Well I have a 3770K and I loaded the H3A BIOS and was able to install Snow Leopard with no problems. Then I grabbed Mountain Lion from the store, and tried to make a bootable USB with it using Lion DiskMaker. It appears that the USB was done but the Lion DiskMaker app mentioned something about audio not working, yet when I replugged the USB in it seemed to be fine and I can actually boot off of it. I copied the InstallESD.dmg to the Desktop so I have an extra copy, and then proceeded to "upgrade" using the downloaded installer from the store. It rebooted twice, which seemed normal, and then started the install. After awhile the Apple logo turned to a blocked symbol(a circle with a slash through it) and wouldn't proceed any farther. And now booting into OSX doesn't work at all...
So I figured I would try out the USB I made, and it will not work either but actually gives me a message to try reinstalling.
Do I have to fix the audio with the legacy files before trying to create a USB or is there some other catch? My EVGA 680 Mac card(which is not even installed into the machine yet) says it requires Mountain Lion.
The H3A BIOS is layed out differently(at least the drive booting portion) than the stock F2N BIOS and genuinely feels more unstable. The boot logo disappears long before my 10 second timeout to a black screen. Also, I'm not sure why, but the H3A BIOS doesn't even show the keys to press when booting. At least I remember DEL is the BIOS access, gotta love randomly smashing keys at startup if you don't know them
