For the record: This stuff *can't* be read from the VBIOS and has to be found by trial and error. You also don't have to google the steps, they are described in <a href="show_bug.cgi?id=76490#c48">comment #48</a>. But otherwise you are right, It will limit your card and replacing it with another one seems like the only option you have right now. At least that's what I did too, because I don't see this bug fixed in the near future.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
