Banana is a 32-bit OS written in C and C++, designed for a 486 or better with at least 16MB of RAM. The kernel is pre-emptive and supports loading ELF drivers and modules from the disk. It runs on real hardware, and supports ATA/ATAPI/SATA/SATAPI/floppy disks, FAT/exFAT/ISO9660 filesystems, PS/2 keyboard and mouse, SB16 and AC97 audio. Banana also has ACPI support. It comes with an installer which can be run from floppies or a CD-ROM. Currently has a command line shell, and a GUI with solitaire, minesweeper, a photo viewer and text editor.
BleskOS is operation system fully written in assembly, with final goal to be usable for normal user. To 29/03/2022 there are drivers for VESA, AC97, Parallel ATA and ATAPI, Serial ATA, PS/2 keyboard, PS/2 mouse, our filesystem JUS, filesystem FAT32 and ISO9660, USB controllers OHCI, UHCI and EHCI, USB mouse, keyboard and mass storage devices, ethernet cards AMD PC-net and Intel e1000. There is also text editor, simple graphic editor of BMP files, player of WAV files, simple document editor and internet browser(only for HTTP pages now). Main BleskOS feature is another view of graphic user interface than mainstream of OSes. Every version is tested on real computers.
Today, FreeDOS is ideal for anyone who wants to bundle a version of DOS without having to pay a royalty for use of DOS. FreeDOS will also work on old hardware and embedded systems. FreeDOS is also an invaluable resource for people who would like to develop their own operating system. While there are many free operating systems out there, no other free DOS-compatible operating system exists. Sources are here: -stuff/freedos/files/repositories/1.2/
GreenteaOS is a 64-bit desktop OS for x86-64. Aims to run .exe files natively and become open-source Windows alternative. Follows own non-NT/non-UNIX monolithic kernel design. Currently in the pre-alpha state.
HeliX is a german open-source OS. It has a nice shell and already supports FAT12, multitasking, keyboards and mice and very, very much more... HeliX is still in development and it doesn't exist a long time , so there are many features to come! [at] this point of time there are no downloads at the webpage, because there are still some heavy bugs (; -please be patient; they'll come!
Hoho is an x86 open-source OS supporting multitasking with ELF executables, virtual memory, FAT and virtual filesystem, ATA drives and Floppy disks. Soon it will be self hosted with GCC working on top of it.
NexNix is designed to eventually be a powerful, safe, and modern operating system. In a way like Plan 9, it aims to take Unix and greatly improve on it, by making the filesystem more structured, being a true microkernel, implementing modern security measures, and being more GUI-centric. Unlike Plan 9, it aims to still be compatible with the wider Unix ecosystem wherever possible. Currently, it only uses i386, but in the future, ports are planned to MIPS (32 and 64), ARM, AArch64, and RISC-V (32 and 64).
OS for x86 with the goal to provide a complex system basics implemented with a maximum delay of 1 year (virtual memory, file systems, emulation, GUI, multitasking, clean-up of general information, drivers from other OSes, USB, SATA), and general study written in NASM, C and miscellaneous language snippets gathered from the usual PC demo code repositories, books, and study of professional programs. It aims at easily building a custom OS-like DOS application manually, simple or with all the available protection and system features, to study the implementation of the different system-level tasks. It contains simple 386 malloc/free functionality for paging, simple FAT32 LBA support for displaying files and folders with a simple fopen/readdir/Read_Disk/Read_Disk_DWORD for clusters, and several functions for handling VGA, PS/2, PIT timer, ATA-ATAPI. It boots from DOS and can return to it with the exittodos command, even under the newest laptops. Contains documentation in Spanish and English. Decompress the TAR to the root directory. c:\start.bat launches it. Has miniprograms that can be invoked as commands with arguments, and has fail-proof ATA-ATAPI detection (only primary master enabled by now). In 2021 it will add a basic emulator for being able to call things like video modes natively derived from the BIOS and to access the memory map from the kernel.
Plus operating system is hobby project. That's built to run as auxiliary OS with Major OS like Windows and Linux etc..bootable with grub2 and own boot loader.focused on eBook reading software(PDF,EPUB,MOBI,DJVU,CHM...).with programs like calculator, notepad,source code editor, hex viewer, text viewer,image viewer and many games.VESA 32bpp GUI from startup.read-only plus maybe writing support for standard file systems FAT/NTFS/EXT/CDFS.codec for archives(ZIP,RAR,7z,GZ ...).codec for image formats(JPG,BMP,GIF,PNG...).video player or at least thumbnails extract(AVI,MKV,MP4,3GP...). mountable as filesystem from ISO,ISZ file.generic drivers VBE,USB,HD Audio,Keyboard, mouse.bootable on qemu and of course on real computer systems.at least all drivers for one computer (my) this is primary goal.In summary goal is building a stable and usefull OS.A Project By Muhammad Arshad Latti.
QuasiOS is a x86 64-bit operating system which will be build from the ground up, currently in assembly and C, but will migrate to our own OSL (Operating System Language), when the compiler is ready. It have three main focus goals. A password capability-based system with cryptographic filesystem. A modularized kernel where the modules is hot swappable, hence updates can be made live. User friendly configuration and interaction.Some of the work are going to be our master theses for the next year, and we expect rapid development during our theses (2020-2021).
Silcos is a operating system that aims to provide a secure & robust environment for applications. It will sandbox all external executable files and also have advanced security in matter of object-management. It is in the development phase with the kernel being developed. The silcos kernel works in a modules which are dynamically loaded at runtime and divides itself into various modules like KernelHost, ModuleFramework, ObjectManager, and ExecutionManager, etc. It requires open-source support and will appreciate any!
Snowdrop OS is a small-scale 16-bit real mode operating system for the IBM PC architecture. Snowdrop was developed from scratch, using only assembly language. Snowdrop boots from a FAT12 filesystem (floppy disk) and comes with a shell, aSMtris (a Tetris clone), and a few other example programs that could greatly simplify the development - for example, see
Soso is a Unix-like 32bit operating system. Its features are multitasking with processes and threads, paging, Virtual File System, FAT32, system calls, basic Musl libc port, userspace ELF files, framebuffer (/dev/fb0), mmap, PS/2 mouse, Unix local sockets, and shared memory.
TempleOS is a 64 bit lightweight OS with multitasking and multicore support, which is ring-0-only and works in a single address space. It provides the interface for communicating with God: the user has to choose a random number from the constantly changing sequences and then it is converted to the text interpretation. Whole OS with its' software has been single-handedly created during 15 years by Terry A Davis - who also developed a programming language called Holy C together with a special compiler for it. TempleOS supports the FAT32 and RedSea filesystems (the latter created by Terry) and also the file compression. It doesn't support the networking, partially for ideological reasons, but there are forks available with added functionality
A unikernel environment based on the Free Pascal compiler and Lazarus IDE, initially targeting single board computers such as Raspberry Pi and also supporting QEMU the design is intended to be portable to other platforms. The modular architecture allows applications to pick and choose what features to use in a project and the compiler produces a bootable kernel image which includes all of the required RTL components. Comes with a comprehensive list of features including pre-emptive threading, multicore support, IPv4 networking, FAT/NTFS/CDFS file systems, USB support, SD/MMC support, drivers for common peripherals such as GPIO, I2C, SPI, PWM, and DMA, C library support, hardware accelerated OpenGL ES and OpenVG graphics and much more. Packaged in an installer download for Windows or as an install script for Linux customized versions of both Free Pascal and Lazarus IDE are included along with full source and a large collection of examples.
