no i didn't use any boot flags during unibeast installation or post installation, below is my bios setting, under multi beast setting - i used easy beast install, system utilities, hank's appleintelE1000e ethernet. I can't get the onboard sound working, i just use a cheap usb audio with C-media chipset. only cost me 25.00 HKD. Hope someone will make a dsdt for this mobo.
