Good.

Yes. I assume that video does not work for you? Do you see at least
blinking cursor?

...hmm, problem is that normal video calls really require stack. Very
bad.

You'd have to wrap it with asm("") at least, and need right
constraints.... Hmm, this should be C-equivalent. First try it
somewhere in normal code.

outb(inb(97), 0x80); outb_p(3, 97); outb_p(-74,67); outb_p(-119,66);
outb_p(15,66);

Given that human can only handle about 72 hours without sleep... I'd
say that is bad idea.
