    There is no native QE CI support for the 6850 in the "Snow Leo DVD" distro that I'm using I have installed kext files from this location from HERE At this point the graphics card is recognized, and I am able to change resolutions to 1920x1080x32 without the "Graphics Mode" flag However, QE is not supported, and it doesn't recognize that it's a "6850" under the "About Mac" info it's listed as some weird NL45 adapter I have read that there is native support from a special 10.6.7 update HERE SPECS: Motherboard: Asus Sabertooth 990FX CPU: Phenom II X4 960T RAM: Samsung MV-3V4G3D/US GPU: Visiontek 6850 1GB PSU: ANTEC 620 NEO ECO HDD: Samsung SSD 840 PRO 128 GB Distro: SnowLeoDVD Kernel: 10.6.3 legacy kernel from HERE OSX: 10.6.2 (Currently) BootFlags: maxmem=4096 busratio=15 I have attempted about 6 different ways of trying to boot my PC to mac os 1. iatkos v7 <-- very unstable only gained access by using 1 core at arch=i386 2. iatkos v3 <-- unable to start setup 3. niresh 12495 <--- unable to start OS 4. niresh 12496 fixed kext <--- unable to start setup 5. nawcom ModCD+Retail snow Leo <--- unable to start setup I have mac up and running very well with SNOWLEODVD, at this point I just need help with QE CI Thanks
  4. Background After searching though an abundance of forums to get through many errors and graphics problems, I have been able to put together 2 very successful AMD 10.6.8 computers. The process is very easy, and should work on any AMD computer. System Specs: ASUS M4A79 Deluxe AMD Phenom II X3 720(2.8Ghz) Overclocked to 3.4GhzX4 G.SKILL PI Black 4GB (2 x 2GB) DDR2 800 (PC2 6400) HIS AMD 6850 GPU Before you install Download my Zip from rapidshare Unzip Burn The mod CD to a disk Go out and "buy" a copy of 10.6.3 or 10.6.4 Reboot and go into bios Make sure the drive you are installing to is set to AHCI Turn off Cool N' Quiet Turn off C1E Install Boot from that Mod CD that you burned earlier Wait till it shows the nawcom chameleon screen, insert the 10.6.3 or 10.6.4 disk and press F5 When the install DVD pops up type in "GraphicsEnabler=No" and hit enter This should bring you to the install screen, if you have a problem, leave a comment below When you get to the install screen keep hitting next till you get to destination select and then open Disk Utility In Disk Utility, select the HDD you want to install to and then go to erase and name it what you want to. After you have erased it, it will show up in destinations, select it and hit next when you get to the last screen, hit Customize and deselect Graphics Enabler Click Install If all went well, it should bring you to the setup screen were you enter all your info(dont worry if the graphics look weird, that will be fixed when we update to 10.6.8) Go through everything, and then transfer the folder from the zip on to the mac desktop Updateing to 10.6.8 to give you the app store and full graphics support Download and install the 10.6.8 combo update http://support.apple.com/kb/DL1399 (DO NOT CLICK RESTART!!!) With the 10.6.8 window still open, go into the folder from the zip Open up the legacy kernel package and finish installing that Open [url=&quot;http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/&quot;]#####[/url] and install the IOUSBFamily Rollback and System utilities ONLY Once that is complete, go in the Kexts folder, and open up Kext Wizard In Kext Wizard, go to the Installation tab, find and select the 2 kexts in kexts folder, click the System/Library/Extensions button, and click install Once completed, go into Maintenance click on the System/Library/Extensions button, and then click Execute After it is done(it takes a while), close Kext Wizard [*]Go back to the combo update window, and click restart Your Done!

  6. Hi all, I'm a first-time Hackintosher. Tried a few years back but I couldn't get it to work. Thought I'd give it a go again now that I've a few more years of experience on me. To start, here are my specs... Asus P8H61-M Mainboard Intel Core i72600K @3.5Ghz Asus EAH6850 2GB 1TB Samsung HD103SJ 8GB 1333Mhz DDR3 RAM What I've done so far... - Installed OS X Mavericks on a 100Gb partition using a ##### USB created in OS X Mountain Lion running on a Windows Machine in VMWare Workstation. - Run ##### (##### configuration). - Got wireless networking up and running, using a Sweex Lwo53 USB wlan receiver, and drivers from RalinkTech/MediaTech website. At the moment, however, I am only able to boot into safe mode. The problem seems to lie with the GPU and its kexts somewhere, as when I disable either AMD6000Controller.kext or AMDX3000.kext, the system boots just fine, but without any hardware acceleration. I've spent about a week googling the topic, and found plenty of leads, but nothing's worked. I've experimented with most of the more common bootflags, but I don't quite understand DSDT whether its necessary when using Mavericks. I also don't quite understand framebuffers and personalities with regards to my GPU. I've been a hardcore Windows user all my life so I'm very much out of my depth. I'm also not one for posting on forums much, but this community seems brilliant, so I figure someone must be able to point me in the right direction! Any help would be greatly appreciated. If anyone needs any more info, just let me know. (Also, I am aware that this site/forum does not support tonymacx86, so I don't know whether I'm allowed to mention his programmes or not, but those were the first thing I came across and they seemed the most simple at the time, so apologies in advance for that.) Cheers!
  7. I have had a great deal of success with Clover on a GA-Z77X-UP4 TH board with a discrete GA AMD HD 6850 GPU. Once the OS is up it is running very well. As far as I understand I'm in full UEFI mode. But I'm wondering if this is causing issues during booting because my 6850 is not (?) UEFI compliant (doesn't have the GOP or whatever)? I'm having issues with booting. The symptoms I'm seeing: 1. if I have two monitors plugged into the 6850 (dvi and displayport), I get the Clover "console menu" (or whatever it's called?) rather than the usual GUI menu, and if I continue the boot, the monitor attached to the displayport output only shows output in a very small section of the screen in the upper left corner, with lots of artifacts. Note that this is not the whole screen squished, it's just the upper left corner - I can see the normal Apple icon in the upper left corner, and I can type in my password, log in, and interact with the Apple menu normally. But 85% of the screen is black and what I can see, artifacts terribly. 2. if I have just my older (non thunderbolt) monitor plugged into a DVI output on the 6850, system boots fine - normal Clover GUI, normal desktop, I can then plug in my thunderbolt monitor to the displayport output and it's fine. What is that Clover console menu? It seems to be a symptom of Clover crashing or not loading properly. I have made lots of trials in the BIOS, enabling/disabling the onboard GPU, changing boot order, changing "init display" settings, turning off rapidstart, disabling full screen logo, and so on. There is no combination of BIOS settings that allows me to boot cold with both monitors plugged in and see the normal Clover GUI and get to the OS properly. Interestingly, I can't remember if I've EVER seen a POST on this board - where you see the BIOS version, the type of CPU, RAM, SATA devices, etc. Not even with just a DVI into the onboard GPU. In the boot options, I see, in addition to UEFI options for my SSD and HD (I have Yosemite bootable on both), a mystery third option labelled "Mac OS X". I have no idea what this is. Does anyone know or have a clue what this option is or where it came from? I've considered but haven't tried connecting the thunderbolt monitor using an adapter to one of the other outputs on the GPU. Most recently I've tried enabling onboard GPU, plugging a THIRD monitor into onboard DVI, plugging usual monitors into 6850 DVI and displayport, and booting. This displays normal Clover GUI to onboard DVI output, and black screens to 6850 outputs; and eventually the 6850 outputs come on and everything looks good. But then I noticed that the mouse seems to "stutter" if I look at it closely. I swear interacting with the OS in this configuration introduces a lagginess that is hard to quantify. Anyone have any thoughts? I'm on the latest "stable" BIOS for this board. FYI I would recommend everyone stay away from this board. For this reason and wonky USB support. I got it because I thought thunderbolt was the future, but it's just not worth it.
  8. Tarjeta gráfica AMD Radeon 6850 de 1Gb en Mac OS X Lion Se trata del modelo Asus EAH6850 Direct CU que tiene 1Gb de memoria DDR5. Es una tarjeta de gama media con potencia suficiente para no echar de menos a los modelos más caros en la gran mayoría de las tareas. Es bastante silenciosa. Su identificador es 0×67391002 y está incluido en extensiones como ATI6000Controller.kext y ATIRadeonX3000.kext: Fabricante: ATI (0×1002) ID del dispositivo: 0×6739. Se puede usar en Lion con excelente rendimiento pero con algunas limitaciones que se comentarán en este texto junto con métodos diferentes de instalación. Es importante remarcar que esta tarjeta viene con 4 puertos, 2 DVI (uno puramente digital y otro con salida analógica para poder conectar convertidores DVI-VGA en caso necesario), 1 HDMI y 1 DisplayPort (DP en adelante), DVI 1 será el analógico y DVI 2 el digital (DVI 2 es el que está separado de los otros 3 que forman una misma línea): [---] [-------] [DVI2] [DP] [HDMI] [DVI1] No he conseguido que DVI 2 funcione de ninguna manera, el monitor se apaga como cuando entra en modo de ahorro de energía. DVI 1 funciona siempre, independientemente del método de instalación utilizado. Los otros 2 puertos funcionan de forma variable según los casos. Instalación sin DSDT La forma más simple de instalar esta tarjeta es colocándola sin más y arrancando el PC, en mi sistema (placa Gigabyte P55-USB3) arranca y funciona con buenas resoluciones pero sin aceleración gráfica completa (se puede comprobar arrancando DVD Player o Chess que fallan y no llegan a iniciarse). Esta modalidad equivale a tener en el archivo org.chameleon.boot.plist (o.c.b.p en adelante) el modificador Graphics Enabler (GE en adelante) = No, de forma que Chameleon no carga datos para la tarjeta. En Perfil de Sistema aparece mal reconocida, se muestra como AMD Radeon 6xxx. Solamente funciona el puerto DVI 1. Pero si en vez de GE=No ponemos GE=Yes en o.c.b.p la tarjeta arranca con aceleración gráfica completa (DVD Player arranca bien) y se muestra correctamente en Perfil de Sistema como AMD Radeon 6850. Funcionan los puertos DVI 1 y DP. Los chips gráficos AMD (ATI) utilizan distintos framebuffers dependiendo del chip, el framebuffer nativo del chip 6850 parece ser Duckweed. Con GE=No se utiliza el framebuffer genérico de ATI que se llama Radeon, no proporciona aceleración gráfica completa. Con GE=Yes se utiliza Duckweed. Se puede averiguar el framebuffer utilizado con el comando ioreg | grep ATY en Terminal, se obtiene una salida similar a ésta: | +-o ATY,Duckweed@0 <class AtiFbStub, id 0x1000002f8, registered, matched, active | +-o ATY,Duckweed@1 <class AtiFbStub, id 0x1000002f9, registered, matched, active | +-o ATY,Duckweed@2 <class AtiFbStub, id 0x1000002fa, registered, matched, active | +-o ATY,Duckweed@3 <class AtiFbStub, id 0x1000002fb, registered, matched, active Desde o.c.b.p se puede configurar qué framebuffer utilizar con el modificador AtiConfig en la clave Kernel Flags, suele acompañarse del modificador AtiPorts que indica el nº de puertos de la tarjeta gráfica, 4 en este caso. Por ejemplo, forzando la utilización del framebuffer Bulrushes: <key>Kernel Flags</key> <string>AtiConfig=Bulrushes AtiPorts=4</string> se consigue que funcionen 3 puertos, todos menos DVI 2, pero se observa el fallo ya comentado con DVD Player y además paradas y retrardos del ratón. Estos framebuffers a veces se llaman personalidades (personalities) en archivos de configuración y en los Info.plist. Como resumen, si usas GE=Yes y te conformas con 2 puertos (DVI 1 y DP) la tarjeta gráfica funciona muy bien en Lion. Puedes realizar pruebas con los modificadores AtiConfig y AtiPorts porque algunos usuarios con modelos diferentes de placa base han conseguido resultados distintos a los míos. Instalación con DSDT También es posible inyectar datos del chip gráfico desde el archivo DSDT.aml. En las pruebas que yo he realizado no he obtenido todavía la situación ideal de aceleración gráfica completa y los 4 puertos funcionantes, pero sí se consiguen resultados interesantes como cambiar el nombre de la tarjeta en Perfil de Sistema o conseguir buena aceleración con GE=No. Puedes leer sobre inyección de código gráfico en DSDT en ####### y en InsanelyMac entre otros sitios. He probado un código propuesto por iFabio (ahora Fabio2203) con el que se obtiene: tarjeta bien reconocida en Perfil de Sistema aceleración gráfica sin necesidad de usar GE=Yes 2 puertos funcionantes: DVI 1 y DP. El código se añade en el dispositivo PCI0, en mi DSDT se añade un dispositivo PEGP dentro de PCI0, PEGP ha de tener correcta la dirección de memoria en que está la tarjeta gráfica, la línea Name (_ADR, 0×00030000), normalmente es 0×00030000 (en mi caso) o 0×00010000 (en otras placas), se puede ver con el programa de Apple llamado Ioregistry Explorer aunque esa referencia de memoria no es sencilla de localizar: También he probado otro código propuesto por Juanerson, va colocado en el mismo sitio del DSDT, con este código la tarjeta funciona bien pero necesita GE=Yes en o.c.b.p tarjeta bien reconocida en Perfil de Sistema aceleración gráfica solamente si se usa GE=Yes 2 puertos funcionantes: DVI 1 y DP: Resumen El puerto DVI 1 es el único que funciona en todas las circunstancias. El puerto DVI 2 no ha funcionado con ningún método. Con GE=Yes hay aceleración, funcionan DVI 1 y DP. Con GE=No falta aceleración, funcionan DVI 1 y DP. El DSDT de Fabio2203 no necesita GE=Yes para tener aceleración, funcionan DVI 1 y DP. El DSDT de Juanerson necesita GE=Yes para tener aceleración, funcionan DVI 1 y DP. La única forma de que funcione el puerto HDMI es cambiando al framebuffer Bulrushes pero hay fallos con paradas y retardos del ratón y falta aceleración. Algunos usuarios han comentado que utilizando Bulrushes junto con el DSDT de Fabio2203 se consigue HDMI sin fallos del ratón. Nota: para usuarios expertos con ganas de trabajar en profundidad existe una guía desarrollada por Alexander Martinez, se trata de un texto muy profesional con un enorme trabajo detrás pero excesivamente complejo para la mayoría de los usuarios.
