[U-Boot-Users] "How to change the Magic number"

Hi ALL,

I have a specific requirement to change the Magic number of the linux kernel in my embedded system.

I cound see the Magic number is defined in U-boot files: 1.include/image.h:#define IH_MAGIC 0x27051956 2.cpu/ppc4xx/start.S: .long 0x27051956

So i can modify in u-boot to make it compatible to my Kernel (i am using montavista linux version 2.4.20), but i am not able to see this kindof info anywhere in the kernel source files. If anyone knows how the linux magic number is generated and what are the files need modifications inorder to change magic number please let me know.

Thnaks in Advance, Nagi
