Hello. I'm implementing video part of multiboot specification. Currently the only defined interface is for providing VBE info. I propose following way to set fields if video is non VBE: vbe_control_info=0xffffffff When vbe_control_info is set to 0xffffffff all VBE-specific fields are invalid vbe_mode set to 0xffff vbe_interface_seg=0xffff vbe_interface_off=0xffff vbe_interface_len=0xff vbe_mode_info points to structure similar to vbe_mode_info but with all vbe-specific fields set to zero. Remaining (valid) fields are (full structur is in include/grub/i386/pc/vbe.h)
