Reformatting problem with OS X Mac

Hi

I am running a G4 desktop 330Mhz machine and trying the upgrade from 9.2.2 to 10.2?

I have run the install but now when the machine tries to boot up, it will only get as far as the apple sign in the centre of the screen and then it freezes and the screen has horizontal lines across it (like interference on a TV).

I want to be able to install the OS X disk and reformat the hard drive.

Help please!

It sounds like you forgot to perform a firmware upgrade before installing OS X.
Older Macs usually require a firmware upgrade (must be done from OS 9)
for OS X to function properly.
