New microkernel operating system for x86 computers, many features: network and Internet modules, file system (FAT); kernel handles memory, tasks, micro kernels, and some base devices: keyboard, video, hdd, and ramdrive.

Goal: scalability of highly parallel multicomputer systems. Based on small microkernel that does process management, interprocess communication; all other services are processes out of kernel. Processes and address spaces orthogonal, so Cosy process is like thread in other OSs. Hardware dependencies concentrated in areas of kernel for portability.

Includes links and brief descriptions of microkernal based operating systems.

By Christopher Browne. Brief, clear descriptions and critiquing of microkernel design concepts, with some links. Puts much current activity in larger context.

Goal: Provide modern functionality for a new OS layer and run most Amiga applications as efficiently as possible in a box environment with no Classic Amiga custom chips available.

By Trumpet Software International, 32-bit microkernel OS for x86 PCs coded in Object Pascal variant. Built from first principles to focus on small size, modularity, and be fully compatible with Win32 and industry standards; reads FAT-12/16/32. Low cost; free time-locked demo.

Effort to clone Windows NT OS; goals: to run without change Win32 programs (binary application compatibility), Windows NT drivers (binary driver compatibility); needs i486, 16 MB RAM, 40 MB free disk space. [Open Source, GPL]

Portable object-oriented microkernel OS, dynamically loaded device drivers, fully redesigned and rewritten many times in C++, runs on VAX, x86. Ongoing experiment in using O-O paradigm as framework for full OS, with distributed computing as main aspect in most design decisions.

SUpport for Multimedia in Operating systems, Lancaster University: microkernel OS with facilities to support distributed realtime and multimedia applications and ODP-based multimedia distributed application platforms.

Page listing several research projects: microkernel OSs (MK7, MK++, AD3) and other modules (CONVERSANT, CORDS, GIPC, SHAWS).

Teachable Operating System: tiny multithreaded messaging microkernel, in ANSI C; protected threads, memory managed, and thread/process control. From undergraduate course on concurrency, device programming, OS concepts. Descriptions, documents, theses, downloads, contacts, links. [Open Source, GPL]
