The factory default MEBx password is admin, which you will need to change the first time you log in.
I have a couple of questions that might help us figure out what's going on.
1. Are you using a standard English keyboard layout?
- Using a non standard English keyboard can cause problems, especially when dealing with special characters.
2. Do you have Fast Boot enabled in the BIOS?
- This might be why the MEBx Post is so fast.
