    Just wondering if this can be done on Mac Pro 4.1 version?

  2. Cindori 10 years ago

    All the intel Mac Pros.

    There is no additional power connector for the card in the DVD casing. The only connector there are the eSATA connector that combine power and eSATA for the additional DVD player. Doe you need to have the card connected to power when you do the flashing? If not then it would solve my problem.

  4. Tenchu 10 years ago

    Basically, my Mac Pro does not have a Molex connector in the spare DVD compartment.

    By the way, great guide and programming.

    Tenchu, as the guide states, only the 2008, 2007 and 2006 Mac Pros have a molex power cord in the DVD section. The 2009 has an eSata.

    I’ve read reports of succesful flash with no extra power, but no promises. If not possible, Zeus will give you a message that flash aborted. ๐Ÿ™‚

    Cool, thanks for the info. I will give it a shot ๐Ÿ™‚

    After reading through the forum again, it’s my understanding that if I install natit in my SL 10.6.2 I should be able to boot into unflashed PC card and flash it with Zeus and then uninstall natit from the system, since I can hook PC 4890 directly to my mac’s motherboard with the existing power cables. Also, do you think I can run Parallel and boot into Windowz and dump the original ROM that way or do I have to boot into boot camp to dump it (which mean I have to go thru the step in setting that up.)

    I have purchased this video card XFX HD-489X-ZSFC which I believe is one of the card that was know to work. Do I use the ROM files that was included in your download package or do I have to use the one from, #13?

    Again, thanks in advance for you help. I did try to look thru the post for like a few hours but was not able to find the answer for the ROM part :(. Don’t want to waste $200 in the process of doing this ๐Ÿ™‚

    Hi. If you have your old video card, why not just run the display from that. And 4890 in slot 2. That way you dont need Natit. Which does not work for all cards anyway.

    Read the guide again and especially the piece about Revisions.
    I can not tell what rom might be compatible unless you provide me with that.

  9. Tenchu 10 years ago

    OK. The only problem is my old card is ATI 4870, unless you can select the card with Zeus. My understanding is that you should not have 2 ATI card in the mac unless it’s only with the old ATI flasher. Also I have the 2009 early Mac Pro 4,1 which does not have the right power connectors for powering another video card. I might try the desktop sharing method and see If I can get it to flash that way.

    I will check the retail box once it arrive to see what revision it is. I will upload the ROM when I get my card if I can’t get it to work. Again sorry about asking so many questions.

    Please read what I write.

    “Iโ€™ve read reports of succesful flash with no extra power, but no promises. If not possible, Zeus will give you a message that flash aborted.”

    So use power on your 4870 but not on the 4890.

    From Zeus Feature List:

    “Safer Flashing
    The biggest problem with ATI Flashing Tool was that you had to remove other ATI cards to prevent them from being flashed too. This is fixed in Zeus. Now, only cards compatible with the ROM should be flashed. This means that you do no longer have to install injectors and crap if youโ€™re upgrading from the x1900 or other ATI Cards.”

    Hello, can we use this software with a PowerMac G5 for flash a video card AGP with a card PCI?
    Thank you…

  12. Cindori 10 years ago

    Intel Macs only, sorry.
