GRUB Legacy fails to chainload Arch /boot/grub/i386-pc/core.img

Installing GRUB2 (grub-bios) in Arch I chosen "Generate core.img alone" option in GRUB2 wiki. This, according to the article, "requires another BIOS bootloader like grub-legacy ... to be installed to chainload /boot/grub/i386-pc/core.img".

Ubuntu Lucid GRUB Legacy is installed in /dev/sda MBR and its menu.lst contains following lines to chainload new Arch installation:

title        Arch Linux 2012.8.04 (/dev/sda3)
root            (hd0,2)
kernel    /boot/grub/i386-pc/core.img

While trying to boot GRUB Legacy hangs up on the last line.  No error messages.

The task seems to be trivial, however does not work.  Could anybody enlighten me on this, please?

P.S. 
I followed GRUB2 wiki instructions to the letter and after populating the /boot/grub directory and generating a /boot/grub/i386-pc/core.img file
proceeded with the next section to generate a configuration for GRUB2 by executing:

# grub-mkconfig -o /boot/grub/grub.cfg

I'm not sure if this was needed considering I opted to "Generate core.img alone" option.  I wonder if it could be the source of my problem?  Though I do not see how it could affect core.img file which I'm trying to chainload directly.

Re: GRUB Legacy fails to chainload Arch /boot/grub/i386-pc/core.img

Yes, you still need a .cfg file. That's the whole point... install a bootloader and configure it, which in GRUB (2)'s case, you use a command to automatically generate the .cfg (or at least it's the "recommended" method). Anyway, GRUB Legacy support has been dropped from Arch Linux: http://www.archlinux.org/news/grub-lega … supported/ and this is the Arch Linux support forum, not the Ubuntu support forum.
