Isn't the Atom x86 code compatible? If this is a standard PC motherboard just start by attaching a HD, DVDrom drive, memory, kb, network, mouse, memory, and power supply and just boot a Linux CD. OR boot using an image on a USB flash stick. If the motherboard supports booting via TFTP off of a network you can set up a TFTP server on another computer (probably not worth the effort at this point).
ANY Linux distro will work, but to start off small Slackware is a good choice. If you don't mind reading the manuals Arch Linux is also a good choice, but it isn't as easy to install. Debian is also good, use the non-graphical install and do NOT select any packages in the final step (command line only none graphical desktop) ... unless you WANT to run a GUI desktop, then pick LXDE or XFC at the start from the 'alternate desktop' menu at boot time.
Please suggest some good tutorial
EDIT: should get you here http://www.howtoforge.com/roll_a_kernel_debian_ubuntu_way
Personally I'd implement a command line Ubuntu (get the "alternative" CD)
There's also 'Linux from scratch'
thanks, i will try at my end.
