Asmadian 0.01 alpha

I have just released the first version of the Asmadian microkernel. It is a VERY new OS, I need developers/helpers/testers.
There are still no drivers - the system cannot even load programs from disk (although there is a fork(), there is no exec() because system() and exit() can be used instead).
I think there might be giant bugs and misconceptions. Please test!!! If you can, write drivers, or give links to specififcation. Please ask if you want to become an admin on sourcefrge.net

You might want to test first next time. Bochs should not break your OS with a default configuration.

hmm, i tested it on qemu both with and without kvm, then i tested it on virtualbox and it works on all of them. why would it not work on bochs??

Because qemu and virtualbox are based off the same codebase? It's like upgrading the processor revision while keeping the motherboard and equipment mostly the same.
Bochs is in comparison a different project.
