Oops, i meant SkyOS is closed source.

What would you call part of the software which loads in the apps, choose what threads should be ran and how long. controls what app is drawing to screen. manages the filesystem and manages ram and such?

Usually one would call that the operating system. If you want to steal one instead of develop one, get off our boards.

The kernel/OS... Maybe you should considering reading the OSDev wiki..

mgdt:

I think that it is best for you to download ReactOS binaries, modify the boot screens, etc. and fire up some C programming language for Windows or Delphi and make your own EXPLORER.EXE shell with your programs (OS accessories, games, etc). You will be running on a reverse-engineered NT kernel, but it's better than nothing.

Or take Linux and make some new graphical shell or something, you know what I'm talking about; because

I was wondering if anyone has written or know where to get an OS that has a lot of basic stuff completed.

is your task to do, if you want to be a OS programmer.

My boot loader which is 99% in real mode do this using visa.

other stuff are sequential processes just put plan. decide priorities for these tasks.

That's nice..
User (with webpages and documents open): *opens program*
Computer: "This is a full screen program that will only run in 1024x768. Please change your resolution"
User: "mmkay" *changse resolution*
Computer: "Now rebooting.." *closes all unsaved documents*

I'm really interested in this "protested mode" and using "visa" in real mode..

Seriously... This is just the funniest thread I've seen yet

I am looking for an OS that can already boot up, initialize the gfx to a 16 or 32bit resolution (preferably 1024x786), keyboard+mouse and perhaps sound. File IO to the HD, USB, floopy or w/e would be nice too.

I heard grub can boot up and init the gfx to the resolution i want. If thats true there are several of you who has an os i want? If it helps i have an intel mac mini. I heard EFI is nice so maybe a lot of hard work is done in that case?

Getting back to the topic, you could have a look at Windows XP Embedded. It's basically a compontentised version of Windows. You select what you want to include (kernel of course, then optional things; Win32 App support, GDI, Explorer, Command Prompt, Internet Explorer, Media Player). What I'm getting at is you could use Windows XP Embedded, include the default kernel and some drivers, and then write your own shell!

I contacted the guy who is doing newos and i am considering XP Embedded. Those two options look like the best options for me.

Thanks everyone for you help!

I seriously doubt it would be legal to distribute this "XP Embedded".. Not to mention the fact if you build upon something closed source, You can't fix or tweak anything to your own needs.

just curious...What language do you program in?
Also, are you sure your not just wanting to make a shell of your own? Whenever I first wanted to make an OS, actually all I wanted to make was a shell, but of course, then I got interested with the ease of use of the BIOS and made a 16bit OS, then scrapped that, made 32bit OS, got to floppy drives, and gave up..(OT a bit but anyway...)

I'd actually prefer using visa in unreal protested mode where you don't have to pay the bill if you think it's unfair.

Why not? You just need a license from Microsoft.

Windows CE Core license: $3
Windows CE Professional license: $16
Windows Embedded license: $90

These are both per unit costs.. It also says free for non commercial use

I'll say this, It's nothing but: "C-O-M-M-E-R-C-I-A-L G-A-R-B-A-G-E!!"

Lack of source and and freedom, Not to mention a disgusting design..

If I was you, I'd try to write a desktop environment for Linux, and make a new distribution...

Haha you guys are confusing me again.

Brynet-Inc: I dont mind not being able to tweak something. Chances are it is *decent* if MS is selling it and it is not for home users and it doesnt have a lot of their componates

hckr83: I think i do want to write a shell but i have to go a bit father then that. I like to use a custom filesystem natively which is current a WIP. And i'd like control of which process can be opened, scheduling, permissions and other things. I am afraid if i make a windows shell it still will be butchered by the based it is standing on.

I program in C and C++. I have written maybe 1/8 of a compiler (well, code generator) so i can write better code with keywords that are not in C/C++ and remove legal C/C++ stuff.

MessiahAndrw: free for non commercial use is good

Steve the Pirate: I don't like some of the things linux does. I plan to have a different style of using permissions. I dont like sudo, if i took that out wouldnt basing it on linux be useful (as many things wont work or everyone has super user access?)

One of the alternatives i was thinking is just writing a few libs to emulate what i want done for me and have it running on windows, linux and mac (most likely using SDL) and make it easy for people to use. If ppl like it enough i'd have motivation to kill the crap underneath and make the OS.
