I'm trying to install OS X on my Powermac 7500. I know it's an unsupported install, but I'm still trying. I have had previous versions of OS X running before. My problem is that lately I changed my CD drive to a CD-RW. This causes the OS X cd to not boot. I have no other SCSI cd-rom drives to install in my computer. I thought of moving my hard drive to another computer, but it's raid and can't be moved. Anybody have any suggestion on how to get it installed on this computer?
