Help, I have just installed and booted 1.6 beta (first time BSD
install), but I can't log in.

From install.txt:

::  2.   Logging in
::
::       After reboot, you can log in as root at the login prompt. Unless
::       you've set a password in sysinst, there is no initial password.

This appears not to be true - I have no recollection of setting a
password in sysinst, but any attempt to login to root with a blank
password is greeted with 'Login incorrect'

So near and yet so far . . .

Can anyone state what the default password really is, or how to login
otherwise?
