Glad to see this thread, I've been thinking of upgrading hardware on my machine, but I think I'm going to hold off another year or so and just upgrade my current box to Mavericks. Almost identical system specs to the original post.
Edit: Never mind, I got it to boot, but I had to do GraphicsEnabler=Yes and PCIRootUID=1, so completely the opposite of the original post. Installing now, let's see how it works.
For future reference: with GraphicsEnabler=No and PCIRootUID=0, when I boot from the USB stick, I get as far as the grey screen with the apple, see the progress wheel spin for a minute or so, then my monitor goes to sleep and the system appears to hang hard.
I have a GA-H55-USB3 with i5 661, using the onboard Intel graphics card for HDMI output. BIOS version is F11 so I download Dsdt file corresponding to my BIOS version from this site and put it in /Extra.
When trying to boot into install screen, it always stops in the screen as attached. Got no good luck after using -x , GraphicsEnabler=No. Is this issue related to AppleIntelCPUPowerManagment or Bluetooth kext (I don't have Bluetooth hardware installed)
The USB install disk was created to install Mavericks on my vaio notebook and I just replace the Dsdt file for giga motherboard. Is this a possible cause to fail the installation?
The kext in /Extra/Extension of USB install disk are
I created a new install disk for installation of the desktop and use the dsdt file(F11) from this web site, still got the same problem. Then I edited the dsdt file w/ EDID info injected, but nothing changed. Do I need to buy a graphic card instead of using built-in one? Does anyone succeed in installing 10.9 w/ built-in graphic card ?
First I want to say thanks, this finally got me past my problems. Here is what I learned.
I have the Gigabyte GA-55-USB3 Rev.1 F8
BFG nVidia GTX 280
I used Unibeast to create a Yosemite boot disk WITH USB legacy support (the first time I used without and had no keyboard/mouse control at the setup screen).
Used boot switches:
-x GraphicsEnabler=Yes PCIRootUID=1
(Without the PCIRootUID=1 I would get the apple logo then it would go black and stop outputting video)
Finished install and then did the following configs in Multibeast:
UserDSDT - with my DSDT
Realtek ALC - ALC888 - Current (Rev 2 has has the 892 codec)
USB 3.0 - Universal by Zenith432
Realtek - lnx2Mac's RealtekRTL81xx v.0.0.90
TRIM Patch (if you are using an SSD)
Enable - Drivers & Bootloaders/Drivers/System/AppleRTC Patch for CMOS Reset (without this my BIOS settings kept getting reset every time I rebooted)
Under Customize > Boot Options I additionally added "GraphicsEnabler=Yes" and "PCI Root ID Fix"
