I have a PowerMac G3 Blue & White with 128Mb RAM running Mac OS 8.6 I want to upgrade to OS X (10.4). It has an internal CDROM drive, but I have the DVD version of the OS. I have an external DVD drive (Sony DRX-830UL-T). I thought I read somewhere I could attach the drive via the Firewire connections, reboot while holding the Option key down, and the Mac would recognize the drive. So far, no good. Any suggestions? Thanks in advance.
