Only problem I can't get it to work. I built from ports and put ISO (and in a second attempt the "bootable" binary) onto a USB with dd(1) but all attempts at booting failed. I also attempted the two methods suggested in the pkg-message it and both failed: 1. at boot prompt (before boot menu) attempting to load it caused a boot loader panic 2. Doing: unload, load /boot/opt/memtest86+ caused a instant reboot -- Aryeh M. Friedman, Lead Developer, http://www.PetiteCloud.org
