Well, I started my OS project over a few weeks ago, it isn't the most impressive OS (I think Brueggi's is much better, partly because of the fox lady...) but it works
Top line in white text displays some CPU fetures and whats enabled:
bit 0: This bit shows that you have CPUID.
bit 1: This bit shows that your CPU supports PAE paging, and is enabled instead of legacy.
bit 2: This will show APIC suport, but right now I just jump over it and enable PIC...

The yellow text on the topline, displays wheather you have a compatible FDD or not (Mira only supports 1.44MB diskettes). 1 = yes, 0 = no

The cyan/blue text under the purple line is a dump of your Hard disk info obtained with the "Identify" command, right now I only check the MASTER...

Doesn't look much like a human-readable language!

I do not understand what you mean.



Frankly, neither does my code But it's just kernel initialization DEBUG until I get to the point were I start using C++. (right now it's all in ASM...)

I was referring to the contents of the screenshot. Frankly, the screenshot rather gives me a feeling of Kernel Crash.

May be some more readable phrases would be better?

Doesn't matter much anyway. Never Mind.

You missed my star trek reference Mr Data (The one in the picture I posted) is an android

Quite actually it basically could be considered a kernel crash as it stops execution directly after DEBUG is displayed... I'll probably get to more readable phrases latter, right now the goal is just to get things working

Well, here's mine. Might not look to different to the last screenshot I posted, but that version string tells the difference ARMv7 port

A simple shell. Nothing special. Except that the whole system is written in C#.

There were several minutes of prolonged maniacal laughter when this finally worked.



edit: fixed image link

Reposting jnc100's image link, for people with modern browsers that are blocking it due to the certificate.

Lightening strike in the background? Happened with me too only.. the power went out..

Hi,

I'm very new to OSDev and real OS development. I say 'real' because I have played with the code from the Xinu book before (back in the DOS days). However, it has been something I have wanted to try for decades. Finding this site was the motivation I needed. I have also played with databases and compilers. I guess I aim high....

So, for a couple of weekends of work, I have managed to:

• Create a Bootstrap

• Have the bootstrap load a 2 sector bootloader

• Jump to the loaded code (different segment than the bootstrap)

• Enable A20 (thank for the sample code)

• Read the usable memory map (again, thanks for the help)

• Display the memory map on the screen

• Halt the processor

Qemu must have been equipped with the SeaBIOS for quite a long time. I've been using a version that uses the Plex86 BIOS, never bothered to try a new one as long as the older one is working. I'm kinda traditionalist.

Anway, you got something to work. Go on!

Carbon calculating PI in a worker thread created using pthreads. No point actually in creating a thread to directly join on it, but well, it works.

Is this a new idea or will I run into patent problems? Mouse-cursor clock (4:37):-

[Edit: no, it turns out it isn't a new idea - I've just found a few via Google, though most don't show any images. One that is shown is a JavaScript clock that slowly follows the cursor around and hovers near it if it stays still for long enough, while another blocks the view of whatever the cursor's over, replacing it with a silly great clock face. My idea was initially for a large circular cursor which wouldn't need very accurate alignment to click on buttons, just so long as they're in the circle and nearer to the center than any other buttons. I then thought of adding the clock idea into it because I didn't want to dedicate a corner of the screen to a clock in the way that Windows does.]

You will run into patent problems with anything you write, or rather you won't.. unless you make some impact on the market. Which you won't.

Hey guys! Never posted on here before! I figured now would be a good time. I recently rewrote my kernel from scratch (-_-) because of some bad design ideas, and because I had followed tutorials so closely, that I wanted to do it myself. And I did! (well for the most part... I needed references from time to time ) well now that I rewrote, it's now a higher half (mapped at 0xC0000000). I've just got multitasking up and running (something that was plaguing me before, was easier once I fixed a few thing ), and am currently working on a VFS so I can load executables from my initrd There's some background, and here is a image, just a little test of my kernel heap, and a message to show my console driver


EDIT: I just realized I typed "forums.osdev.org" instead of "forum.osdev.org" hahaha whoops xP
