Hey, i'm new to these forums. I have many macs but right now am having a problem with 2 g3 powermacs. I got these for free from my school. I am trying to put os x on them but i can't get them to boot from cd. I tried clicking the thing on the OSX istall disc and it tells me that it is unable to change startip disc to cd. I tried changing it manually and that didn't work. I also tried to start holding down 'c' to nno avail. I have 2 of these comps and it happens on both. I am thinking this is some sort of administrative thing blocking starting from cd. What should i do?
