    So what about hackintosh users? How does this transpose onto us? Any guides yet for a HIS 5770? thanks

    I used the guide from Tonymacx86 site with a Gigabyte HD 5770, works perfectly, QE/CI and dual monitors via dvi all work. Haven’t tested dual monitors with hdmi or d-sub.

    Hi Netkas,
    I badly want to install OSX on my laptop, but there is a mobility 5870 card in it. And this card isnt functional yet on OSX right? On I’ve read that the 5870 mobility is in fact a desktop 5770. Do you think its possible a 5870 mobility can work with desktop 5770 kext’s?

    No. It won’t work. The mobile 5870 may be equivalent in power to a desktop 5770 but it does not use the same drivers. Since no 5xxx series graphics chips are currently used in Apple laptops, there are no mobile drivers. The biggest problem I believe is that the internal link between the graphics card and the built in display is not supported since iMacs use an internal display port connection which laptops do not use.

    netkas, hey , do you have any news at all on the Fermi 400 series nvidia cards,
    anything you can post regarding that and 10.6.4 snow.

    also when do you think the 10.6.5 is coming out, and do you think its going to
    break anyone using multibeast or myhackinstaller?

    what are your thoughts sir!

    thank you, o holy greatness netkas!

    Hi, i’ve bought an Apple Ati Radeon 5770 and i’m using it on a Mac Pro early 2008 (3,1).
    I have some problem when i try to open Final Cut Pro, it says:
    “0 VRAM recognized” and “you need a Quartz Extreme capable video card”. What can i do?

    Приветствую netkas. Уже не знаю где и что искать, сейчас стоит хак на GA-EP45-UD3LR и cartri bios. Купил карточку 5770 (обстоятельства так сложились, что сначала не посмотрел будет ли работать или нет). В общем загвоздка – никак не могу завести ее. Может что подскажешь? Плизз, оч надо

    Nothing unusual, netkas. The DVI doesn’t work because on a PCB there is no TMDS, which is usual have a place on a Mac Edition cards. Read my PM on forum.
