This is doubly false.
An MS-DOS partition table can partition at any boundary. Some OSes
(like some versions of MS-DOS) needed track alignment because their boot
loaders did not support crossing track boundaries.
Second, the primary field in the (modern) MS-DOS partition table is an
LBA field. The CHS fields are largely historic and useless because of
the 1024-cylinder limitation, and by only being 24 bits total.
