I couldn't find a list that tells whether all A7N266-VM's support 137GB+ readily, or whether some older BIOS' didn't support, or which versions of BIOS do support it. I don't want to flash the BIOS if it's not necessary (I cannot do it, I'd have to give instructions and help my brother do it, so I don't want to take any risks). Any help in this regard will be highly appreciated.
