SRM is the boot monitor - the thing that you type commands to before
the operating system is running.   When it starts up, you'll see that
it actually prints SRM followed by a version number.   Assuming you
have SRM on your Alpha, of course - there's another boot monitor for
booting Windows NT, whose name escapes me at the moment.   If you have
that, then you unfortunately can't boot NetBSD.
