Grub Module

[artrecks]

Does Grub load modules in the memory or the module names are just passed to the kernel??
If it loads the modules in the memory, what memory position does it use?

GRUB loads the modules into memory, and then it passes you the locations via the multiboot header (mods_addr field).

Example:

Code: Select all

	// the module list
	module_t* mods = (module_t*) MultiBootHeader->mods_addr;
	
	// temporary ELF relocation class
	ELFRelocation tmpreloc;

	// loop through and load each module
	for( int i = 0; i < MultiBootHeader->mods_count; i++ )
	{
		// load it, and execute it
		tmpreloc.LoadFile( mods[i].mod_start );
		tmpreloc.RelocateExecutable();
	}

Is there any way to choose where the modules are loaded?

I don't believe there is - I'm afraid you have to relocate them yourself.
