I've installed succesfully Mavericks with niresh 10.9 with this motherboard plus Radeon Hd6570 2GB with an old maxtor 320 Sata. The only problems solved with my experience with ML 10.8.2 is the HDMI Audio using a patched DSDT.AML and selecting the flag PCIROOTUID=1. Total time 30 min. My strange thing is that i've decided to repeat the process with a new disk WesternDigital 1TB Sata3 Green Edition. All the rest is unchanged but after installation without the pendrive used to install Mavericks i'm stuck on Boot0 Error. I tried booting with the niresh pendrive but after the Apple logo my usb keyboard and mouse gone during the creation of account. I don't understand. All the hardware is the same only disk is new. I tried also the Bootdisk utility but with clover the system halt with black screen. I tried USBBUSFIX=YES and nothing happen. Suggestion?
P.S:sorry for my horrible english, i'm italian :-D
