If your machine is already running DOS and has little or no free
space available for FreeBSD's installation, all is not lost! You
may find the ``FIPS'' utility, provided in the
tools/ subdirectory on the FreeBSD CDROM or on the
various FreeBSD ftp sites, to be quite useful.
FIPS allows you to split an existing DOS partition into two
pieces, preserving the original partition and allowing you to
install onto the second free piece. You first ``defrag'' your
DOS partition, using the DOS 6.xx DEFRAG utility or the
Norton Disk tools, then run FIPS. It will prompt you for
the rest of the information it needs. Afterwards, you can reboot
and install FreeBSD on the new free slice. See the Distributions
menu for an estimation of how much free space you'll need for the
kind of installation you want.
