What is the largest partition size supported by native DOS running FAT16?

EXPLANATION

Due to the mathematical limitations of FAT16, without an overlay file or special driver the largest partition size is 2GB.The limit on partition size was dictated by the 8-bit signed count of
sectors per cluster, which originally had a maximum power-of-two value of 64. With the standard hard disk sector size of 512 bytes, this gives a maximum of 32 KiB cluster size, thereby fixing the "definitive" limit for the FAT16 partition size at 2 GiB for sector size 512.
