I am trying to load a module (a flat binary file) using GRUB2. I have put the file I want to load at the root of the ISO and then modified my grub.cfg to:

Code: Select all

...
  multiboot2 /boot/kernel.bin
  module /test_program.bin
  boot
...

I am then trying to read the information about this module using the multiboot2 crate (my OS is written in Rust) with this code (just to test the number of modules loaded):

Code: Select all

    let boot_info = unsafe { multiboot2::load(multiboot_ptr) };
    println!("Detected {} modules", boot_info.module_tags().count());

This reports that 0 modules have been loaded. I am fairly sure the parsing of the multiboot header is working as intended, as I am using it for page frame allocation etc. successfully. Thanks in advance!

Try "module2" instead of "module" may be.

That works! Thanks very much, albeit at the cost of making me feel a little stupid
