Just been on the Asus FTP site...
A few updates posted today for the M4GZ, including a new BIOS (0650) and English PDF manual (E6731)...
BIOS: MaximusIV-GENE-Z-ASUS-0650.zipEnglish PDF Manual: E6731_Maximus_IV_GENE-Z.zipI've not tested the new BIOS (due to have my new M4GZ delivered today :eek: )
Update: M4GZ arrived yesterday - System built with new BIOS - All ok so far (No sleep/wake issues that I had with my previous Sabertooth P67)...
