For anyone who’s ever heard of linux, but is a little bit afraid of trying it out since normally it takes either the intenstinal fortitude to format your computer, or use an extra machine lying around, there’s a great resource called Knoppix that allows you to boot the cd and run the entire linux operating system in memory, without actually writing to your hard drive.
The cd can serve as a preview of what linux can be like on your machine (though obviously slower since it uses a lot of ram for temporary space, and is running off a cdrom), or it can be used for a rescue cd, or it can be used to base other custom bootable distributions off of. So if you’ve ever wondered about this linux thing and what it was all about, download a copy and try it out today under the hassle free, money back [It’s free] guarantee.
