Hi guys, I'm having a problem with a 333mhz G3 iMac. By trade I am a PC repair technician, I own and operate my own repair shop and hold a CompTIA A+ certification. Someone gave this mac to me, I know it's old, so don't tell me to use it as a doorstop, when I received it it was in working condition running mac os 9.2.1 I think. I cracked it open and installed more RAM, and added more VRAM as well because I had some old AGP ATI 3D Rage cards laying around in a box that were perfect donors. I loaded OSX panther on it and was trying to get the dual booting option (classic & OSX) to run for some reason I thought it would be acceptable to just drag the OS folder from the CDROM onto the root. After I did that, I told it to boot into classic mode. big mistake, now when I turn the mac on, it just displays the old macos logo (two blue guys kissing) and then a question mark and repeats forever I tried to boot from the CDROM by holding down the c key while booting, that does nothing. I tried a MacOS 8 install CD, a 9.2.1 and a panther disc. I know that they were burned properly because I have an old 300mhz mac pro that recognises the disks and even lets me boot from them. I was able to go into openfirmware by slamming a bunch of keys (i have a USB keyboard but it's not designed for apples so I don't have the command key) and reset the nvram and reset defaults and reset all, I also remembered seeing a button next to the CPU when I took the machine apart the first time. so I pulled it apart again and hit that button i think it said cuda on it or something. all of this, and still get nothing. so i figured that maybe the CDROM drive was bad or something -- I've got about 40 dead laptops with DVDroms in them at my shop so I grabbed a couple of those and tried them in that machine as well, and that did nothing. I also have a USB cdrom drive and I can't boot from that either. I have no idea how to zap the pram with a standard keyboard, and I don't even know if this would even help. Other things I've tried were, pulling out the old IDE harddrive and nuking the partitions using a windows PC, hoping that the OF would take the hint and default to booting the cd. What the hell am I doing wrong guys?
