 The default boot code
 .El
+.Sh COMPATIBILITY
+Due to the use of 32 bit to store the number of sectors in the MBR,
+.Nm
+can at most use 2^32 - 1 sectors.
+For the prevalent sector size of 512B this means a maximum of 2TB.
+Larger disks should be partitioned using
+.Xr gpt 8 .
+.Pp
+The MBR that
+.Nm
+manipulates, is used by many different OSs, but the exact requirements seems to differ,
+it can be a hassle to get multiple OSs to recognize the same MBR.
+Some OSs will require that slices are located at cylinder boundaries.

 The default boot code will not necessarily handle all slice types
