>We haven't ever supported SMP on i486, to my knowledge. There were never any usable i486 SMP hardware. The i486 CPU was not designed to do SMP so getting two CPUs to talk together (IPIs and all that) required a lot of glue-logic, which never got chip-ified. A few prototypes were built, but nothing ever reached production, least of all HP's 1000xi486 chip "mainfram" project. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
