的有效期是多久，所以你要注意下面的部分：
3. i. Next is to locate the firmware path of the FireWire drive:
# find /proc/device-tree/ -name disk@\* | grep -i firewire /proc/device-tree/pci@f4y000000/FireWire@e/node@0001d200e00260c6/sbp-2@c000/disk@0
3. j. Next it is time to create the yaboot.conf file on the FireWire drive. The
config file shown below was based on the FireWire address above.
# pico /mnt/fw/boot/yaboot.conf ofboot=fw/node/sbp-2/disk@0: init-message=”Welcome top Yellow Dog Linux! \n Hit <TAB> for boot options. \n\n” partition=4 timeout=30 install=/usr/lib/yaboot/yaboot magicboot=/usr/lib/yaboot/ofboot default=linux image=/boot/vmlinux-2.4.20-8dsmp label=linux root=/dev/sda4 read-only initrd=/boot/initrd-2.4.20-8dsmp.gz defaultos=linux delay=10 enablecdboot
I believe the partition=4 line can go in the image= section which is where it belongs. If one has several boot images then a different partition might be needed. However, it was done this way for simplicity. Since this example only uses one FireWire drive with one install of YDL it is not necessary to move the line. The ofboot line should be the firmware path to the FirwWire drive.
3. k. Now we must “bless” the drive so that it can be seen by the Apple boot loader.
# ybin -v --boot /dev/sda2 --nonvram --config /mnt/fw/boot/yaboot.conf
3. l. You should now be ready to boot the FireWire drive using the Mac boot
loader. In order to get to the Mac boot leader you must restart the machine:
# shutdown –r now And hold down the keys: ALT + APPLE KEY + O + F
3. m. You should see a boot prompt and at this prompt type:
> boot fw/node/sbp-2/disk@0:2, yaboot
Note that the disk@0:2 is from the FireWire address and 2 is the bootstrap partition. This will change if you put the bootstrap on another partition number.
3. n. Now you should see the yaboot boot loader from the FireWire drive; you can just hit enter here and it will take you into YDL.
4: Firmware paths
To find the firmware path of your FireWire disk, type the command: ( find /proc/device-tree - name disk@\* | grep firewire ) Removing the /proc/device-tree gives the OpenFirmware path of the disk. Firmware aliases found in /proc/device-tree/aliases or lack of multiple firewire disks will allow a simplification of the path, as illustrated in our example.
