I'm booting just fine on an old BIOS system from a pair (mdraid 1) of 3
TB GPT disks.
The MBR compatibility on GPT disks allow the old machine to boot from a
GPT disk
and load GRUB. Then GRUB takes over and loads the kernel and the kernel
has
no problems understanding GPT disks.
The boot disks must have an EFI boot partition even though it's not used
in this case.
