I'm considering Flash updating PC ATI Video AGP cards to MAC versions for use on a G4 533 DA. I currently have an old Rage 128 card from a G3 B&W in the PCI slot but want to upgrade to something better.I have a couple of PC ATI Radeon cards one's a 9000 and the othe isn't clearly marked except for Radeon and the year 2000.I also have some older PC Rage II + DVD and 128 cards, I think one is a PCI and the other AGP.I've never flashed a PC card before and am concerned about damaging the card(s) and/or the G4.I also have an available PC w/AGP slot that I could use. Which platform is easier to Flash off of?
Can I Flash the PC card to the Mac firmware on the PC? What are the risks involved and which approach is the best? I know there are some sites on Flashing out there but I find them a little confusing since I've never done this before.Any help is greatly appreciated. There's a good FAQ at the site Hawaii Cruiser linked to:There's also very good step-by-step instructions included with the ATIFlash utility.It is possible, though unlikely, to destroy your card.
If you haven't backed up your original rom properly, and the flash process is interrupted, you've lost it unless you can find the exact same rom elsewhere.I've successfully flashed two Radeon 7000 cards, and had a third that would not flash. Some manufacturers use different configurations, different size roms, etc. So you really need to know not just that your card is, say, a Radeon 7000 but that it's 32 MB Powercolor Radeon 7000, with Samsung roms and 133/133 core/memory timing.The difference in cost for Mac vs. PC cards had diminished somewhat, so if you're not confident you might want to sell your PC card(s) and buy a Mac card.
I have a Sawtooth G4/500 that I'm looking to upgrade to Quartz Extreme capability.I've been reading the Strangedogs forums, but am now having trouble deciding exactly which card will work for flashing.I'm looking at GeForceFX 5200's because they're cheap and will also support Core Image.I could also use Radeon 7000's and 9200's as well as some older GeForce 2/3 cards.What I'm trying to work out is if those cheap $35 GeForceFX 5200's on NewEgg will flash. There are so many, I don't know which one to get.Any experiences or advice welcome. I actually had to tape pins 11 and 13 on my FX5200 to get it to work on the DA even though it was.supposed. to be fully compatible with AGP 4X slots.You probably mean pins 3 and 11 which you need to do because Apple hijacked unused pins in the AGP 2x specification for use with their ill-fated ADC brainstorm and when AGP 2x came around some of those pins were used and not for what Apple used them for. Sawtooth machines didn't have ADC so don't have to tape, same with G5 machines. Everyone else gets to tape. There's also supposed to be some problem with the AGP port on DA and QS machines that ATI used to explain why their 9600 cards have such a hard time in those machines, something to do with the slot dropping to 33 MHz for some reason but I don't know how true that is.
Originally posted by Luca Rescigno:I flashed a PC Radeon 8500 to Mac. It's possible to do that without even using a PC, by just using an ATI firmware updater. I don't remember how to do it now, but it should turn up pretty quickly through a Google search.The only catch is you need to find a built-by-ATI (no Powercolor, Sapphire, or anything) video card, a full Radeon 8500 (not an LE), with 64 MB of VRAM (not 128 MB).I thought you couldn't use an ATi branded one? The one I flashed for my 'Digital Audio' G4/533 is a Saphire card. The reason you could easily flash that card is 1.
It had the larger EPROM chip that could hold the Mac firmware and 2. ATi released a version of their updater that didn't check to see if the card already had Mac firmware on it. If you find one of those cards I think it can meet all of your requirements except for CI.
(check xlr8yourmac.com to see if they still have the flasher app) My R8500 had a fan but it was pretty quiet. It worked without the fan as well. The fan liked to seize up so every few months I'd have to peel the label back to oil the thing so it'd spin again.

My initial attempt to use the card (witout taping)was actually quite interesting - machine would not even power on. I'm relatively new to upgrading Macs after building PCs for years and that was a bit of a surprise!Must say that it runs great, though.JT. Originally posted by ToolBoy:I flashed a GeForceFX 5200 64bit that I picked up at CompUSA for $59.Had to do the flash on a PC because the version of NVFlash for the Mac didn't recognize the EEPROM on the card.Used version 5.25 on the PC, and it went perfectly.Expose etc is butter smooth at 1600x1200. Everything feels 100% faster.Excellent - not bad for $60, right?And I have always had better luck flashing on a PC - one of the reasons I still keep a stripped PC and old PCI Matrox card in the workshop.JT.
