problem with gunzip()

Hi

When I ported linux to a board with MPC860, 16M RAM and 2M Flash,
I met a problem.
After the program gunzip()(misc.c) the vmlinux image to address 0x0,
the contents from 0x0 to IMAGE_SIZE should be as same as that in
linux/vmlinux, right? I found that they are not same. Only from 0x0
to about 0xb500, they are same.
I don't think gunzip() has any problem.
Do you have any suggestions?
Thanks!
