to do to assign space to FreeBSD on your disk(s). This is done through
the "sysinstall" program, which lives on the inital boot floppy. Those

Modern hard disk drives are now getting big enough that people don't want
to allocate all of one to just one operating system anymore, especially
given the increasing size of disk drives (the latest 9.0 Gbyte models holding
the equivalent of some six thousand 1.44MB floppies!) and the virtual
explosion of operating system options available for the PC. To solve this
problem, IBM came up with a scheme for "slicing" the disks into more manageble
chunks, or partitions. It works, but only just. To better understand
why, first a brief bit of history:
