Silly question about custom boot image

[Guest oernii]

I wan to modify my boot image. However, when I split the dumped original image (~3MB) and reassemble it with mkbootimg it is quite smaller. Only 2,2MB in fact. One splitting tool gave me a warning about a possible 3rd part besides the kernel and initrd. What could that be, and do I need it? Will my phone work when i flash the yet unmodified new boot image?

than you for you time.

Only 1 way to find out! And if you're not up to that type of experimentation I'd leave modifying the boot image :)

Alternatively, why not just use this all in one splash/boot/recovery tool? http://forum.xda-developers.com/showthread.php?t=794638

Some info I read earlier.

Have you looked into AnyKernel by Koush? :)

this is exactly what I have read. Unfortunatelly no explanation whatsoever about the 3rd part of the boot image. I will have to try it ;-)

@BashyUK I want to create some special mounts, dirs & config files. no animations etc ;-) My phone has already CMrecovery and root.
