I'm not sure that reason is so obvious... can't imagine why you would need to boot a BIOS, aside from very old software.

- AshamedCaptain 6y agoThe AMD64 architecture is older than UEFI. When it was released, _all_ computers booted using a 16bit BIOS. Even today all desktop computers I know still ship a BIOS compatibility module meaning they still carry a BIOS which includes 16 bits code. All Windows 32-bits (not only supported, but still being sold) require a BIOS. OEMs regularly use FreeDOS for flashing stuff -- which requires a BIOS. Only a couple laptops I've seen as full-fledged UEFI (no CSM) devices. They won't boot 32bit Windows nor anything before Windows 8.
