** a html formatted version of the following is available at http://www.orawski.com/~timon/debianppc-usb/index.php I highly reccomend looking at it there for legibility reasons ** You're in luck, I just set up debian on my iBook G4 this way yesterday. I can tell you it's working beautifully (i boot to linux by holding option down on boot and selecting the linux drive) and can try to help you through setting up your debian install on the drive. There are three things you need to do. 1. install debian onto the drive, setting up the partitioning like you would a normal internal drive (including apple bootstrap partition). d-i should do this automatically. 2. build a new initrd with usb modules and a modified linuxrc - i did this after letting the system reboot and booting from the cd again - in the installer, proceed up to the partitioning step then go to virtual console 2 (alt-fn-f2) i assume your target partition is /dev/sdb3 and your bootstrap partition is /dev/sdb2 now, mkdir /target mount /dev/sdb3 /target mount -t proc proc /target/proc chroot /target now, here comes the magic: you need to set up your mkinitrd scripts to build your initrd (and you'll need to remember to build a new initrd if you upgrade your kernel) using your favorite editor (vi or pico): edit /etc/mkinitrd/modules and add the lines: ehci-hcd usb-storage scsi_mod sd_mod create a new file /etc/mkinitrd/scripts/sleep as follows #!/bin/sh cp /bin/sleep $INITRDDIR/bin case "$VERSION" in 2.4.*) LD_ASSUME_KERNEL=2.4 export LD_ASSUME_KERNEL ;; esac for i in `ldd /bin/sleep /usr/bin/awk | sort -u | awk '{print $3}'` do mkdir -p `dirname $INITRDDIR/$i` cp $i $INITRDDIR/$i done #EOF edit /usr/share/initrd-tools/linuxrc and insert the following lines after mount -nt proc proc proc echo "Loading USB Modules" /sbin/modprobe usbcore /sbin/modprobe scsi_mod /sbin/modprobe sd_mod /sbin/modprobe usb-storage /sbin/modprobe ehci-hcd sleep 5 then run mkinitrd -o /boot/usbinitrd-`uname -r`.img `uname -r` 3. install yaboot onto your usb hdd's bootstrap partition. you need to find out the openfirmware path of your usb hdd cd /proc/device-tree find * | grep usb | grep disk as an example, mine is: /[EMAIL PROTECTED]/[EMAIL PROTECTED],1/[EMAIL PROTECTED] so, now you're going to want to create /etc/yaboot.conf mine is as follows: --- begin file yaboot.conf --- boot=/dev/sda2 ofboot=/[EMAIL PROTECTED]/[EMAIL PROTECTED],1/[EMAIL PROTECTED]:2 device=/[EMAIL PROTECTED]/[EMAIL PROTECTED],1/[EMAIL PROTECTED]: init-message="Welcome to USB Debian PPC\n\n" partition=3 timeout=10 install=/usr/lib/yaboot/yaboot magicboot=/usr/lib/yaboot/ofboot default=linux-usb image=/[EMAIL PROTECTED]/[EMAIL PROTECTED],1/[EMAIL PROTECTED]:3,/boot/vmlinux-2.6.8-powerpc label=linux-usb read-only initrd=/[EMAIL PROTECTED]/[EMAIL PROTECTED],1/[EMAIL PROTECTED]:3,/boot/usbinitrd-2.6.8-powerpc.img root=/dev/sda3 defaultos=linux delay=10 enablecdboot --- end file yaboot.conf --- then just run ybin -v and reboot ** i think you can run ybin -v --nonvram instead and not have to reset the pmu to restore os/x as the default boot -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
