    Syslinux 4 supports it with full 64-bit capabilities. SeaBIOS (used in
    Qemu/KVM) supports it, and I know at least some hardware/firmware RAID
    solutions support it; I recently got access to a 3 TB SATA drive but due
    to NDA requirements I can't reveal the results of that testing.

    I work for Intel. I don't speak on their behalf.
