Hi Dennis, Good work. I may not speak for everybody on this list, but here are my thoughts:
- From a software engineering standpoint, SharpOS currently has no architecture at all. Mostly things are hacked together to work somehow. I'm not certain if anyone is able to help you. - Some of the devs, who are very concerned about this are just now starting these things in the scope of the MOSA project. (shameless plug: www.mosa-project.org) - It is the goal (at least my understanding) to reuse/adopt MOSA components in order to have a properly architected kernel model. Anyhow to answer your questions: An I/O manager is a central component of any operating system. Some may not explicitly state that though. The I/O manager is responsible for many things, like file system caching and I/O scheduling. So I'd say yes, there are plans to have an I/O manager at some point (independent of its source.) I'm right now finishing off my diploma thesis (HTW Dresden, Computer Science ;)) and hope to spend the freed time to start small working groups for key kernel components soon (again in the MOSA scope.) Hope this helps, Michael > -----Ursprüngliche Nachricht----- > Von: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Im > Auftrag von Dennis Gronewold > Gesendet: Mittwoch, 17.
