Sorry for my stupid question, but is the kernel an elf-bin? I think no, but
maybe I'm wrong.
For the userland: yes they are all elf-bin, but I don't know for the kernel.
I don't know if we have to link it or we can use only the "assemby" code.

Without assember we can do nothing. Maybe without linker we can do the kernel.
Right?
But if we don't try we'll never know! 8)

We need as many tools as possible....

Try to remember! Eat fishes, if this can help! 8)))

So the question is: what is exactly a toolchain???

On the installation manual. It said something like "you need an assembler to
build it" or something like that. If it can be useful I can post (or send) the
Install file of gcc2.8 so you can read it without download the pack. Does
someone want it?

Me too 8(
Hey you! Yes you reading this message! Do you want to donate your Ultra? No?!?
Ok I tried! 8)

Me too. But with the simulator we cannot simulate everything. For example
there's no OBP....
And I have searche for V9 simulator. Nothing 8(

Wow! Lucky man! 8)
But remember: we have many tester. Yes, it's not the same thing, but better
than nothing. So if you want to try your code you can ask someone to do it for
you... ;)

I think it's not a prob. But we need a more "open" room on the internet.
Someone offered this, so I will contact him asking to let us use that room ;)
