Have you tried ln -s aj /etc/malloc.conf, or something like this. It is in the archives under current if you search for it. $ sysctl -da | grep machdep.dis machdep.disable_rtc_set: machdep.disable_mtrrs: Disable i686 MTRRs. <<==very bad for performance, most likely here because of some bad cyrix options you have. Those are for a 586(I think 586) class cpu
