The branch main has been updated by emaste: URL: https://cgit.FreeBSD.org/doc/commit/?id=b8a18fbe082c738e4e9e70d8c6b62c69bf8ab2c5 commit b8a18fbe082c738e4e9e70d8c6b62c69bf8ab2c5 Author: Ed Maste <[email protected]> AuthorDate: 2024-06-25 19:19:01 +0000 Commit: Ed Maste <[email protected]> CommitDate: 2024-06-25 23:59:32 +0000 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.

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.
