Here's how that works...

The drive's "master boot record" has a small bit of code in there,  and the
main partition table,  which has exactly four entries.  You can use any of
these four entries for primary partitions,  which includes any bootable
partition,  dos,  winxx,  OS/2,  or Boot Manager.  Only one of these is
supposed to be flagged as "active" (although apparently Linux doesn't have a
problem if more than one is) and that's the one that will boot,  while the
others won't be seen once the system is booted.

One of those four entries can be an "extended partition",  which can support
any number of "drives" or "logical drives" or "logical partitions" -- the way
they do that is that successive table entries are stored at other places on
the disk,  so the four-entry table really isn't a limit.

There's a shareware partition-resizer program out there,  the copy I have here 
is presz120.zip,  which has an *excellent* doc file that explains all of this
in detail,  if you want to know more about it.
