problem with XP loader and Leopard partition

[deesto]

I've copied a 'chain0' to the root of my XP partition (partition 1 of my main SATA drive), and added this to c:\boot.ini:

c:\chain0="OSX"

 

I have an iDeneb lite 10.5.8 new installation on the second partition of the same disk. When I boot this way and choose the "OSX" entry, the XP loader fails with:

Error 2: bad directory or file type

 

I've searched around and found several instances of this error, but haven't found a way to fix it so far. Any ideas?

 

BTW, I also have a working Fedora 12 installation on the same disk (partition 3 is the boot partition, and paritition 4 extended with a bunch of Linux partitions inside), and I haven't been able to get OSX to boot from a grub entry (with 'chainloader +1' or 'chainloader /boot/chain0'). Hints on a fix for either method would be great!

I've also tried adding 'boot' from PC EFI (by netkas) to my Linux /boot partition, but all grub.conf configuration attempts have resulted in either 'error 13: invalid or unsupported executable format' or 'error 17: cannot mount selected partition'. If I have Win XP (sda1/hd0,0), Leopard (sda2/hd0,1), and Linux /boot (sda3/hda0,2) all on the same partition, and grub is booting Linux and XP just fine, what do I need to do in order to get it to also boot the Leopard partition?
