I've been doing a ton of hunting and haven't quite come across this predicament. I recently obtained a PowerMac G5 A1047 DP 1.8Ghz. One problem. No hard drive or optical drive. I have multiple hard drives that will work perfectly, but no OS on them. I also have an optical drive, but no IDE cable to plug into the G5's board. Therefore, I cannot find a way to get my Leopard.iso or the DVD installed on the hard drives. I have a USB dock where I can connect the hard drive to my MBP detailed in my signature, but the 2010 MBP cannot boot a Leopard disk. I had the intent of booting from the DVD and installing to the externally connected USB Hard drive. The only (cheapest) solution I can think of is to buy a small IDE cable to hook up the optical drive and install using the Leopard DVD at hand. I'm looking for any other option besides buying the cable. I also have a USB universal drive connector. I hooked up the optical drive I have with that cabling, but the PowerMac G5 will not boot from USB. Found that through research, but I thought I would try anyway. I'm looking for anyone else' thoughts? Comments? I have VMWare Fusion, but I don't believe Fusion will allow me to boot the disk and select another for install, but please correct me if I'm wrong! Thanks.
