And they can. My system has 4 primary and 4 extended partitions, with
the extended partitions contained in hd3.

The extended partitions _are_ contained in a primary partition, a larger
one that you don't usually see.

hd5 looks like it is associated to hd3, which would contain hd5 && hd6.
Type "dmesg|grep hda" on the command line and see the partitions listed.
The extended partitions are the ones contained between the '<' && '>',
and are contained in the preceeding primary partition.
