Help needed on bzImage

[Preeti Rani]

While booting, before entering into the file Head.S, it goes to the file
arch/i386/boot/setup.S where it does the job of loading the bzImage at
memory location 100000 (as what i have read from the internet source). What
I wanted to kow is that where can I get to know about the structure of
bzImage. I want to know about the mapping of bzImage to memory when the
compressed bzImage is actually loaded at that location.
