RedEagle-OperatingSystem is a hobby Project with the goal to write an operating system for i586+ CPU's.
It is a simple multitasking, singeluser OS working in PM using paging and is made for playing with some lowlevel-stuff.

The operating system is called Adversys since the kernel (reos) reached version 0.10.00 when the bootloader, kernel an applications were separated.
The project consists of the following components:

• bootloader: reosboot
• kernel: reos
• filesystem: FT3fs
• debugging-interfaces: Bifröst, GDB

• REOS @ LowLevel.eu — Last change: 10.12.11
• Mein Blog - Themen: u.a. Betriebssysteme, Programmieren, Mikrokontroller, lowlevel-zeugs, Problemlösungen, Linux — Last change: 25.10.11
• my YouTube-Channel - You'll find some short “reos-booting” - clips there — Last change: 08.12.11
• Twitter darf natürlich auch nicht fehlen
• e-mail: rℯdℯaglℯ.hobby@gmx.nℯt (replace the unicode-ℯ with an ascii-e)

Guest-access to the dokuwiki disabled. I need to be able to embed html-code.
You still can give feedback via twitter, youtube or e-mail: rℯdℯaglℯ.hobby@gmx.nℯt (exchange the unicode-ℯ with an ascii-e)

Shell runs - well, a test-app which tries to read a keystroke , but the key does not arrive at the app. Could be a little problem with the pipes-code… It should be easy to fix.
I had not initialized the process-ID of the kernel, so I could not connect the pipe to the kernel's output. Now, everything works fine
I'll release the code when I'm able to navigate through the nodes of my filesystem.
btw: Does anyone want me to twitter the stuff I'm writing here?

Problem solved - It was a bug in ld ld 2.21.51.0.6-6.fc15 20110118:

   /* LONG((__CTOR_END__ - __CTOR_LIST__) / 4 - 2) */ /* subtraction fails, result was __CTOR_END__ */
    LONG(__CTOR_END__ / 4 - __CTOR_LIST__ / 4 - 2) /* in this case the subtraction works correct again */

I wanted to test the “new” memory-manager in my kernel, but there are lots of problems with the new compiler I got with Fedora 15. After a problem with GAS, my bootloader won't execute the elf-file correctly.
Now I have to look why the GCC 4.6 - elf, or the code itself, does not work any more

That other problen wasn't a bug in the memory-manager, it was an double-free - issue in my test-environment m(
Well, the memory-manager works fine \o/ — next I will continue add an user-interface to the OS, but it will take some time because I have to spend most of my time in an more important project.

I'm too busy for REOS, so there will be no changes during the next months. Studying has a slightly higher priority

New image and source code is available at the download-page.

The “new” name for the whole operating system is Adversys.

So, the current versions of the Adversys 1.0-components:

• kernel: REOS 0.10.00
• bootloader: reosboot 5.3
• filesystem: FT3fs 3.1
• shell: reos - testshell

I uploaded two new Videos on YouTube. (HTML5-version available if you've activated it)

With version 0.10 I'll change the name of the OS. Until now, the kernel IS the operating-system, but usually a kernel is just part of it.

Because the kernel can execute applications I decided to give the OS an other name than the kernel.
So the kernel will still be called ”reos”, but the whole OS with its applications and the reosboot-bootloader gets an other name.

That means: the kernel becomes ”reos 0.10.00”, but the whole OS will be released as version ”$OSNAME 1.0”

btw: secret leak of my todo-list is secret

Bis zur Version 1.0: ▮▮▮▮▮▮▮▯
☑ API
☑ Memorymanager 
☑ Prozessmanager 
☑ Devicemanager 
☑ Dateiverwaltung 
☑ Rechteverwaltung 
☑ Abstraktion 
☐ user-interface

It's a collection of buzzwords I read in several OS-Definitions.

REOS version 0.9.12 (Image & Sourcecode) is available at the download-page.

I uploaded a new video on youtube. (HTML5-version available if you've activated that feature)
You see reos executing 20 threads which are counting

(I'll upload the source-code and an image in a few weeks… (like I say every time , but this time, it's the truth, I promise ))

Well, it was time to switch to a better website for my project. I decided to use a wiki instead of my beautiful self-written 100% HTML-website.
The downloads and the content from the old website will be available during the next days - (12.03.2011..22.03.2011)
