pub struct Header {
    pub header_start: u32,
    // some fields omitted
}

Multiboot struct bootloaders mainly interact with

Fields

Implementations

impl Header

pub fn from_slice(buffer: &[u8]) -> Option<Self>

Get the header by parsing it from a slice.

The needed portion of the slice is copied.

pub fn wants_modules_page_aligned(&self) -> bool

If true, then the modules have to be page aligned.

pub fn wants_memory_information(&self) -> bool

If true, memory information must be passed.

pub fn has_video_mode(&self) -> bool

If true, then the mode_type, width, height and depth fields are valid and video information has to be passed.

pub fn has_multiboot_addresses(&self) -> bool

If true, then the header_addr, load_addr, load_end_addr, bss_end_addr and entry_addr fields are valid and must be used to load the kernel.

pub fn get_addresses(&self) -> Option<MultibootAddresses>

Get the load addresses specified in the Multiboot header.

If this function returns None the binary has to be loaded as an ELF instead.

pub fn get_preferred_video_mode(&self) -> Option<MultibootVideoMode>

Get the preferred video mode specified in the Multiboot header.
