Yes you are correct. Maximum 4 primary or maximum 3 primary and 1
extended which is then sub-divided into more partitions.

When I think I am mounting a M$ DOS partition, am I mounting a real
partition or merely 'the file system' within that partition ?  Some may
think one can't have one without the other.
