    I need to do a cold restart. I've looked through a lot of docs, and I can't
    seem to find this out. The computer I am working with seems to no longer
    enjoy a warm reboot (like "shutdown -r now" or "reboot") but I'm pretty sure
    it will do cold reboots fine. Is there a port, or is the shutdown command
    hackable for this, or what?

    I remember many computers in bygone years which had this problem. It was
    pretty common back in the 90's it seems like. Computers would reboot and act
    weird using CTRL-ALT-DELETE, but work fine when powered off and on.

    The computer I've got actually fails a memory test during the warm reboot.
    This freezes it. I have to power cycle the machine. And then, the computer
    performs a warm restart, bypassing its memory checks! One more power cycle
    laster, it will boot normally. If I don't do this last reboot, the FreeBSD
    boot loader or the beginning of the kernel boot crashes very early. It's
    stable otherwise on a cold reboot.

    Thanks,
    Billy
