What's the prompt? The NetBSD/alpha faq does give some basic info
on SRM usage, if that's where you are...and it is programmable for
action on power up. (``>>>set auto_action boot'', IIRC)

I'm a bit confused here, but with respect to the 1.4 address, we always
use the higher load address now, because we are able to use non-contiguous
physical memory segments and as a result it doesn't waste any space.
