C-BIOS is an open source BIOS for MSX computers. C-BIOS can be shipped with MSX emulators so they are usable out-of-the-box. This project aims to improve C-BIOS by fixing incompatibilities with the MSX BIOS and the development of a Disk ROM.

The scsirastools package adds several Linux SCSI tools that can be used to service and maintain disk storage devices. It handles SCSI, Linux SW RAID, SAS, SATA, and USB devices via SCSI emulation. For details & rpms, see http://scsirastools.sf.net.

Multiband Atheros Driver for WiFi (MADWIFI): Linux driver for 802.11a/b/g Cardbus/PCI/MiniPCI cards using Atheros chipsets. *** Attention: homepage moved to http://madwifi-project.org - files from sf.net CVS deprecated! ***

This project reimplements from scratch the RPL language made popular by HP programmable calculators, in portable C/C++. The main goal is to release a complete computing environment for various targets. There's currently 4 active targets: the HP 50g, HP39gs and HP40gs calculators and a PC simulator (see the downloads section!). Other ports are planned for the future.

This project contains software for 'personalizing' the NSLU2 network storage device, manufactured by Linksys. None of this material was written or contributed by Linksys. The NSLU2 is run by embedded Linux, and as such, is perfect for 'personalization

This is a small library that allows comunicating with a Webasto (tm) W-Bus capable car heating system. Runs on Personal Computers or for embedded devices (slim design). Easily portable. Includes a Heater manager, heater controller program and more. The GIT repository (CVS is deprecated) also includes a control unit application to control W-Bus capable devices, a W-Bus compatible heater unit firmware application and a heater simulator for testing purposes. Also, a serial port loop back driver for linux is included to simulate OBD II K-Line adapters.

Nuttx is a real time embedded operating system (RTOS). Its goals are: (1) small footprint usable in deeply embedded, resource constrained environments, (2) fully scalable from tiny (8-bit) to moderate (32-bit), (3) standards compliance, (4) real time, and (5) totally open. Think "Tiny Linux". NuttX is now and Apache project in incubation. See https://nuttx.apache.org/download/ for the latest downloads.

GPL source and toolchain for ASUSTOR NAS

TinyOS is an operating system for embedded sensors and networks. Versions 2.0 and later of TinyOS should be downloaded from www.tinyos.net.

MinopsOS is a tiny operating system for PC computers. It's small enough to fit inside the boot sector of a floppy disk.

HelenOS is a portable microkernel-based multiserver operating system written from scratch. It decomposes key operating system functionality such as file systems, networking, device drivers and graphical user interface into a collection of fine-grained user space components that interact with each other via message passing. A failure or crash of one component does not directly harm others. HelenOS is therefore flexible, modular, extensible, fault tolerant and easy to understand. HelenOS does not aim to be a clone of any existing operating system and trades compatibility with legacy APIs for cleaner design. Most of HelenOS components have been made to order specifically for HelenOS so that its essential parts can stay free of adaptation layers, glue code, franken-components and the maintenance burden incurred by them.

Unix-like operating system for the TI-89 and TI-92+ graphing calculators.

The aim of our project is to create a portable microkernel and a set of OS services that allow good local performance, multiple concurrent operative system personalities (ie UNIX and a native interface) and easy integration of distributed components.

Provide secure and stable OS, based on highly modified Linux Kernel, own package system, like "BSD Ports". Compatible with x86, Power PC. Easy to use of any level users. Complete Documentantion in many languages. 99% compatible with Windows.

This project has been moved to http://pros.cs.purdue.edu/ PROS is a lightweight and fast alternative operating system for the VEX Cortex Microcontroller. It features multitasking, low-level control, and Wiring compatible functions to harness the full power of the Cortex. With a real-time kernel based on FreeRTOS and a development environment built on Eclipse CDT, PROS uses proven software to increase the reliability and usability of the VEX development system across all three major computing platforms. PROS is currently under active development to make it usable for VEX high school and middle school teams. PROS is intended for advanced VEX users seeking to move beyond competing environments. Eclipse and FreeRTOS have their own licensing agreements. Please see http://www.eclipse.org/legal/epl-v10.html and http://www.freertos.org/a00114.html for details.

LiveCD is a "Complete FreeBSD System running on CD".

A Linux port of the OpenBSD/FreeBSD Cryptographic Framework (OCF). This port aims to bring full asynchronous HW/SW crypto acceleration to the Linux kernel, OpenSwan, OpenSSL and applications using DES, 3DES, AES, MD5, SHA, PublicKey, RNGs and more.

An implementation of the Ext2 (Linux) filesystem for Mac OS X.

MikeOS is a an open source 16-bit operating system for x86 PCs, written in assembly language, which boots from a floppy disk or CD-ROM. It is designed as a learning tool for x86 assembler and basic OS design.

Here you can find both an Oberon V4 system for Linux (x86) and a collection of Oberon V4 sources for various other platforms. Oberon V4 was implemented at ETH Zurich for several platforms. Binaries can be found on their server[1] and on the one of the University of Linz[2] where Mössenböck's group did further development after he left ETH and the Group at ETH concentrated on System 3. More Information can be found in the wiki https://sourceforge.net/p/oberon/wiki/Home/ of this Project and on Wikipedia https://en.wikipedia.org/wiki/Oberon_(operating_system). In 2013 they were moved here for easy access and, in case of interest, collaboration on further development. The Oberon mailing list[3] is an established channel for its discussion and followed also by the administrators of this SF project.

Recursive LDD (recursive-ldd) is a Perl script that allows displaying a tree-like hierarchy of shared library dependencies. The script calls on the standard Linux ldd utility in a recursion for every listed binary and library. It completes running when no matches are found in the current branch. It can also print unique values only as well as environment variables that affect the loading of libraries: LD_LIBRARY_PATH and LD_PRELOAD. Same limitations to standard ldd apply. Recursive-ldd cannot check libraries without read permissions.
