It has pre-emptive multitasking with threads, message-passing and virtual memory. It is currently targeted for the IA-32 processors, but the design is strictly separated into a hardware-dependent mechanisms layer, with an independent policy layer on top of that. It has its own basic boot loader that loads the kernel and a disk driver. It also has a basic text-mode display driver and keyboard driver. As with most microkernels, the drivers run in user space and help to demonstrate message passing and interrupts. When the system starts it loads a server that allows the user to load their own processes. There are very simple example user programs to demonstrate threads, message-passing and interrupts. The website is written like a textbook to explain how it all works, focusing on the implementation rather than theory. </p> </td> <td style="padding: 0 0 0 0px; width: 30%; vertical-align: top; font-size: 11px;"> <p><a href="/File:Icon_phone.png" class="image"><img alt="Icon phone.png" src="/images/4/4a/Icon_phone.png" decoding="async" width="16" height="16" data-file-width="16" data-file-height="16" /></a> <i><a rel="nofollow" class="external free" href="http://bluekernel.com.au/#intro,Download%20+%20Contact">http://bluekernel.com.au/#intro,Download%20+%20Contact</a></i><br /> </p><p><a href="/File:Icon_license.png" class="image"><img alt="Icon license.png" src="/images/3/38/Icon_license.png" decoding="async" width="16" height="16" data-file-width="16" data-file-height="16" /></a> <i>Creative Commons, <a rel="nofollow" class="external free" href="http://creativecommons.org/licenses/by-nc-nd/4.0/">http://creativecommons.org/licenses/by-nc-nd/4.0/</a></i><br /> </p><p><a href="/File:Icon_site.png" class="image"><img alt="Icon site.png" src="/images/2/23/Icon_site.png" decoding="async" width="16" height="16" data-file-width="16" data-file-height="16" /></a> <i><a rel="nofollow" class="external text" href="http://www.bluekernel.com.au">http://www.bluekernel.com.au</a></i> <br /> </p><p><a href="/File:Icon_floppy.png" class="image"><img alt="Icon floppy.png" src="/images/b/bd/Icon_floppy.png" decoding="async" width="16" height="16" data-file-width="16" data-file-height="16" /></a> <i>Floppy, 1.44 MB (at ./makefile change 20160 to 2880)</i><br /> </p><p><a href="/File:Icon_clock.png" class="image"><img alt="Icon clock.png" src="/images/e/e6/Icon_clock.png" decoding="async" width="16" height="16" data-file-width="16" data-file-height="16" /></a> <i> </i> <i>Latest update: 2018-12-15</i> </p><p><br /> </p> </td></tr></tbody></table> </div> <div style="margin: 0 0 10px 0; background-color: #FAFAFA; color: #000000; border: 1px solid #CEDFF2; padding:0.5em 0.5em;"> <table style="width: 100%; margin: 0; padding: 0; border: 0; border-collapse: collapse;"> <tbody><tr> <td style="padding: 0; width: 70%; vertical-align: top;"> <div style="float:right;padding-left:4px;padding-right:4px;"></div> <h2 style="margin:0;font-size:120%;border:none;font-weight:bold;text-align:left;color:#000;padding:0.0em 0.0em;"><span class="mw-headline" id="BoneOS">BoneOS</span></h2> <p>BoneOS is an Operating System for everyone built by everyone.

It was started in August 2017 with the objective of learning how a computer operating system works and to improve the coding skills of the main developer. The kernel is mostly written in C with some bits of assembly and has partial compatibility with C++ (a runtime is provided). Some of its features are: extensive HAL API, System V ABI compatibility, memory management, interrupt handling, VGA driver, timers and delays, some synchronization primitives, a growing home-made C library, virtual memory, a VFS, a keyboard and RTC driver and more.

Furthermore, Managarm supports many modern hardware devices, including USB 3 and has nearly full ACPI support. </p> </td> <td style="padding: 0 0 0 0px; width: 30%; vertical-align: top; font-size: 11px;"> <p><a href="/File:Icon_phone.png" class="image"><img alt="Icon phone.png" src="/images/4/4a/Icon_phone.png" decoding="async" width="16" height="16" data-file-width="16" data-file-height="16" /></a> <i>The official Managarm Discord server <a rel="nofollow" class="external free" href="https://discord.gg/7WB6Ur3">https://discord.gg/7WB6Ur3</a></i><br /> </p><p><a href="/File:Icon_license.png" class="image"><img alt="Icon license.png" src="/images/3/38/Icon_license.png" decoding="async" width="16" height="16" data-file-width="16" data-file-height="16" /></a> <i>Open source (MIT)</i><br /> </p><p><a href="/File:Icon_site.png" class="image"><img alt="Icon site.png" src="/images/2/23/Icon_site.png" decoding="async" width="16" height="16" data-file-width="16" data-file-height="16" /></a> <i><a rel="nofollow" class="external text" href="http://www.managarm.org">http://www.managarm.org</a></i> <br /> </p><p><a href="/File:Icon_floppy.png" class="image"><img alt="Icon floppy.png" src="/images/b/bd/Icon_floppy.png" decoding="async" width="16" height="16" data-file-width="16" data-file-height="16" /></a> <i>IMG, ~1GB</i><br /> </p><p><a href="/File:Icon_clock.png" class="image"><img alt="Icon clock.png" src="/images/e/e6/Icon_clock.png" decoding="async" width="16" height="16" data-file-width="16" data-file-height="16" /></a> <i> </i> <i>Latest commit: 2024-05-29, is active</i> </p><p><br /> </p> </td></tr></tbody></table> </div> <div style="margin: 0 0 10px 0; background-color: #FAFAFA; color: #000000; border: 1px solid #CEDFF2; padding:0.5em 0.5em;"> <table style="width: 100%; margin: 0; padding: 0; border: 0; border-collapse: collapse;"> <tbody><tr> <td style="padding: 0; width: 70%; vertical-align: top;"> <div style="float:right;padding-left:4px;padding-right:4px;"><a href="/File:MaslOS2-demo.png" class="image"><img alt="MaslOS2-demo.png" src="/images/thumb/b/bd/MaslOS2-demo.png/230px-MaslOS2-demo.png" decoding="async" width="230" height="132" srcset="/images/thumb/b/bd/MaslOS2-demo.png/345px-MaslOS2-demo.png 1.5x, /images/thumb/b/bd/MaslOS2-demo.png/460px-MaslOS2-demo.png 2x" data-file-width="1294" data-file-height="744" /></a></div> <h2 style="margin:0;font-size:120%;border:none;font-weight:bold;text-align:left;color:#000;padding:0.0em 0.0em;"><span class="mw-headline" id="MaslOS_2">MaslOS 2</span></h2> <p>MaslOS 2 is a goofy 64-bit OS written in C++.

Menuet's application structure is not specifically reserved for asm programming since the header can be produced with practically any other language.

Currently it is a single-user, multi-core, multi-tasking system that runs on bare hardware or on top of a host operating system (currently Microsoft Windows or Linux). The developers aim at producing a reliable, real-time operating system suitable for embedded systems and for industrial and in particular medical applications. Earlier it was called "Aos" (Active Object System), a nomenclature that is still in use. It is written in the Active Oberon programming language, which evolved from Oberon, a programming language in the Pascal/Modula tradition. The graphical user interface is referred to as “Bluebottle”.
