Booting to local partition / Boot grub from Pxe

Booting to local partition / Boot grub from Pxe
Hey,

I plan to deploy iPxe to my machines.
Since I can't flash it into the NIC, I will boot iPxe from grub, no problem so far.
IPxe fetches a script from the server via https and I got that part working nicely.
However, I will then need to be able to boot from a local partition: I know I can use 'sanboot --no-describe --drive 0x80'. But that just reloads grub from the MBR.
If iPxe is the default entry, this will boot iPxe again and I have a boot-loop.

Is there a way to directly boot a kernel from a local partition? I did not find anything in the command list, so probably not, since Ipxe probably does not understand how to read those filesystems.

Alternatively, is there a way to boot into a grub image on the PXE server?
I tried to generate a grub pxeboot image, using
Code:
grub-mknetdir --net-directory=/tftpboot/ --subdir=grubpxe
And then booting that entry via http with:
Code:
kernel http://.../files/grubpxe/i386-pc/core.0
boot
Grub starts, but reports 'error: file not found' and then goes into a rescue console.
If I could load a grub menu from the server, I will then be able to boot from a local partition.

Any help is appreciated
