modifying the original Linux kernel, say 2.6.34, to make it running as OS
 

How can I modify the original Linux kernel, say 2.6.34, to make it running as my OS ? (ACTUALLY IN VIRTUAL BOX


please note that :
------------------

1. I AM NOT ASKING YOU HOW TO USE VITUAL BOX. I KNOW IT. BUT I'VE WRITTEN IN THE QUESTION, JUST TO BE CLEAR.

2. I AM NOT ASKING TO SIMPLY UPGRADE MY KERNEL. RATHER, I WANT THE LINUX KERNEL TO WORK AS MY OS.

3. I DON'T BOTHER ABOUT COMMAND LINE OR GUI. ALL THAT I WANT IS TO JUST MAKE THE KERNEL RUNNING.

You can't. Hence the whole GNU/Linux thing - Linus created the kernel and needed a toolset to turn it into an OS. GNU had a toolset and needed a kernel. Have a look at the LFS Book, there are a set of very basic tools you need to make the kernel boot - once it has booted you will have an extremely minimal system.

thank you brother for your kind help.

but a doubt is there..
what was there in the first original linux then?
was it not an independent OS ?

okay .. so what is that toolset ?? can you please explain a little bit ??

In my sig, there is a link to a chart showing all the Linux distros and where they came from. Get it here: http://futurist.se/gldt/wp-content/uploads/gldt1005.png

The toolset is everything that is not the kernel. Read up on the history here: http://en.wikipedia.org/wiki/History_of_Linux and here: https://netfiles.uiuc.edu/rhasan/linux/

This is sounding like a question of semantics. Perhaps you could tell us what you mean by 'OS'? The strict definition that most pedants would use is that the kernel IS the OS.
Given that, the method of getting the kernel 'working' is to launch it with a bootloader such as LILO, Grub, or PXE. But I don't think this is really what you are asking. Or is it?

I read it as he wants to run only the kernel - no other programs. AFAIK, that won't work, you need a minimal set of programs to do this.

That seems like a reasonable interpretation. The last selection in the poll makes me think he is confused about what a kernel is. Making a new kernel does not produce a drastically different distro.

@ theNbomr:

thanks for your kind help. I know that only kernel is not sufficient to make any os to run but i am talking about the custom as well as minimized os (having grub boot loader and all other 'MUST' components ).. which just loads the core component of the linux kernel. and i wanted to ask the same in the polls to find people like me.

I don't know of what value your extreme minimalist configuration would be, but as I see it, you could easily set up a bootloader to launch an arbitrary kernel, and pass as the init process, only a simple do-nothing program. To test how this might go, simply boot almost any system that uses grub, and at the boot prompt, enter edit mode. Edit the command line, replacing the 'init=' argument with 'init=/bin/bash'. When it boots, you will have an almost-minimal OS with only a running kernel and a shell. This is basically single-user mode.
There are toolkits available that provide a means to produce a minimal, or however complex distro you require. One that I have tried is buildroot, which perhaps would be useful to you.

can you tell me specifically that what to do to attach grub code to Linux kernel ?
I am a rally newbie and don't know what to do after downloading the source code of GRUB and Linux kernel :-(

Well, after you build the kernel and grub, you'll want to install grub to a device (say a hard drive). I usually install grub like this (use your device instead of hda1):
After the install, look for a folder on your device (usually boot/grub/) that contains the grub files. A file menu.lst should contain something like this:
If you can find the grub manual you can probably find more information.
Then just make sure your device has the boot flag set (see man fdisk), check, check, and check again, and then reboot.

You are presently running some distribution. Look in grub.conf (may be called menu.lst), probably located in /boot and see how it is done there. Of course, in your minimalist setup, you won't want to run init, but something much smaller.

Voted for kUbuntu but..
 

Although I use kUbuntu, Most of my other PC's are using "slitaz (installed)".
