Syllable operating system family

The goal of the Syllable project is to create a family of easy-to-use free software operating systems. It is the continuation of the BeOS-like AtheOS. Syllable Desktop has its own C kernel with symmetric multiprocessing, multithreaded pre-emptive multitasking, high POSIX compliancy, 64-bit ... [More] journaled filesystem (AFS) with metadata, an integrated native GUI architecture with an object-oriented C++ API, SDL, singular native toolkit and multi-user desktop environment. The system seeks to be an integrated, lightweight, easy-to-program, powerful, high-performance graphical desktop environment which avoids legacy OS paradigms that frustrate developers and have hindered the computing masses' adoption of a free-software desktop. Syllable Server is a matching small and efficient Linux server. [Less]

monarc

Monarc Operating System KernelMonarc is an experimental and progressive operating system kernel; featuring modern architecture, clean code, and flexible structure. It is implemented in C/C++ and a small amount of assembly. The current platform is x86-32, and soon x86-64. You can see a screenshot of the early GUI here.

nanoos

Nano OSAn object oriented OS written in C++ and assembly. How toI recommend trying out the floppy disk image(very recent) first. Please download the disk image. use qemu or bochs to boot the image. After you satisfied your self please join the project and checkout the source. Play around and ... [More] understand what is happening where. then discuss here and try to implement small chunks and small functionality. I will suggest try out modifying the shell code to add few more commands. Next modify IStream subsystem to handle int, pointer, HEX etc... Present FeaturesMulti boot compliant (tested with GRUB) Hope it will work with syslinux too C++ minimal run time is present written as object oriented kernel 32-bit protected mode Memory manager for physical memory only CPU detection, Memory detection and IDE hard disk detection IDE hard disk read is possible Partion table parsing is in-built to IDE code FAT16 Partitions are recognised now To DoMemory manager will be re-written using paging(first priority) Chris Gheezee's Malloc implementation based on heap implemented. Multi tasking (second priority) application loading atleast elf and coff binary.(third priority) I am planning to create a driver template so that it will be easy to write drivers floppy driver IDE driver ( See changelog bellow) network stack (might be mu-tcp/ip) ether net driver for rtl series and NE2k NFS client side (too ambitious ) Modify IStream and OStream for better functionality. specially implemet getstring() in cin Filesystem atleast FAT-16 will be nice. (any help on this with reference to the present code will be highly appreciated) Somany more Note Help me to grow this embryo remember this is not going to compete with any other OS This is purely for Experimentation and Learning, Covered under GNU GPL-V2 if you find this interesting and want to contribute, I will be happy to accept your code change log9th december 2008: Kmalloc kfre krealloc implementation based on Chris gheeze's Heap based first fit allocator 18th december 2008: rudimentary dma and fdc code ported. 5th January 2009 : IDE hard disk driver is implmented. ( Only Reading) This works under BOCHS but not Under Qemu, I don't know Why??? 7th January 2009 : IDE driver in read_sector a minor bug is fixed, Partition Scanning is implemented. 13th January 2009 : IDE driver now works fine under BOCHS and qemu. cpuinfo now displays properly. 9th February 209 : A rudimentary FAT16 is implmented, It now only be used to check if the Kernel recognizes FAT16 partition or not. The Image Works with qemu. For details how to PLease Check the Wiki. 11th March 2010 : Few modification to malloc family in kheap.cpp Initial PCI code but not working, initial tasking code not tested, Use of class template for singleton class. multiboot class is derived from singleton template. 20th March 2010 : Multitasking of 4 task for done. This is just to test the context switch is working correctly. :) enjoy. [Less]

nexusos

NexusOS is a Open Source Unix-like Operating system for x86/i386 systems that is right now in pre-alpha/alpha stage. It will have a C++ GUI and and has C and Intel syntax ASM kernel. It uses GCC and NASM as well as make, bash, and ld for building.
