        Surpass 1 TiB disk addressing limit.  Note: there are no plans to handle
        the 2 TiB disk limit in GRUB Legacy, since that would need considerable
        rework.  If you have >2TiB disks, use GRUB 2 instead.

        * grub/asmstub.c (biosdisk): Add unsigned qualifier to `sector'.
        * stage2/bios.c (biosdisk): Likewise.
        * stage2/disk_io.c (rawread, devread, rawwrite, devwrite): Likewise.
        * stage2/shared.h (rawread, devread, rawwrite, devwrite): Likewise.
        * lib/device.c (get_drive_geometry): Replace BLKGETSIZE with
        BLKGETSIZE64.
