ASUS P8P67 Pro Bios Update - Mountain Lion doesn't start!

[Gatsouni]

Hello comrades!

I successfully updated to the latest "3207" version of my ASUS P8P67 Pro Motherboard. Since I had chosen to boot into Apple Disk, the startup procedure sticks on the Apple Logo screen and won't give me access to Mountain Lion. It is frozen there.

Any ideas how should I overcome this problem except from downgrading to older Bios versions?

Thanks a lot!

I have to say that the 3207 version of bios, corrupts the Mac settings and logging into Macintosh is impossible... I simply reverted to older versions of Bios and it worked normal...
