You can boot from an AIX install CD and go into maintenance mode and change
the root password - as in just about all *NIXs.

Run "diag" from the root account once you're in and discover what's installed
in your system. (IBM typically used SE HDD in RS/6000). Then go to IBM's
website, locate the sales manual for your RS/6000 (they have them going back
for many years) and use the FRUs you discovered in "diag" to find the
specifications of the FRUs in the Sale Manual.
