 | | MACH is designed to support computing environments consisting of networks of uniprocessors and multiprocessors. | | | To enhance performance, a memory manager may allow a MACH kernel to maintain its memory cache for a memory object after all virtual address space references to it are gone, by asserting the caching parameter to the memory_object_set_attributes call. | | | Ports of MACH to other computers are in progress. |

| | Initial Investigation of Mach and Chorus |
| | Mach and Chorus will now be compared from the viewpoint of assessing the amount of effort required to port them to the Mars and Leopard-2 computers. | | | The goal of the Mach project is to provide a simple extensible Unix compatible kernel suitable for the next generation of computer systems. | | | Mach is a Bsd 4.3 Unix based operating system developed at Carnegie-Mellon University that provides binary compatible with Bsd 4.3. |

| | The Mach 4 Project |
| | The goal of the Mach 4 project is to investigate some new research ideas, fix the major problems of Mach 3, and provide the base needed by the Flux project, ending up with a fast, flexible, functional kernel worthy of being called Mach version 4. | | | Mach can be compiled using native build tools on Linux, BSD, Mach+UX, and Mach+Lites, and can be cross-compiled from any environment on which you can build the necessary GNU cross-development tools. | | | OSF Mach project: The Open Software Foundation is doing lots of work with two versions of the Mach kernel (Mach 3 and MK++) and the "AD2" operating system servers above Mach. |

| | Guide to Porting Mach |
| | The machine dependent files needed to produce a basic version of Mach for a VAX and for which something similar will have to be developed for the target machines are shown in table 1. | | | This document describes the Mach sources and provides a basis for estimating both the specific tasks involved in porting Mach to the Mars and Leopard 2 computers and the amount of time it will take. | | | Sub-directories that are not relevant to porting Mach to the Mars and Leopard 2 computers are contained within brackets, "[ ]". |

| | XNU: The Kernel |
| | XNU contains code based on Mach, the legendary architecture that originated as a research project at Carnegie Mellon University in the mid 1980s (Mach itself traces its philosophy to the Accent operating system, also developed at CMU), and has been part of many important systems. | | | The kernel's generic MIB (management information base) is initialized. | | | The I/O Kit includes a modular, layered run-time architecture that presents an abstraction of the underlying hardware by capturing the dynamic relationships between the various hardware/software components (involved in an I/O connection). |

| | For this reason, the interface is not currently available to user-level programs. | | | The External Memory Management Interface (EMMI) is undergoing significant change in the Darwin system. | | | Instead, the BSD filesystem's Universal Buffer Cache (UBC) mechanism should be used. |

| | Is Mach to blame for OS X's slowness? - MacNN Forums |
| | The mach microkernel has nothing to do with the speed of Mac OS X. mach handles very low level I/O stuff and interacts with the hardware on a byte level. | | | A kernel has an effect on the speed of pretty much everything occuring in the computer. | | | I think this applies to most software but not to kernel design. |

| | What's with all these MkLinux Kernels? |
| | MACH KERNEL: Floppy Support on PCI machines ONLY. | | | Added code to attempt to more accurately determine which video hardware is actually being used for the console (compares base address instead of just picking the first one that it finds), which fixes color palette problems for some people. | | | Changes to attempt to reduce problems with mounting write protected floppies read-write (still not quite working like I'd hoped, but the G06 release is behind schedule enough w/o fixing this one completely). |

| | Mach kernel |
| | Mach was a project at the Carnegie-Mellon University that started in 1985 and ended October 1994. | | | While there is still some work being done at CMU, today most development and support on the Mach Kernel is done elsewhere. | | | Additional information about the Mach Kernel can be found at the Mach Project home page. |

| | Welcome to MkLinux.org |
| | MkLinux is a project begun by the OSF Research Institute (now Silicomp RI) and | | | Apple Computer to port Linux, a freely distributed UNIX-like operating system, to a variety of Power Macintosh platforms running on top of OSF Research Institute's implementation of the Mach microkernel. | | | A CD image is also available, and a few users have offered to burn and mail CDs to those people who do not have access to high speed Internet access for a small charge. |
