How does VERR and VERW handle non-present descriptors? Does it clear the zero flag in that case? Or is it ignored(that would be strange)? Nothing is documented about that.
Edit: The documentation says it to be writable(VERW) or readable(VERR) and that it performs the same checks as loading it into a register and trying a read or write accordingly. So that means the Present(Valid in Bochs) must be accounted for(just not in LSL/LAR)?
