<para>FreeBSD 2.1.7 was the last version of FreeBSD that
could be installed on a 4MB system. FreeBSD 2.2 and later
needs at least 5MB, and &os; 5.X and later need at least 8MB to
install on a new system.</para>

<para>All versions of FreeBSD prior to 5.X will <emphasis>run</emphasis>
in 4MB of RAM, they just cannot run the installation
program in 4MB. You can add extra memory for the install
process, if you like, and then after the system is up and
running, go back to 4MB. Or you could swap your disk into
a system which has &gt;4MB, install onto the disk and then
process, and then revert to 4MB after the system is
running. Or you could move your disk into
a system which has sufficient memory, install onto the disk and then
swap it back.</para>
<para>After the installation, if you build a custom kernel,
it will run in 4 MB. Someone has even successfully booted
with 2 MB, although the system was almost unusable.</para>
