Hi,
I want to install Lion in my Dell Inspiron N4050.
I try iAtkos L2, but no success even after several custom settings

Specs:
Intel Pentium B950 2.1 GHz
3 GB RAM
AMD Radeon hd 6470

Is it possible to Run Lion on it?

If Yes, is there a well explained Tutorial?

Thanks for your answers.

yes.

1.) download, install and run OSX ML / SL / Lion / etc in a Virtual Box. or if you have a real MacOS, just use it.
2.) download Lion OS Disk (from ThePirateBay).dmg.
3.) put the dmg to the applications.
4.) download and install unibeast and install to a flash drive.
5.) download MyHack, creat OSX installer, the choose the version. install to a 8GB or more Flash drive.
6.) restart comp, plug the uni beast flash drive and the MyHack flashdrive, boot to the unibeast FD.
7.) when loaded, select "MyHack OSX Installer", type: -v -f npci=0x3000 PCIRootUID=1
8.) installer loaded. open utilities > disk utility
9.) take a partition to install, click on the "Erase", then select MacOSX Extended (Journaled).
10.) install there.
done

*Flash drives must be formatted to GUID Partition Table (GPT), not Master Boot Record (MBR)
*Partition must be changed to GPT first using Minitool Partition Wizard.
*if you have a Mac OSX Disk (whether you bought it or comes with your MacOS), you can skip 1-5.

Guides to install osx on VBox is available on Google.

Don't ask me about Post installation. I'm working on it too. just use Multibeast and that's all.
