===== Reference boot.ini =====
This is the reference **boot.ini** to customize the boot configuration instead of default. You can just download it and copy into VFAT partition of your MicroSD/eMMC, it will be affected on next boot immediately. Not like Hardkernel's Ubuntu release, this **boot.ini** does not require **uImage** and **meson8b_odroidc.dtd**. This will read such files from the booting card directly.
