How do I do a COLD Reboot on FreeBSD?

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.
