Have a PowerMac G5 here at work that now flashes that wonderful blinking folder icon upon powering up. Seems to have lost its way to the operating system. The person before me did a wonderful job of not leaving behind any documentation regarding it... So now I'm stuck at square one with not much to go off of. Have tried all the discs in my office, that are all for Mac OS X (Mac Computers, etc, startup discs), and I keep getting the error that "Mac OS X cannot be installed on this computer". Lovely, right? It's an older model, I'm guessing before Mac started having Intel-based processors. Anyone know online where I can, maybe, download an appropriate startup disc, or if there's any way I can get to another startup screen?
