Hi,

we have released a new boot cd image, including our new graphical user interface. (www.tabos.org)
It includes most of the common widgets and offers a small amount of applications. This one is alpha, it hasn't been optimized, verified nor documented yet. please give it a try...

and of course: Happy New Year!

Jan

I just tested Tabos under qemu 0.9. There must be some deadlocks because it hangs-up applications randomaly. Next thing is a broken dma support, only pio works fine. As I seen in source you are disabling interrupts very often. Yes, I agree that its the simplest way for synchronization but its not a good sollution. Besides kernel is going to be not preemeptive in that way.

Thanks for testing the image cd. Can you please be more precise which application do lock up? it is not repeatable?
in qemu itself the dma support is broken? that's interesting as it works fine on every system here, including self hosted. and thanks for the notes^

The GUI refuses to load in MS VPC 2007, but text-mode works fine.

Does running the command 'main' from CLI starts the gui?

Nope.

Try "wm". It works for me on VirtualBox. But TabOS is so slow that nothing runs on VirtualBox.

You are using the wrong boot cd image. Use the one linked in the news article..

right...

Now it works fine, but it's still very slow (maybe because it is using the vesa driver). The window's scrollbars don't work.

Is it faster on real computer?
Does it use other gfx drivers, or only vesa driver?

Yes, its repeatable. TraSH is not starting very often and if it starts correctly then after I run some application from trash, it looks like 'stoped' after executing, because command prompt doesnt back to me (i guess traSH is not waked up from semaphore when called application is done).

I updated to the newer disc image and still the same. When trying to load the GUI it hangs at this black screen with a dotted line near the upper-right hand corner.

That happened to me too, but it progressed when I pressed "1". I assume it the selection of the boot-media, but you can't see it since you are in graphics mode.

That's not it for me since I tried going into text mode first and then starting the GUI and I got the same result...

Sooo, any idea?

I have no idea until now. As it is working in qemu and on my real pcs... Maybe something specific with the implementation in virtual pc? as for now i will add it on the todo list, but as nobody owns a windows copy this one hasn't a high priority. but thanks for note anyway
