Solved? AMD Gigabyte f2a88x-d3h board: not booting from Yosemite partition

[HangDog1]

Hi all

I am a new boy on the block, hope you can help me.

 

After some too-ing and fro-ing, got USB installer and finally installed Yosemite 10.10.5 on partition on SSD drive.

Now booting from the OS X partition, there is a scroll of characters on the screen then a  get a flash of black screen then stays on a blank dark grey screen. I have tried the usual boot flags but to no avail.

 

Thanks in advance

 

 

MY HARDWARE:

 

CPU:           AMD Athlon X4 860K Quad Core Processor .

 

Motherboard:   GIGABYTE F2A88XM-D3H

 

Chipset:       AMD A88X (Bolton-D4)

 

Memory:        8GB    2 x 4096 MB PC12800 DDR3 Kingston SDRAM 

 

Graphics:      GIGABYTE Radeon R9 270

               

SSD Hard drive Drive:       KINGSTON  120 GB, Serial ATA .

Hard Drive:                        WDC  500GB, Serial ATA 6Gb/s @ 6Gb/s

Hard Drive:                        Hitachi 250GB, Serial ATA 3Gb/s

Blu ray Drive:                     LG BD-RE  writer

 

Sound:         AMD Hudson-2/3/4 - High Definition Audio Controller

Sound:         ATI/AMD Verde/Heathrow/Chelsea - High Definition Audio Controller

Thinking of replacing above with SoundBlaster Z-series board.

 

Network:       RealTek Semiconductor RTL8168/8111 PCI-E Gigabit Ethernet NIC

 

OS already installed: Windows 7 Professional (x64) 

 

 

Used the following: 

 

Apple OS:          Yosemite 10.10.5 

 

Bootloader:        Chameleon-2.3svn-r2716  with Chameleon wizard and Kext wizard.

 

AMD kernel:        10.10.5_SSEPlus_V3

 

MBR patch    Yosemite MBR Patch 10.10 (14A389)

 

NullCPUPowermanagement.

 

Eventually solved by copying the kernel from the installer usb to the Systems/Library/kernels on the Yosemite partition on the SSD.  

Booths to Yosemite screen, but not full screen, no sound.  Trying to sort out with DSDT/ SSDTs.
