OS X Yosemite Installer doesn't boot AMD FX CPU
2 2

Question

I have: 

1. AMD FX 8350 CPU at stock speed CPU

2. Gigabyte GA990FXA-UD3 Revision 4 motherboard with the F3i Beta UEFI/BIOS update

3. EVGA GeForce GTX 660 3Gb Graphics Card (I'm using the DVI-D Connector)

4. 1 2TB Seagate HDD and 1 160WD HDD (I want to install OS X on this one)

 

I have the OS X Yosemite Zone distro on my 8Gb flash drive.

My computer can boot to the screen where I'm asked to type in boot flags.

Since I have an AMD FX CPU, I type -amdfx -v

 

However, after pressing "return", it starts loading a BUNCH  of files, but then it restarts my computer.

I've tried -f -v, etc.. but none actually boot the system.

 

I remember, when this used to be Niresh, I installed a Niresh Distro, that mostly worked, but I don't remember which one it was.

 

Any help?

first of all, yosemite 10.10.1 doesn't have /amdfx boot option, so i suppose you are on 10.10. 

first question: did you read any installation guide?

second: did you set anything in bios?

third: did you try to boot with arguments npci=0x2000 PCIRootUID=1?

 

My specs are this:

AMDfx 8350

ASrock 990fx EXTREME 4

16GB Ram Corsair Vengeance

Zotac Nvidia GeeForce 660 ti 2GB

and lot of hd....

Currently I'm on Yosemite 10.10.1 and it works.... it was not so easy to do it, but is possible :)

any news?

 

Answer to your first question:

yes I did read a guide: http://tinyurl.com/lbenq52 which was Guide 2 of this link: http://tinyurl.com/khhal3e

I followed practically all that I could up to step 4. I do have an old iMac G4, but I wouldn't want to try to restore the .dmg file on it because it has USB 1.1 ports which are extremely slow, unless I absolutely have to.

Answer to your second question:

What I changed in the UEFI was what was mentioned in the first link I gave. The person who wrote the guide had an Intel CPU, and a Gigabyte motherboard, so some options weren't there.

Answer to your third question:

I tried the boot arguments you told me, but they didn't work either. It would load some files, and then restart. I also tried them with -amdfx -v, etc.. and it kept restarting.
