They can do more effecient file system search. They can do more effecient memory management. Well because they can write the subsystems from scratch, in a manner that isnt prone to memory leaks or corruption. ReactOS needs to get this OS out soon and start working on a 64 bit version as well as the ability to take advantage of multi-processors or it will die a quick death.įrom what I read from their site the long term plans will include expanding its OS beyond Win32 eventually create its own identity. In theory, Apples transitions to an all 64 bit OS should be smoother. Leopard is suppose to bring 64 bit to the User. Apple has been running 64 bit “under the hood” so to speak in Tiger. I personally believe Vista’s ability to run all 64 bit apps smoothly won’t happen until the first service pack is out. Microsoft just screw up the 64 bit transition. Linux has had 64 bit version for years but still seems to be an after thought in their community rather than mainstream. This is both the OS’s fault and the developers. In ReactOS defense, 64 bit is having a slow start among the other operating systems. Still stuck in a 32 bit world they better have this OS up and running by 2009 max and already have a 64 bit version on its way. The only negative side I really see is that these guys are way behind the times. Should make ReactOS easier and faster to patch and make it more secure than Win2000/XP ever was. Theoritcally, an app that requires wine (like a game) should run better and be more stable on ReactOS than on Linux running wine. Since their kernel is suppose to run win32 apps natively ReactOS version of wine will be probably will be a lot smaller than Linux and be used for things like DirectX compatibility. This probably helps speed up the development. ReactOS has taken wine and ported over to their kernel. Some people have tried to make a case that ReactOS is just a self running wine. Everything else, all the underlying stuff, would be different. If you get my point, The type FPS = OS and the Basic out lying theme (Human vs Alien) = Win32 apps. For instance, there are a lot of FPSs and none of them are not clones but have many similarities (example how many human vs alien FPSs are there or how about War FPSs). They have there own kernel that just so happens to be designed to be able to run win32 apps natively. Microsoft can’t touch them because ReactOS is not a clone. Of course it isn’t going to run like full blown XP with 2 major updates. Like people have commented as well as ReactOS themselves have said its in an early Alpha stage. But has shown massive improvements which is a good point. Note: This project is still in Alpha state. And second, this release is aimed to be run mostly in virtualizers / emulators (like QEmu, VMWare, Parallels, etc): because of the big amount of changes, our development team was not able to test/fix all problems which arise when running ReactOS on real hardware. First of all, please don’t forget this is an alpha-stage operating system, which means it is not suitable to replace your main OS (due to stability and compatibility concerns). However, there are a few things worth mentioning. Read through the changelog, and you will see the amount of changes in this release! Boot video driver (and a splash screen) was added.More fixes in the Win32 subsystem and user-mode DLLs.Registry-support has been greatly improved thanks to addition of “cmlib”, a library shared by the boot loader and the kernel to handle binary registry hives it even supports binary registry hives created by Windows.Bugs were fixed in kernel-mode drivers and a better USB driver was added.Run-time library (Rtl) got a lot of improvements and bugfixes.The Kernel experienced a massive rewrite of incompatible parts (and is still in the process of improvement).HAL’s key areas have been significantly improved (irql-related, bus support, kd-functions).It’s very hard to sum up the huge Changelog in an outline, but briefly: ReactOS 0.3.1 Mainly, the work focused on rewriting certain parts of the ReactOS Core (kernel, HAL, bootloader, etc). ReactOS is a free and open-sourced operating system based on the Windows architecture, providing support for existing applications and drivers, and an alternative to the current dominant consumer operating system.
