Hello,
For my current OS, I have spent a fair amount of time planning its design. Its design is described in the image attached

I think it should be fairly self explanatory, NDS data provider is async I/O model that I am designing
Please comment on the design
Thanks,
nexos

I think your design is very reasonable and very thorough.
Only critique I have: Can the GUI manager be outside of the subsystems? Should it perhaps better be _under_ the subsystems (and partially in the subsystems)?

Greetings

The GUI is in theory under the subsystems. I planned on having each subsystem abstract there own interface on top of the GUI manager (i.e., have POSIX create an X compatibility layer). The only reason it isn't actually there is because I didn't have enough room on the image .

OK! Then from my point of view the design is perfect.

Thanks! I've spent the past few moths muddling through books on Unix design, Windows design, and looking at things on the net, and this was my result .
