platforms/i386: report Pentium Pro as minimum supported x86 processor
As of FreeBSD 13.0[1] we default to i686 for 32-bit x86, and the
compiler will make use of the CMOV instruction.
It is still possible to compile FreeBSD/i386 for i486 or i586, but the
release artifacts are i686 and we don't regularly build or test i486 or
i586, and it may well be broken.

== Introduction
-This page contains information about the FreeBSD/i386 platform. FreeBSD/i386 should support any CPU compatible with the Intel(T) 80486 or better in 32-bit mode, although almost every recent AMD(T) and Intel(T) CPU will also be capable of running in 64-bit mode using the link:../amd64/[FreeBSD/amd64] port.
+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 link:../amd64/[FreeBSD/amd64] port instead.
FreeBSD/i386 supports up to 4GiB of RAM by default. Machines with more RAM will either need to run link:../amd64/[FreeBSD/amd64] or run with link:{faq}#memory-i386-over-4gb[Physical Address Extension (PAE)] enabled in order to make use of any memory above the 4GiB boundary.
