Inside the multiboot information structure, the
color_type color_info bytes seem to be offset by 2 bytes.
I would expect values of {16,8,8,8,0,8}, but those bytes are found at 112 (0x70), instead of 110 (0x6E) as stated in the docs.
Here is a memory dump of the multiboot information structure:
I created my iso with the commmand 'grub-mkrescue -o os.iso .tmp'
I tested it using 'qemu-system-i386 -cdrom os.iso'
This is my multiboot header:
I'm using grub version 2.06-2, and qemu version 6.2.0.
