I wrote the following function in a program last night. I have a couple of
questions, because it compiles fine, but when it's linking, it reports in
the setpal function an 
"undefined reference to red", and gre, and blu. I think it probably has
something to do with the byte registers (ch, dl, dh). I'm not sure, though
-- I'm not fully used to AT&T asm yet.

I'd also like to know how you can rotate the palette quickly.... Any tips
or code would help. (Please reply by e-mail at bottom)

void setpal (int index, byte red, byte gre, byte blu)
{
   asm ("movw $0x1010, %ax
         movw $_index, %bx
         movb $_red, %ch
         movb $_gre, %cl
         movb $_blu, %dh
         int $0x10");
}

Thanks!
