+Fortunately there is a bootloader standard: the [Multiboot
+Specification][multiboot]. So our kernel just needs to indicate that it supports
+Multiboot and every Multiboot-compliant bootloader can boot it. We will use the [GRUB 2] bootloader together with the [Multiboot 2] specification. So let's begin!
+
+To indicate our Multiboot 2 support to the bootloader, our kernel must contain a *Multiboot Header*, which has the following format:
+
+Field | Size in byte
+------|-----
+magic number | 4
+
+Offset | Type | Field Name
+-------|------|-----------
+0      | u32  | magic
+4      | u32  | architecture
+8      | u32  | header_length
+12     | u32  | checksum
+16-XX  |      | tags
