Hey folks, i'm in a real pickle right now. i bought 25 clamshell 466mhz graphite ibooks and whenever i put the HD in and put a disc in the drive to try to install an OS nothing happens, so i pressed the option key and this blue screen with a lock on one side and an arrow on the other, with a space to write in, in the middle. now what i need to know is what should i do? i can put these things together like no one else but when it comes to software i'm lost. i'm going to try to attach the picture of what the screen looks like but i'm not too good at that either. but if someone can get these things up and running i'll give you a complete (no power cord) graphit clamshell for free. basically what i'm trying to say is I NEED HELP ASAP. I made this same post on www.mac-forums.com here: http://www.mac-forums.com/forums/showthread.php?t=38366 I just figured the more people that help the better.
