How to start Feather Linux?
 

I installed Feather linux and used Universal installer.....changed boot order when netbook is booting, click usb drive ..and 'Boot' showed up on screen. what does need to be type in there???

According to http://en.wikipedia.org/wiki/Feather_Linux

"With its most recent release being on 2005-07-04, Feather Linux is now dormant."

Netbooks didn't even exist in 2005 so it's unlikely your hardware is supported... maybe give a current distribution a try? Puppy Linux for example is a very popular and well documented option for running off a USB drive, you can read about more options at distrowatch.com. :)
