We should be glad that this community is growing internationally, vincelawrence is still under age but he seeks knowledge so forgive his foolish attempts

Edit:
Testing Multitasking Terminals for openBOX OS under QEMU

RED indicates inactive window while GREEN indicates active one.

The Circular shaped cursor indicates if the terminal is still operating the executed command or not. Still not sure if i should call it multitasking terminals since there are 2 terminals, its actually running on a single kernel with OS layering method instead of emulating

By the way, I am glad to be back!

Clearly he's a member of the distant Philippino branch of the Rurikid dynasty.

I am half Ukrainian and Filipino, was that bad?

Well, my explanation is more interesting and if true would be cooler. You should go with that and claim your rightful throne as King of the Rus.

I get it Now can we please go back to work

Yes, my liege.

I just started my OS few weeks ago and is in stage of setting idt and gdt and not more than that. Can't take any input from kbd or handle irqs.

Hey guys, I just got back into things about two weeks ago. I'm on my 3rd rewrite of my kernel so far, and this one is by far the best. Now that I understand everything better, it all seems to click together easier. I know this is no where near a lot of you all's OS's, but I'm feeling good about it. It might look very similar to some of my old stuff, but if you were to see the code, it is SO MUCH nicer. Haha

Most recently added feature: Fully functioning VFS with driver interface, and automatic directory caching. The file system is implemented in the standard unix way (everything mounted under root or '/'). I've also written a TAR file system driver which will load and read a tar file from a boot module.

I think I've just about finished up the VFS code (for now ), and will soon move on to multitasking. This when things start to get complicated, so wish me luck!

I've been gone for a while, but thanks for all the support before now! I could never have made it this far without you guys.

Everyone shows off flashy pics of fancy graphics that don't really show much of the underlying os... so I thought I'd show off both!

This is a screenshot of OmniSpeak (a Commander Keen 5 reimplimentation) running on my OS.
And it shows off the LVM code, FAT mounting and VTerm autoscaling all in one!

Umm... This may sound stupid: How are you able to run graphics in text mode?

My guess is... he's running text in graphics mode, not graphics in text mode .

Indeed. Besides, you actually can use the VGA hardware to draw in alphanumeric modes. One technique is to regenerate glyphs. The resolutions range from 320x200 to 720x400, depending on the mode).

It's not a huge change, but I'm pretty excited about it. I've got multitasking working correctly. (even on real hardware) I can put parameters and return addresses on the stack for the new process (I have a task_return function which exits the task upon return from the function), join a currently running process (I need to add a timeout option for the join function), and I've just written a simple spin lock implementation to control accesses to the screen (I was getting weird results as two processes tried to scroll ).

Now that I have multitasking and a VFS interface, I think I will try to start loading drivers! I'm pretty stoked.



Edit:

Just tested it out, and I can also pass parameters to tasks. This is rather simple, but I just realized I hadn't tested it (I just pass spawn_task an array, and copy that array to the stack after the return address, of course changing ESP also )

That's quite a lot of work. Anticipating future images
