(The "slow" 350 MHz version hits 0.7 to 2.8 GLOPS.) Note that there were two very different versions of the And with 1-4 gigaflops (billion floating point operations per second) performance at 500 MHz, it's a supercomputer under the pretty plastics. Designed in graphite gray, silver, and clear plastic, it even looks professional.

Offering up to twice the performance of the G3 and three times the power of a Pentium III, the G4 is Apple's first serious pro computer since Steve Jobs became iCEO. Overview "Wicked fast" is the phrase that best summarizes the breakthrough performance of the Power Mac G4 - the first personal computer classified as munitions and under export restriction because of it's power.

There was no code to drive that Hardware in previous versions of Mac OS because that Hardware did not exist when those versions of Mac OS were written. Your Mac has a completely different Hardware Architecture for its Memory and Hard drive. That it will not run older versions of Mac OS is completely unremarkable. And that same IC also provides an Interface for FireWire 800 in certain models, another architectural change. Another new Interface running at speeds never seen before. That same IC also provided a previously unseen Interface to the Hard drive, now at ATA/100 speeds. No support for it exists in any previous version of any Mac OS. The Bus Controller used in previous Macs was replaced with a different High Speed custom Integrated circuit that provided access to a never-before-seen type of memory running faster than ever before. But on the specific Mac you are using, the mirrored drive doors G4, there were major architectural changes. There are plenty of examples where what you want to do would work fine. Again, I know this is a rather stupid question or request, but has anyone ever done this, or if it is remotely possible? I know System 7.6.1 won't work for sure, though there has to be a way to allow the system to recognize by force mac OS's that are lower than what came with the machine?Įven Puma and Cheetah would be interesting to see.

I want to natively boot into Mac OS 8.6 and see what it looks like in full screen and just to see how it runs for nostalgic reasons. So, I have a power mac G4 2003 dual 1.25 MDD model and although I have the original install/restore disks for 10.2(Jaguar) and OS 9.2.2, I was wondering if there is a way, or if it exists, of hacking the firmware to allow my system to boot anything lower than 9.2.2?Īlthough, I got a glimpse of what OS 8.6 and lower looks like through Sheepshaver, I wanted to go a little step further and see if it is remotely possible to FORCE recognize on boot any version of Mac OS other than the ones that came with the machine?
