FC3-re1115.0-ppc-disc2-ftp.iso
FC3-re1115.0-ppc-disc3-ftp.iso
FC3-re1115.0-ppc-disc4-ftp.iso

My configuration:
700mHz

I installed it with:

What's going on?

I installed Fedora successfully in linux text mode. When I do 14. 
everything is ok. 15. too but when I try to do 18. with yabootconfig 
shell tells me that there's no such file or something (action?).. I 
rebooted but eMac boots to Mac OS X.. help me.. I wnat to use Fedora..
