black screen in iAtkos L2 with virtualbox on AMD system

5 posts in this topic

Recommended Posts

Hi,

 

I'm receiving a black screen with iAtkos when trying to install Lion (iAtkos L2). My system is running Ubuntu 11.04 Server, and I'm trying to install it in VirtualBox 4.2.0. My hardware setup is as follows:

 

Motherboard: GIGABYTE GA-870A-UD3 AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard

CPU: AMD Phenom II X6 1100T Black Edition Thuban 3.3GHz, 3.7GHz Turbo Socket AM3 125W Six-Core Desktop Processor

Ram: 16GB

HDD: Raid1 setup to mirror two 2tb drives

Graphics: EVGA 512-P3-1300-LR GeForce 8400 GS 512MB 32-bit DDR3 PCI Express 2.0 x16 HDCP Ready Low Profile Video Card

 

When iAtkos boots, I press F8. If I do a regular boot, I get a grey screen with an apple logo. If I try verbose (and with all other flags I found googling this topic), I get a black screen. My hunch on where the problems may lie:

 

- AMD cpu: not so much likely, as I've seen others with successes

- Graphics card

- Raid1 setup for the hard drives

 

This isn't just an iAtkos or a Lion issue. I have snow leopard installed via virtualbox on my ubuntu laptop as well. When I transfered the VDI file (hard disk file) over to my server, I also get a grey screen with apple logo when the VM boots. When I transferred my WinXP VM over, I am able to boot it and use it fine on my server.

 

Please let me know if you know what the problem is. Thanks!

Thanks for your response. I forgot to say that the VDI image I moved from my laptop over had snow leopard running, which gave me a grey screen with apple logo. When I tried to install snow leopard with the nawcom mod cd, the installation process would start, but towards the end, an error would occur (forgot what it was exactly). Something about the stack.

      Hello,
       
      My desktop Hackintosh is running macOS Mojave 10.14.2 with two dedicated GPUs installed: NVIDIA GTX 1080 Ti, AMD Radeon HD 7970.
       
      The AMD GPU is used primarily under macOS and the NVIDIA one under Windows.
       
      macOS boots without issues as long as there are no displays connected to the NVIDIA GPU. If a display is connected then the display connected to the AMD GPU will become blank. The system can be accessed using Screen Sharing/VNC.
       
      There are no problems if I swap PCI-e slots for the GPUs so that the AMD GPU is in the first slot (primary GPU), but I prefer not to do this.
       
      I have tried to remove the whole PCI (bridge) device in the DSDT file and all the lines that refer to it. The PCI entries in ioreg and System Information are gone but System Information still shows an NVIDIA GPU under Graphics/Display.
       
      Many of the suggestions I have found in guides and forum posts do not seem to apply here. My problem with some of the guides and answers is that they give the solution without explaining how anything works, or they tell you what to do without explaining the reasons behind it.
       
      What else can I do? Thank you for any assistance you can provide!
       
      I have attached some files that may help you help me.
       
      DSDT_BIOS_3101.zip contains the original ACPI (*.aml) files without any patches.
      Send me Steffens-iMac.zip is a file produced by RunMe.app, and do contain simple patches to rename some devices.
      DSDT.dsl.patch is a diff of the original DSDT.dsl file and the one with the PCI devices removed (commented out).
       
      Motherboard: ASUS Rampage V Extreme (X99), BIOS version 3101 (macOS does not boot with anything newer).
      Clover version: 4813.

      Hello. My hardware is:
      AMD Athlon X2 7750 dual-core
      Gigabyte NVIDIA 8400GS 512MB ( [VGA] ,HDMI,DVI)
      Motherboard Gigabyte based on NFORCE without AHCI support (only IDE)
      I have successfully installed Mac OS Yosemite, Mavericks and El Capitan with AppleNFORCEATA.kext
      But I can't use it with Mac OS 10.8, don't know why, it just gives error and my internal HDD's are not appearing in Disk Utility.

      I have bought a 2nd hand AMD Radeon 7750 to fix my Mojave installation problems. Although the Vendor/Device Id is in AMD7000Controller.Kext, I get a black screen and with some changes a yellow screen. I can not find any useful information to fix that. All information are for High Sierra and older macOS versions. Is there any fix to resolve that? What if I buy an RX 650 for example?

      Run Vanilla OS X El Capitan, Sierra, High Sierra or Mojave in VirtualBox 5.x.x on a Windows Host
      Following on from my previous guide on how to create a VMware virtual machine running Vanilla OS X El Capitan in Windows, I’ve decided to write a similar guide for creating a VirtualBox El Capitan VM. 
       
      The virtual machine should be useful for testing El Capitan and also for creating installers for use on a real machine/hackintosh.
       
      There are other tutorials and videos on the net about running OS X on Windows machines using pre-made VMDK disk images but you can never guarantee what else is in there….
       
      I’ve gathered info for this guide from several threads in the Multibooting and Virtualisation section of this forum and also the wider internet eg
       
      @colt2 HOW TO: Create a bootable El Capitan ISO for VMware

      VirtualBox Forum: Status of OSX on OSX
       
      Requirements
         Intel PC with four or more CPU cores running Windows 7 X64 or later OS (2 or more cores needed for OS X)    4GB or more RAM (2GB or more will be needed for OS X)    Hard Disk with at least 40GB free for Virtual Machine    Oracle VM VirtualBox v 5.0.34    Install OS X El Capitan app and Mac or Hack to prepare installation iso <-- Now, no longer necessary to have previous access to a Mac or Hack by building the Installer.app from scratch - see post#75    16GB or larger exFAT formatted USB stick to transfer El Capitan iso from Mac/Hack to Host PC  
      Prepare Installation ISO on your Mac or Hack
      1.  On your Mac or Hack, download "Install OS X El Capitan.app" from the App Store into your Applications folder.
      2.  Download and unzip the CECI.tool (attached to this post) into your ~/Downloads folder. The commands in this executable script are shown below for informational purposes.  Note: you will need approx 16GB of free space on your hard disk for the script to complete.
       
       
       
      3.  Open OS X terminal, then run the following commands to execute the script:
      cd downloads chmod +x CECI.tool ./CECI.tool 4.  At the end of the process, you will have an El Capitan iso on your desktop - copy this onto an exFAT formatted USB for use on the PC Host later.
       
       
      Create an El Capitan Virtual Machine in VirtualBox
      1.  Open the VirtualBox program and click the "New" button to create a new VM.
       

       
      2.  Select Mac OS X and Mac OS X 10.11 El Capitan (64 -bit) for Operating System type and version.  I named my Virtual Machine "El_Capitan", then clicked next...
       

       
      3.  Leave the Memory size at the recommended 2048 MB, then click next.
       

       
      4.  Choose to "Create a virtual hard disk now", then click the create button.
       

       
      5.  For the hard disk file type, the default is VDI (VirtualBox Disk Image) but I have selected VMDK for inter-operability with VMWare.  Click next...
       

       
      6.  For Storage on physical hard disk, I have chosen the default Dynamically allocated (grows larger to a set limit as you need more disk space).
       

       
      7.  On the File location and size screen, you can set the location of the new virtual hard disk and its size - I recommend changing disk size to 40GB or larger.  When you click the create button, you will now see your new VM in the VirtualBox main GUI.
       

       
      8.  Click the settings button on the Main Menu to tweak a few settings....
         a.  On the System/Motherboard tab in Boot Order, you can uncheck the Floppy Drive (who has these now?)
       

       
         b.  On the System/Processor tab, you can increase the allocated CPU cores to 2
       

       
         c.  On the Display tab, you can increase the allocated Video Memory to 128MB
       

       
         d.  On the Storage tab, click on the icon of the Optical Drive and select "Choose Virtual Optical Disk File". 
       

       
      Navigate and select the El Capitan ISO we created earlier...
       

       
         e.  Click the OK button to finalise the VM settings.
       
       
      Patch El Capitan vbox configuration file with DMI Settings from a Mac
      1.  From the start menu, type cmd and click run as administrator to open an administrative command prompt. 
       

       
      2.  Choose a Mac Model similar to your host system, then type the following lines, followed by <enter>  after each line.  Make sure you first close all VirtualBox Windows and the VirtualBox program, otherwise any changes you make won't stick...

      To spoof Lynnfield i5 750 CPU
      VBoxManage.exe modifyvm "El_Capitan" --cpuidset 00000001 000106e5 06100800 0098e3fd bfebfbff To spoof IvyBridge CPU
      VBoxManage.exe modifyvm "El_Capitan" --cpuidset 00000001 000306a9 04100800 7fbae3ff bfebfbff or
      VBoxManage.exe modifyvm "El_Capitan" --cpuidset 00000001 000306a9 00020800 80000201 178bfbff 4.  Close the command prompt window.
       
       
      Installation of El Capitan
      We are now ready to start the El_Capitan Virtual Machine....
       



       
      Installation should be relatively straight forward, just following the prompts of the OS X installer:
      1.  Select language, agree to legal terms
       

       
      2.  Use Disk Utility from the Utilities Menu to erase and format the virtual hard drive as a single partition GUID Mac OS X Extended.  I named my drive "Macintosh HD" but you can enter whatever you like eg El_Capitan.
       

       
      3.  Quit DU and choose Macintosh HD to install El Capitan on.
      4.  After 20-30 min (depending on how fast your system is), the installation will complete.  At this point, unmount the El Capitan ISO by clicking the Devices menu from the VM window, click Optical Drives, then choose Remove disk from virtual drive.  The VM is now ready to reboot into OS X from the virtual hard drive.
      5.  At the welcome screen, choose your country and keyboard layout.  You can skip transfer information, location services and logging in with your Apple ID if you wish…
      6.  Create a User Account and select your Time Zone.  You can skip sending diagnostics and usage data to Apple….
      7.  Finally, you will arrive at the El Capitan Desktop.
       

       
      8.  Network/internet and audio should work OOB but on my system, the sounds were distorted.  Unfortunately, there is no QE/CI and the VM resolution will be fixed without the ability to dynamically resize the VM window (no VirtualBox additions for OS X guests atm). 
       
       
      Customization with VBoxManage
      1.  You can change the default resolution of 1024*768 (after shutting down the VM) with the VBoxManage command from the Windows Administrative Command Prompt:
      cd "C:\Program Files\Oracle\VirtualBox\" VBoxManage setextradata "El_Capitan" VBoxInternal2/EfiGopMode N (Where N can be one of 0,1,2,3,4,5) referring to the 640x480, 800x600, 1024x768, 1280x1024, 1440x900, 1920x1200 screen resolution respectively.
       
      Update:  For VirtualBox 5.2.x, the command for changing screen resolution has changed...
       
      VBoxManage setextradata "<MyVM>" VBoxInternal2/EfiGraphicsResolution XxY (where X=Horizontal screen resolution, Y=Vertical screen resolution)
      eg
      VBoxManage setextradata "<MyVM>" VBoxInternal2/EfiGraphicsResolution 1280x1024 2.  Adding serials and other SMBIOS details for the System Information Screen
      VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemSerial" "W8#######B6" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiBoardSerial" "W8#########1A" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemVendor" "Apple Inc." VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiSystemFamily" "iMac" VBoxManage setextradata "El_Capitan" "VBoxInternal/Devices/efi/0/Config/DmiBIOSVersion" "IM112.0057.03B" A listing of known issues with Mac OS X guests can be found in the VirtualBox Manual - link https://www.virtualbox.org/manual/ch14.html.
       
      Vanilla Mavericks and Yosemite, Snow Leopard from Retail DVD
      The same VM settings for El Capitan will also boot and run vanilla installations of OS X Mavericks and Yosemite .  Attached to this post are installer scripts to create bootable Mavericks (CMI.tool) and Yosemite (CYI.tool) ISOs for VirtualBox and VMware.
       
      With the respective OS X installer apps in the Applications folder, download and run the installer tools using terminal ie
       
      To create a Mavericks ISO on your desktop
      cd downloads chmod +x CMI.tool ./CMI.tool To create a Yosemite ISO on your desktop
      cd downloads chmod +x CYI.tool ./CYI.tool Here is a screenshot of the VM running Mavericks 10.9.5...
       

       
      Finally, those without a Mac/Hack to prepare the install media can purchase a retail Snow Leopard DVD directly from Apple and install OSX 10.6.3 on their virtual machines (Snow Leopard, Lion and Mountain Lion run quite happily in VirtualBox with 1 CPU, 1-2 GB of RAM and the rest of the settings unchanged from above).  Once you update by combo update to SL 10.6.8, you can directly download El Capitan from the App Store for free .
       

       
      UPDATE macOS Sierra 10.12 to 10.12.6: For macOS Sierra, use CSI.tool in post#51.
      UPDATE macOS High Sierra 17A365:  For macOS High Sierra, use CHSI.tool in post#73.
      UPDATE macOS Mojave 18A391:  For macOS Mojave or High Sierra, use macOS_iso_creator.tool on page 4 of thread.
       
      Good luck and enjoy
