2. Windows7
3. Yosemite

BIOS:

• Default HP BIOS settings
  
• HT disabled
  
• All Cores Enabled
• Firewire IEEE1394 disabled
• SATA RAID+AHCI

I used for installation:

• Unibeast 5.1.0
• USB: add in in folder "\Extra\Extension\" this files:

1. AppleACPIPlatform.kext
2. AppleAHCIPort.kext
3. FakeSMC.kext
4. IOAHCIFamily.kext
5. IOPCIFamily.kext
6. LegacyAppleAHCIPort.kext

- boot verbose with command: -v -f kext-dev-mode=1 npci=0x2000


Installation:

1. Only once with this command I see my hard disk, otherwise I see only the USB pendirve.
2. I was able to format the partition Yosemite mode Mac OS journaled.
3. Ok, installation ends at 100%.

Post-Installation Using MultiBeast

1. Restart from Yosemite partition, loads and the icon "ban" on a gray background.

What can I do?

Your best bet would be to conduct a Google search. The main issues will be with respect to the motherboard-- and I don't think you're going to find a lot of people here with one of these systems.

Good luck!
