Bit confused about flashing ATI 5770 (PC versio) with zeus

[funkytwig]

Hi. I have a macpro1,1 running Lion and a PC ATI 5770. This works but shows up as a 5000. I wish to flash it partly because I would like the boot screen back and partly because I am trying to get Premiere Pro Mercury Playback Engine working and the hack is not working, I suspect this is due to me having a non flashed PC version.

I have been doing some reading around but the information is a bit fragmented and I am a bit confused. I think I should back up my current ROM (just in case), download an updated rom and flash my card with zeus.

Is this correct. I have the following questions.

1) How do I backup my current rom (and how do I restore if needed)? I have another graphics card in Mac I can connect monitor to.

2) Where do I get the new rom from? Or do I have to make one, if so how?

3) How do I flash the card. On the zeus download page it talks about ATI and Nvida tabs in the application but there are no such Tabs. Under the Flash Tab there is a section with ATI at top. Do I select OS, browse to the rom file and click Flash ATI button?

Regards,
Ben

When you flash a 5770, it will only give a boot screen using an analog VGA connection (the problem is with the port mapping on 3rd-party cards). Only Apple-branded 5770s give you a boot screen on all ports.

Secondly, Premiere's MPE hardware acceleration requires a CUDA card, which ATI/AMD cards are not. You need an NVIDIA card for that.

Cindori can probably explain how the Zeus utility works better, since he's the one who wrote it.

1. Boot windows and dump with GPU-Z

2. Follow guides at netkas.org forums to make your own or try someone elses pre-modded rom

3. Yup
