Hi all, Well, I am a university student in the second year with a reasonable knowledge in C and would like to help in anyway the FreeBSD project, specially acpi. I don't know much about it at all but could be a nice opportunity to learn about things which I always liked, starting with small stuff, of course, and help the community. So, would be nice to know your opinion about it, if it sounds reasonable/possible, anything... Thanks :) Bye. Sorta, but not really. > > PCI is a tree structure.
