- wolfgke 9y ago> Bootloaders are written in real mode. Not when the bootloader is an UEFI application. UEFI puts the processor into 32 bit protected mode or typically long mode (64 bit). So when your bootloader that is implemented as an UEFI application is started, you are already out of real mode.
