Grub2 load modules
Posted: Fri Jan 30, 2015 1:33 am
Hi guys,
I am planning to use grub2 to load 64-bit kernel as a module and jump to it from 32-bit multiboot-complaint kernel.
My grub.cfg is
(kernel64.mod is in /boot/grub/i386-pc/)
The problem is grub says "invalid arch-dependent elf magic" and I'm pretty sure it happens when I try to load kernel64 module(without insmod kernel64 it works well).
kernel64 and kernel32.bin are linked as a flat binary file.
So how do I solve the problem and are there any specific requirements on the format of grub2 modules?
Please note that : I tried to google it and google gave me all "reinstall grub2" garbage from ask ubuntu.
Thanks for you time!!
