OpenZaurus is a defunct embedded operating system for the Sharp Zaurus personal mobile tool PDA.
In its original form, the project was a repackaging of the SharpROM, the Zaurus's factory supplied kernel and root filesystem image. In order to make the Zaurus's OS closer to the needs of the developer community, the SharpROM was altered through the use of bugfixes, software additions, and even removals in order to make the package more open.
The OpenZaurus project was revamped completely, becoming Debian-based built from source, from the ground up. Due to the change in direction, OpenZaurus became quite similar to other embedded Debian-based distributions, such as Familiar for the iPAQ. OpenZaurus, in its current form, facilitates an easy method for users to build their own custom images. The efforts of Openzaurus, along with other embedded Linux projects, were integrated into the OpenEmbedded Project, which now provides the common framework for these projects.
In addition to building a custom OpenZaurus image using OpenEmbedded metadata, The OpenZaurus distribution can be acquired in three variations for each version release.
On April 26, 2007, it was announced [1] that the OpenZaurus project was over. Future development efforts are to focus on the Ångström distribution for embedded systems.
A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. They are often obtained from the website of each distribution, which are available for a wide variety of systems ranging from embedded devices and personal computers to servers and powerful supercomputers.
The iPAQ is a discontinued Pocket PC and personal digital assistant which was first unveiled by Compaq in April 2000.
GoboLinux is a Linux distribution whose most prominent feature is a reorganization of the traditional Linux file system. Rather than following the Filesystem Hierarchy Standard like most Unix-like systems, each program in a GoboLinux system has its own subdirectory tree, where all of its files may be found. Thus, a program "Foo" has all of its specific files and libraries in /Programs/Foo, under the corresponding version of this program at hand. For example, the commonly known GCC compiler suite version 8.1.0, would reside under the directory /Programs/GCC/8.1.0.
Windows Embedded Compact, formerly Windows Embedded CE, Windows Powered and Windows CE, is a discontinued operating system developed by Microsoft for mobile and embedded devices. It was part of the Windows Embedded family and served as the foundation of several classes of devices including the Handheld PC, Pocket PC, Auto PC, Windows Mobile, Windows Phone 7 and others.
The Sharp Zaurus is the name of a series of personal digital assistants (PDAs) made by Sharp Corporation. The Zaurus was the most popular PDA during the 1990s in Japan and was based on a proprietary operating system. The first Sharp PDA to use the Linux operating system was the SL-5000D, running the Qtopia-based Embedix Plus. The Linux Documentation Project considers the Zaurus series to be "true Linux PDAs" because their manufacturers install Linux-based operating systems on them by default. The name derives from the common suffix applied to the names of dinosaurs.
GPE is a graphical user interface environment for handheld computers, such as palmtops and personal digital assistants (PDAs), running some Linux kernel-based operating system. GPE is a complete environment of software components and applications which makes it possible to use a Linux handheld for tasks such as personal information management (PIM), audio playback, email, and web browsing.
Qt Extended is an application platform for embedded Linux-based mobile computing devices such as personal digital assistants, video projectors and mobile phones. It was initially developed by The Qt Company, at the time known as Qt Software and a subsidiary of Nokia. When they cancelled the project the free software portion of it was forked by the community and given the name Qt Extended Improved. The QtMoko Debian-based distribution is the natural successor to these projects as continued by the efforts of the Openmoko community.
Computer operating systems based on the Linux kernel are used in embedded systems such as consumer electronics, in-vehicle infotainment (IVI), networking equipment, machine control, industrial automation, navigation equipment, spacecraft flight software, and medical instruments in general.
OpenEmbedded (OE) is a build automation framework and cross-compile environment used to create Linux distributions for embedded devices. The framework is developed by the OpenEmbedded community, which was formally established in 2003. OpenEmbedded is the recommended build system of the Yocto Project, which is a Linux Foundation workgroup that assists commercial companies in the development of Linux-based systems for embedded products.
AppImage is an open-source format for distributing portable software on Linux. It aims to allow the installation of binary software independently of specific Linux distributions, a concept often referred to as upstream packaging. As a result, one AppImage can be installed and run across Ubuntu, Arch Linux, and Red Hat Enterprise Linux without needing to use different files. It aims to be a format that is self-contained, rootless, and independent of the underlying Linux distribution.
Nexenta OS, officially known as the Nexenta Core Platform, is a discontinued computer operating system based on OpenSolaris and Ubuntu that runs on IA-32- and x86-64-based systems. It emerged in fall 2005, after Sun Microsystems started the OpenSolaris project in June of that year. Nexenta Systems, Inc. initiated the project and sponsored its development. Nexenta OS version 1.0 was released in February 2008.
Squashfs is a compressed read-only file system for Linux. Squashfs compresses files, inodes and directories, and supports block sizes from 4 KiB up to 1 MiB for greater compression. Several compression algorithms are supported. Squashfs is also the name of free software, licensed under the GPL, for accessing Squashfs filesystems.
Wubi is a free software Ubuntu installer, that was the official Windows-based software, from 2008 until 2013, to install Ubuntu from within Windows, to a single file within an existing Windows partition.
The Linux booting process involves multiple stages and is in many ways similar to the BSD and other Unix-style boot processes, from which it derives. Although the Linux booting process depends very much on the computer architecture, those architectures share similar stages and software components, including system startup, bootloader execution, loading and startup of a Linux kernel image, and execution of various startup scripts and daemons. Those are grouped into 4 steps: system startup, bootloader stage, kernel stage, and init process. When a Linux system is powered up or reset, its processor will execute a specific firmware/program for system initialization, such as the power-on self-test, invoking the reset vector to start a program at a known address in flash/ROM, then load the bootloader into RAM for later execution. In IBM PC–compatible personal computers (PCs), this firmware/program is either a BIOS or a UEFI monitor, and is stored in the mainboard. In embedded Linux systems, this firmware/program is called boot ROM. After being loaded into RAM, the bootloader will execute to load the second-stage bootloader. The second-stage bootloader will load the kernel image into memory, decompress and initialize it, and then pass control to this kernel image. The second-stage bootloader also performs several operation on the system such as system hardware check, mounting the root device, loading the necessary kernel modules, etc. Finally, the first user-space process starts, and other high-level system initializations are performed.
The Ångström distribution is a defunct Linux distribution for a variety of embedded devices. The distribution is the result of work by developers from the OpenZaurus, OpenEmbedded, and OpenSIMpad projects. The graphical user interfaces (GUIs) available are OPIE and GPE among other options.
Linux for mobile devices, sometimes referred to as mobile Linux, is the usage of Linux-based operating systems on portable devices, whose primary or only Human interface device (HID) is a touchscreen. It mainly comprises smartphones and tablet computers, but also some mobile phones, personal digital assistants (PDAs) portable media players that come with a touchscreen separately.
FBReader is an e-book reader for Linux, Microsoft Windows, Android, and other platforms.
Familiar Linux is a discontinued Linux distribution for iPAQ devices and other personal digital assistants (PDAs), intended as a replacement for Windows CE. It can use OPIE or GPE Palmtop Environment as the graphical user interface.
