Yes. I ran Windows 8.1, ran through the 'first time setup' routine, and played around before rebooting and trying to install openSUSE My impression is the Asus 'UEFI' implimentation seems robust, it's 'Bios' settings for configuring the PEK/keys/etc all seem like they know what I'm doing Given the problems went away only when I wiped the whole SSD, I suspect the problem is something to do with the UEFI partition on the hard disk they're shipping.
