Install WebSphere Portal - Express Plus

[Guy Terry <guy.terry@xxxxxxxxxxxxxxxxxxx>]

This came 'free' with our 520 Enterprise server, and I'm working through 
a redbook called 'WebSphere Portal Express and Express Plus V5 for the 
IBM Eserver iSeries Server' (is this the best place to find installation 
instructions?)
One of the prerequisites is '5722WS5 - WebSphere Application Server 
V5.0', but I can't figure out which of the CD's that I got with our i5 
it might be on so I can install it.
Likely candidates include:

WebSphere Application Server - Express. One version 5.0 and the other 
version 5.1. According to the licence book for each, these are
IBM Web Enablement for iSeries (5722-WE1) and
IBM WebSphere Application Server - Express, Version 5.0 for iSeries 
(5722-IWE).


WebSphere Application Server - Express Version 6.0. These apparently are
IBM Web Enablement for i5/OS (5722-WE2) and
IBM WebSphere Application Server - Express v 6.0 (5724-I63)



IBM Enterprise Edition Installation Assistant (5733-ED1) - actually, 
what the hell is this?


Can someone point me in the right direction?
