Anyone out there have any pointers towards documentation
on accessing devices via physical memory? Like, apparently
video memory to write text is mapped at 0xb8000.. do other
devices become mapped like this? Is this documented
information? If so, where? I've read through most of the
intel CPU documentation, but, I havent seen anything related
to this topic. I'd prefer not to use the BIOS in my MBR
code..
