AIX 4.1.3 on 7009-C20 RS/6000

As far as I remember trying to install the client version of AIX on a
server type machine will bomb early in the installation, but it will give
you some confirmation that it did indeed boot from the CD. Maybe your CD is
indeed bad.

Any specific reason why you want to run 4.1.3 and not 4.1.5, 4.2.1 or
4.3.3? (is there any hardware that only works with 4.1.3?).
