Booting linux kernel with elilo on ia32 platform

[Guillaume Beretta]

Hi,

I've an EFI-firmware installed on ia32 plateform. I would like to boot a
2.6.27 linux kernel (32 bits) with an USB disk.
My bootloader used is elilo 3.8-ia32. I've created a FAT 32 partition on my
USB disk to put elilo, elilo.config and my kernel.
First of all, i would like to know the format of kernel image to use:
bzimage, elf (vmlinux), gzip elf (vmlinux.gz) ??? It's not clear !
I've tried to boot with this 3 formats but always the same problem of
reboot. Nevertheless, it seems to be my kernel was loaded in memory (log
with verbose option to 5).
Does my kernel need special options in his kernel configuration ???? I
already specify all options in relation with EFI.
Please see my log with an elf kernel image:

Can you please help me.

Thanks
