kernel image size

[Karthik Bala Guru]

Oh yuh,
I was into reducing linux kernel to around 256 kb ...
it was a futile attempt some 3 months back... !!
But i suppose that it will be acheivable with a
vast band of assembly programmers with tonnes of
time in hand !!!

yes, compiling older kernels on the newer ones
was never a success story in my experience !!

Try out asmutils ... It will give u enough idea.
It is much similar to tomsrtbt but gives 
clear idea to reduce linux kernel size !!

The smallest linux kernel in world is that of 
coventive technologies according to many newsgroups.

The smallest size achieved by me with MINIRTL ...
a tiny RTLINUX is that of around 450KB with many
supports removed !!
