Im a Unix Technical support 'bod' at the head office of a large chain if
DIY stores, who a year ago or so took over 'Texas' (the chain not state!). 
We have recently aquired from the old stores several RS/6000's running AIX
v3.2.  We have the Boxes themselves and the keys but nothing else.  Because
they have been knocking about for so long it is impossible to find someone
that knows any logons let alone root's.  I understood that I could insert a
bootable disk, smitch the key to service mode and boot, then change roots
passwd  but I have no bootable media.  They are connected to my mini LAN
and when they boot it says TCP daemon and NFS are running.  Is there a way
I could use this to get in!!  I dont know the IP address.  In fact I dont
know a lot about them at all.
Is it possible to login as 'daemon' or some other 'power word'.  I need
help because I have several redundant but perfectly useable boxes.

Thanks, Rob
