All RS/6000's I have seen work fine with generic svga pc monitors.
(it uses sync on green).  You may need a physical adaptor to make the 
connection (if it's a 13W3).

Serial console should work, but you may need to hit an 'F' key to
select it.

The readout tells you which step in POST/os boot it is currently in.
That way if it stops or fails you can look up where it failed.
Upon completion of boot (or some point in os boot) the display 
clears.
