OpenBSD dropped support for the 80386 around 2005, and the 80486 sometime later. The arch name i386 doesn't actually mean 386.

- vikingerik 4y agoRight. In this context, i386 really means the 32-bit x86 architecture, as opposed to 64-bit. I don't know of any architectural differences that would require a Pentium over a 386 or 486 (besides a FPU.) The Pentium runs the same software in the same memory and address space, just faster. Unless something requires Pentium MMX or SSE instructions.
- kimixa 4y agoThings like CMOV were introduced in the pentium pro (i686), which often is the cut-off for reasonably modern OS support.
