Re: Help writing ada booting kernel

Hi Anon,
Thanks for your reply.
I'll try to figure out how to use Import/Export pragma or Ada asm.
I learned Ada when I was still in Uni, one of the course used it, which 
is called concurrent and distributed system. I can use Ada's high level 
features, but I never used its low level power and it's hard to find 
examples on web resources.
