Hi everyone,
I am suffering from a similar issue. I have a Q77 machine, it's the first time I am using it. When I tried to enter MEBx configuration menu, I tried "admin" and "P@ssw0rd" as default password but it didn't accept. Then I tried removing the CMOS battery but after that I am still stuck in the password. It still doesn't accept "admin" as password. What can I do in this situation? I am really stuck right now.
