Bottomley: Owning your Windows 8 UEFI Platform

That entirely depends on what you mean by 'without EFI'. From my POV, in BIOS mode, my motherboard's EFI is just an implementation detail used by very early boot, of no interest once software I can control is running: among other things, I don't need an EFI partition, an EFI bootloader, or any of the other EFI PE stuff. It might as well be an old-style BIOS from my perspective. (The sensors don't work, but that's got nothing to do with EFI and everything to do with a sensor vendor and motherboard vendor who refuse to release any information on the sensor chip: each refers you to the other for info and neither will give you any).
