To be honest, if you even *thought* that such things could be done, you don't have anything /approaching/ the level of knowledge to even attempt to do it. One instance out of hundreds: what do you think the code in a system's ROM *does*? What is it actually there for? The code in a computer's firmware is there to initialise the hardware in the system, test it and then bring it to a known state, then load an operating system from storage and start it running. This means that you can't simply take the ROMs out of one machine and put them in another, because the code will not work on hardware other than that which it is designed for. To give a facetiously trivial example, if the Mac firmware expects the graphics card's framebuffer to be located at &86F0000 in the memory map, and it doesn't find the framebuffer there, it will fail. There is little to no resemblance between the hardware of a PS3 and that of a Mac G5. Porting the OS from one to the other would be a massive undertaking involving many man-years of effort. But even setting aside all this, you seem to believe that the Cell processor is faster than the G5. It isn't. Cell is a very specialised tool and not a terribly good fit for a videogame console, for starters. It's not a very fast PowerPC. It's not PowerPC at all; it's merely a relative. It couples a PowerPC-like core with a bunch of very simple, very specialised sub-processors called SPs. These are not PowerPCs; they are very much simpler than that and can only run certain simple specialised tasks. They cannot run PowerPC code. Cell can be very capable for certain types of task where the calculation can be split up into 6-8 little chunks which can run in parallel on the SPs. Most ordinary computer code cannot, though. You can think of Cell as being a little like one fairly low-powered chip, similar to a PowerPC, coupled with a tiny computer grid of half a dozen ARM processors, which can be used to accelerate a few specific tasks such as MP3 coding, movie transcoding and stuff like that - and *nothing else*. For general purposes, they are useless. -- Liam Proven • Profile: http://www.linkedin.com/in/liamproven Email: [email protected] • GMail/GoogleTalk/Orkut: [email protected] Tel: +44 20-8685-0498 • Cell: +44 7939-087884 • Fax: + 44 870-9151419 AOL/AIM/iChat/Yahoo/Skype: liamproven • LiveJournal/Twitter: lproven MSN: [email protected] • ICQ: 73187508 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
