[G4] Trying to insall Panther on a Yikes G4

[Darin Sheriff]

I recently acquired a Yikes G4 with 256mb of system memory and a 10gb hard 
drive.  I am trying to install OS X Panther on it but I get as far as a grey 
screen with the Apple logo on it.  The monitor then goes to sleep (and stays 
that way) and I have no idea what is happening after this.

The video card is an ATI Rage 128 with 16mb of memory and I recently 
purchased the 256mb memory module from Microcenter that the mac guys there 
recommended.  What am I missing?
