YellowDog install problem
 

Hey guys. I've got an old G4 400mhz laying around and I wanted to try out YellowDog 3.01 on it. Im pretty sure I have that new boot rom ive been readin about, and i "should" be able to simple hold down the C key and boot to the yellowdog install #1 cd. When I boot, i get to the text based yellow dog instal screen, then when I hit enter for a gui setup, the screen goes black... and stays that way. I ve also tried to do it via text install but same problem occurs. any advice on this ? My mac currently has Jagur on it. thanks guys!
