I have a PowerMac 7600/120 with 272MB RAM, and I'm trying to boot off a disc image of YellowDog Linux 3.x, no go. I can boot off a Restore CD, but not the YDL CD. Any ideas?

I have heard of people loading YDL on other PowerMac 7x00 series, just curious what I'm doing wrong. I can't select the CD as the startup drive either. (Mac OS 8.6)
