I compared Moblin 2.1 and Chrome OS before time.

Project page Moblin 2.1: http://moblin.org Chrome OS : http://www.chromium.org/chromium-os

Kernel Moblin 2.1: 2.6.31(-netbook, -ivi, -menlow, -mrst) Chrome OS : 2.6.31(-chromeos-intel-menlow) but It isn’t included psb driver Currently, I think this kernel is for netbooks, CULV laptops

Base distribution Moblin 2.1: Original Chrome OS : Ubuntu Karmic

Kernel parametor Moblin 2.1: vga=current quiet root=/dev/sdx (no initrd) Chrome OS : (USB) quiet console=tty2 initrd=initrd.img init/sbin/init boot-local rootwait root=LABEL=C-ROOT ro noresume noswap i915.modeset=1 loglevel=1 (HDD) quiet console=tty2 init/sbin/init boot-local rootwait root=/dev/sda ro noresume noswap i915.modeset=1 loglevel=1
