Sure, we've seen projects like SplashTop
boot a stripped Linux build quickly, but Intel engineers at the recent Linux Plumbers Conference took things a little farther last Thursday, starting up modified versions of Fedora and Intel's own Moblin
Linux on an SSD-equipped Eee PC in just five seconds. That's all the way to an idle CPU and disk, not cheating and starting a window manager while background services thrash in the background, mind you -- and it's fast enough that the splash screen was removed from both distros. The changes are being sent back to the Moblin and Fedora trunks, but if you're curious, a detailed overview of the changes awaits at the read link.
