Almost 1 year after version 0.1, I present version 0.3.5. The first version of my operating system that can load and run a single program from the disk which is 100% seperate from the kernel.



A full list of what is new:

• A real physical memory manager (bitmap based).
• Faster floppy disk driver.
• Moved the shell code out of the kernel.
• New system calls including, file system calls (open, close, read, write), userspace memory interface, file navigation (finddir, readdir), power management (shutdown, reboot), CPU info, Sleep, MEM info, Time info.
• OS specific toolchain.
• ELF loading.
• Fully featured keyboard support (in the shell).
• Improved high resolution text mode font.

I'm specifically looking for testing on computers with a real floppy disk (don't have access to one at the moment) or a real PC speaker (be warned, it is supposed to beep when it starts up). However, any testing, real hardware or emulator, is highly appreciated.

Congrats! No time to test unfortunately...

I have tested it, and it is a good piece of work. Keep on going.


Bugs: -Everytime i press Caps lock the system halts and i have to reboot (Virtual PC and VirtualBox)
-After restart everything the system crashes(VirtualBox)
-After restart the system holds(Virtual PC)
-when i shutdown i get a 3 o.O (Virtual PC)
-no cursor (Virtual PC)
-Floppy Controller timeout (Bochs)

Things to change: -The Music^^. Its nice but use more of the high tones, they are better in my opinion.

Thanks for testing! I don't have access to Virtual PC (I develop in Linux) so I can only address the issues with VirtualBox.

The first one is confirmed in VirtualBox. The second I was only able to reproduce once. I had several problems like the second one when I tested on real hardware but I fixed all of them before the release.

The error codes come from my realmode APM driver. A 3 means that it was able to initiate power management on all of the devices but it failed to turn them off. I have tested this driver on a real computer which supports APM and it does work if the computer supports it. Maybe I should document the error codes somewhere?

I can't reproduce that one. I regularly test in bochs so I'm wondering, which version are you using?

Maybe I'll move them up an octave. I just don't want it to become annoying.

EDIT:
The first two should now be fixed in SVN. Incidentally, both were due to race conditions. I also moved the music up by one octave.
