FreeBSD The Power to Serve

FreeBSD/i386 Project


This page contains information about the FreeBSD/i386 platform. FreeBSD/i386 should support any CPU compatible with the Intel Pentium Pro / Pentium II (i686) or better. Contemporary AMD and Intel CPUs should run in 64-bit mode using the FreeBSD/amd64 port instead.

FreeBSD/i386 supports up to 4GiB of RAM by default. Machines with more RAM will either need to run FreeBSD/amd64 or run with Physical Address Extension (PAE) enabled in order to make use of any memory above the 4GiB boundary.


FreeBSD/i386 runs in 32-bit multiuser mode, in both Uniprocessor and Multiprocessor mode.

The i386 platform is a Tier 2 platform in FreeBSD 13.0 and later.
