kernel recompilation


hello,

i have changed some part of the sched/sch_generic.c file(ie some networking code)
now i need to see the changes.

i recompiled the kernel as below

make mrproper
make oldconfig // as i dont want anything new.
make dep
make bzImage

then i copied the new image and ........
the new sys is working
BUT
lsmod doesnt show any modules
lan is also not working.

and one more thing " even if i change a single line of some src in linux code do i need to do all the steps to recompile or i can i skip some "

please help or
provide any links

thanks Parag

one more thing ,even if i chg a single line of linux src i need to recompile .
DO we have to follow all the above steps or can we just use a subset of those.

Can u please provide some links on how to use timers in linux.
I need to collect pkts for some amt of time.......

yesterday we got the internet connection, the operator changed the ip addr of the sys.

now the problem is,
i followed ur steps (they were the effective)
but during rebooting ,the sys will stop at " bringing up eth0"
what might be problem.
waiting for ur reply,
