[G4] splash screen

[SE]

A friend bought a computer from a company that covered her computer with 
desktop pictures, start up splash screen, icons with their company name, 
etc. Unbelievable how much "stuff" they put on her computer.

I have removed everything except the splash screen that shows on the 
screen when the OS is loading at start up.

She is running OS 10.2.8

Does anyone know where to find the splash screen file so I can delete it?
