Subject: Re: Fast testing

Hmm,

Ok, I found this on internet:
"The bzImage file is in a specific format: It contains concatenated
bootsect.o + setup.o + misc.o + piggy.o.
  piggy.o contains the gzipped vmlinux file in its data section (ELF)
(see compressed/Makefile piggy.o)."

So after we make new bzImage and "somehow" extract these four .o files
than we can manually load
kernel image into memory ? We can just run same routines that are run
during the boot, but we can skip
everything till piggy.o file, because the vmlinux file is in piggy.o ?

thanks,
