Info: Linux Installs on  desktop or laptop systems in roughly ## min.  It can be placed on a seperate partition and run alongside Windows, UNIX, Mac OS, etc and is available on some Silicon Graphics servers.  It is not a completely automatic installation process. The Red Hat installer is text-based, not GUI driven so you must scroll through text menus to pick your preferences and type your commands. Red Hat attempts to identify your SCSI devices- Ethernet cards, and graphics adapter automatically, however if it can't find out all the details you'll need to enter them yourself so, keep a complete list of your system's hardware handy.

Red Hat's GNOME (GNU Network Object Model Environment) GUI is a standard windows type interface.

BeOS understands common file types and disk formats, so you can read and copy files from other operating systems.  BeOS is expandable allowing the addition of  to four processors to meet your performance and productivity needs.

The actual OS code is very small and is able to load driver functionality when it needs it, and then free the memory afterwards. This keeps the kernel small and fast unlike other operating systems which load everything you need regardless of whether your system requires it or not.
