[CentOS] Poblem with Centos Logos on X bootup...conversion from whitebox to centos.

Hello all

I migrated my Centos installation from a whitebox install few months
ago. Only one minor issue...on booting up X, the login screen shows
whitebox logos. At that time, I did not tackle it because I assumed that
it will automatically be upgraded with yum...and again it was not
essential to running the OS.

What whitebox rpms do I need to substitute with centos ones to correct
this behaviour?

With regards.
Sanjay.
