EtLinux is a complete Linux-based OS distribution designed to run on very small industrial and embedded 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 Linux/UNIX facilities are a must: preemptive multitasking, multithreading, memory protection, fast I/O, enhanced reliability, speed, etc. 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 browser
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

System Requirements

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)

Is it free?

Like every product released by Prosa Srl, EtLinux is free software and is distributed with full source code. Our code is released under the GNU PUBLIC LICENSE (GPL) (some
accompanying packages have different licenses, but they all qualify as Open Source).

EtLinux development has been sponsored by EuroTech Spa (www.eurotech.it), in order to have a reliable Operating System for their own embedded PC/104 systems. Although EtLinux includes device drivers for EuroTech peripherals, it is pretty general, and can run on almost any Intel x86 based industry standard PC.
