Is it possible to create a UEFI BIOS image with a legacy, generic VGA BIOS embedded inside? I would think not since that VGA BIOS would rely on DOS INT calls and contain legacy 16-bit code which won't run in any UEFI BIOS? Or, to somehow imbed GRUB4DOS-UEFI with a legacy VGABIOS module and link the code to it instead of VGA BIOS calls in the system (CSM) BIOS module?
