Etlinux is a complete Linux-based system designed to run on very small industrial computers. It has been designed to be small, modular, flexible and complete. Its reduced memory and disk requirements make it ideal for all cost-sensitive situations, while at the same time its modularity and completeness give the full power of unix even for embedded applications.

What is Etlinux useful for?
Etlinux is ideal in all embedded system applications where advanced unix facilities are a must: preemptive multitasking, multithreading, memory protection, fast I/O, enhanced reliability, speed, ...
Moreover, source code availability is a guarantee for the longevity of Etlinux based products.
But perhaps the greatest advantage over competitors is given by the enormous and proven availability of advanced development tools, documentation and sources, giving an effective edge to the developer and reducing the time to market. In fact the availability of constantly updated quality C/C++ compilers, debuggers, libraries, interpreted languages, and other tools is the most compelling reason to switch away from old proprietary embedded development environments.

Etlinux specific features
Etlinux has some unique features, that distinguish it from other linux-based embedded solutions:

• embedded cgi-capable WEB server
• a telnet server
  an email server, with the ability to execute commands sent by email from a remote site
• CORBA support
• easy-to-use remote file management
• the powerful Tcl scripting language
• a flexible package selection scheme, allowing an easy customization of the system
• source code available for every component

Requirement
Minimal requirements for an Etlinux system are amazingly reduced:

• Intel-compatible 386SX processor (or better)
• 2MB of RAM
• 2MB of disk (HD or M-Systems DiskOnChip)
