 ### Booting on Real Hardware
 
 To boot on real hardware, write either the `uefi.img` or the `bios.img` disk image to an USB thumb drive.

 In the [previous post], we learned how to make our minimal kernel bootable.
 Using the [`BootInfo`] provided by the bootloader, we were able to access a special memory region called the _[framebuffer]_, which controls the screen output.
