+Disk partition sizes and offsets are in sector (most likely 512 bytes) units.
+You may set these size/offset pairs on cylinder boundaries 
+     (the number of sector per cylinder is given in )
+     (the `sectors/cylinder' entry, which is not shown here)
+Also, you *must* make sure that the 'i' partition points at the MSDOS
+partition that will be used for booting. The 'c' partition shall start
+at offset 0 and include the entire disk. This is most likely correct when
+you see the default label in the editor.
+
+Do not change any parameters except the partition layout and the label name.
