Get a Mac IPod to work on x86 w/ native HFS+ support

[VisualPhoenix]

Ok guys... so until I get my ipod fixed and functional sometime tomorrow I'll let you all know exactly what I did to get it working...


Step 1:

Code: Select all

emerge sys-kernel/pfeifer-sources/pfeifer-sources-2.4.20.1_pre12.ebuild

Step 2 :

Code: Select all

download patches-2.4.21-pfeifer-r1_pre4.tar.bz2

Step 3:

Code: Select all

un-Bzip patches-2.4.21-pfeifer-r1_pre4.tar.bz2 and copy out the 017_hfsplus patch

Step 4 :

Code: Select all

Download http://www.ardistech.com/hfsplus/hfsplus-20030702.tar.gz

Step 5:

Code: Select all

Untar hfsplus-20030702.tar.gz

Step 6:

Code: Select all

Copy hfsplus-20030702/hfsplus/* files to /usr/src/linux-2.4.20-pfeifer-r1_pre12

Step 7:

Code: Select all

patch -p1 -d ../location/of/hfsplus_patch/017_hfsplus < /usr/src/linux-2.4.20-pfeifer-r1_pre12

Step 8 :

Code: Select all

cd /usr/src/linux-2.4.20-pfeifer-r1_pre12/fs/hfsplus

Step 9 :

Code: Select all

nano -w inode.c

 line 89 of inode.c:

-if (PageActive(node->page[i])) {
+if (PageActiveAnon(node->page[i])) {

Step 10 :

Code: Select all

cd /usr/src/linux-2.4.20-pfeifer-r1_pre12/kernel/

Step 11:

Code: Select all

nano -w ksyms.c
between line 280 and 281 of kernel/ksyms.c:
 
 EXPORT_SYMBOL(set_page_dirty);
 +EXPORT_SYMBOL(mark_page_accessed);
 EXPORT_SYMBOL(vfs_readlink);

Step 12:

Code: Select all

cd /usr/src/

Step 13 :

Code: Select all

rm linux

Step 14 :

Code: Select all

ln -s /usr/src/linux-2.4.20-pfeifer-r1_pre12 linux

Step 15 :

Code: Select all

Build kernel with File Systems>HFSPLUS built as a module

Step 16 :

Code: Select all

Enable Mac Parition Support in File Systems>Partition Types>Mac Partition Support

Step 17 :

Code: Select all

Save Kernel

Step 18 :

Code: Select all

 make dep && make clean bzImage modules modules_install

Step 19 :

Code: Select all

mount /boot

Step 20 :

Code: Select all

cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinux-pfeifer-2.4.20

Step 21 :

Code: Select all

nano -w /etc/lilo.conf

Step 22 :

Code: Select all

Add necessary lines for new kernel
MINE looks like:
# Linux bootable partition config begins
        image = /boot/vmlinuz-pfeifer-2.4.20-pre12
        initrd = /boot/initrd-pfeifer-2.4.20-pre12.gz
        root = /dev/sda3
        label = Pfeifer-2.4.20
        read-only # read-only for checking
#       #root = /devices/discs/disc0/part3

Step 23:

Code: Select all

run /sbin/lilo

Step 24:

Code: Select all

REBOOT AND GOOD LUCK!

[/code]

NOTE!!!! WARNINGS!!!! It is important you do the following each time you wish to mount or unmount your ipod!!!! NOTE!!!! WARNINGS!!!!

I make a dumb little script that does the following (I KNOW THIS CAN BE REVISED TO BE BETTER!!):

FILE: mount_ipod.sh

Code: Select all

echo "Cleaning up modules if they are running..."
rmmod sbp2
rmmod ohci1394
rmmod ieee1394
rmmod hfsplus
echo "Now mounting the IPOD... I hope its plugged in... You have 5 seconds."
sleep 1
modprobe hfsplus
sleep 4
modprobe ieee1394
sleep 5
modprobe ohci1394
sleep 10
mount /mnt/ipod

FILE: umount_ipod.sh

Code: Select all

echo "Unmounting Ipod"
umount /mnt/ipod
sleep 4
rmmod sbp2
sleep 4
rmmod ohci1394
sleep 4
rmmod ieee1394

IT IS IMPORTANT TO NOTE THAT ALL IEEE1394 DRIVERS MUST BE REMOVED BEFORE CONNECTING YOUR IPOD!

actually, the real kicker is ochi1394 -- i find that it crashes quite a bit if you only rmmod sbp2, remove the ipod, and expect it to act alright when you put it back in... As a precaution I suggest unloading all ieee1394 drivers before pluging in your ipod, then modprobing them -- and for unmounting, unmounting the drive, removing all modules, THEN unplugging the IPod.

GOOD LUCK AND HAPPY TESTING!

Also note that pfeifer-sources-2.4.21.1_pre4.ebuild has hfsplus support pre-built into the kernel... This guide is for people like me who want 2.4.20 support.

[VisualPhoenix]

That reminds me... If doing

Code: Select all

mount -t hfsplus /dev/sdXx /mnt/ipod 

returns errors about a bad superblock it is possible to correct it however i'm working on getting patches for the mac version of fsck and testing it...

WHATEVER YOU DO IF IT SAYS THAT YOU FAILED TO UNMOUNT THE IPOD AND TO RUN FSCK ON THE DRIVE DO NOT

I REPEAT

DO NOT RUN THE FOLLOWING COMMANDS!

WARNING DO NOT RUN

Code: Select all

 mount -nw -t hfsplus -o remount /dev/sdXx 

WARNING DO NOT RUN

Code: Select all

 mount -t hfsplus -force  /dev/sdXx 

DO NOT INSTALL

Code: Select all

 emerge hfsplusutils 

HFSPLUSUTILS can TANK your drive... IF you emerge it ONLY use it if you believe you have corrupted the superblock and want to try in desperation to back up your system. Its dubious that you will have success

[Kihaji]

Don't forget, for ease of use the difference between a Mac Ipod and a Windows Ipod is just a format away.

[VisualPhoenix]

true -- however apple users get newer firmware updates

[jerry arns]

Just a note to say that kernel 2.6.1 as HFS+ support and that there is no need to patch the kernel anymore.
I have a gentoo ppc on a iBook, and use my HFS+ iPod 15Gig with gtkpod and it works very well.

[uglyman]

WARNING DO NOT RUN
Code:
mount -nw -t hfsplus -o remount /dev/sdXx


WARNING DO NOT RUN
Code:
mount -t hfsplus -force /dev/sdXx

DO NOT INSTALL
Code:
emerge hfsplusutils

Hi I am trying to get my new ipod working with hfs+. I agree whole heartedly with the above mentioned advice, as I have screwed up my ipod several times with hfsplusutils this week. but my question is, if we get that error about cleanly unmounting.... what SHOULD we do? I am using the hfsplus support in the 2.6.9 (I think, I am at work now though) kernel. It seems that some people dont have the problem every time like I do and I am wondering if it is because I am using USB instead of firewire (gonna get a firewire card this week).

[uglyman]

hmm found this. I am about to try it. hopefully my house doesn't burn down:
http://svn.exactcode.de/t2/trunk/packag ... plus.patch
had to do it by hand... but it was pretty straight forward.

[uglyman]

working great so far!.... hope I am not speaking too soon.
