JaS and Grub Error

[aspire_5652]

installed Image: Mac OS X 10.4.8 [JaS AMD-Intel-SSE2-SSE3 with PPF1 & PPF2].iso

Hardware:

=> Laptop: ACER Aspire 5652 wlmi

- Intel Core Duo T2300(2x1,66GHz/FSB667)

- Chipset: Intel 945PM/GM

- nVidia GeForce Go 7600 256MB

- 1024MB DDR2

- 120 GB S-ATA

 

digest about my partitioning (fdisk -l, it's in german):

 

   Gerät  boot.	 Anfang		Ende	 Blöcke   Id  System
  /dev/sda1			   1		1149	 9229311	7  HPFS/NTFS (Win XP)
  /dev/sda2			1150	   14593   107988930	5  Erweiterte (extended)

  /dev/sda6   *	   11070	   12374	10482381   af  Unbekannt (MAC OS X)
  /dev/sda7		   12375	   12505	 1052226   82  Linux Swap / Solaris
  /dev/sda8		   12506	   14593	16771828+  83  Linux (SuSE)

 

I installed the Image on an extended partition, yes in know, it must be a primary partition, but there was no Space left on my HD, so it was the only chance to resize my extended partition and make a new partition and install MAC os there. The MAC installation did overwrite my MBR, after the succesfull installation Mac OS did boot correctly. But I have allready WinXP and SuSE Linux installed, and I want to boot them too. So I reinstalled Grub in order to boot XP, SuSE and MAC OS. Now XP and SuSE are bootable again. But I can't get MAC OS X working. I still tried different posted solutions.

 

Here my menu.lst entries:

 

title MacOSX
rootnoverify (hd0,7)
chainloader (hd0,5)+1

=> Error: HFS+ Partition error

 

title MacOSX
root (hd0,5)
savedefault (<- still tried without this entry)
makeactive
chainloader --force +1 (still tried: chainloader +1)

=> Error: Filesystem type unknown

 

(I installed PC_EFI, and followed the instructions, posted here http://forum.insanelymac.com/index.php?sho...p;#entry606752)

title MacOSX
root (hd0,7)
kernel /boot/boot_v8
boot

=> MAC booted, I can see the Apple approx. 2 seconds, the screen turns to dark grey and I get a message, that the computer must be rebooted manually

 

Is PC_EFI V8 compatible to JaS Mac OS X 10.4.8?

 

Does still anybody have a solution how i get MAC OS X working with grub?
