Need some help to get booted onto installion (AMD)
2 2

Question

Hi, I am having some trouble getting my computer to load up Niresh 10.8.5 and thought I would ask for some help here instead of giving up like I have with previous versions

 

My system is:

 

Motherboard: Gigabyte GA-78LMT-USB3

CPU: AMD FX 4130 3.8GHz Quad Core

Memory: DDR3 8GB

Graphics: ATI 3000 (Built into motherboard)

 

I have booted up and entered the flags: amdfx USBBusFix=Yes -v

 

this is how far it gets to

Thanks for any help in advance

For me the following works perfectly. Burn ISO on DVD, also burn the same ISO on a USB stick.

In your bios put DVD drive first and your HD second (AHCI)

Boot from DVD and wait for the menu. When you see the menu take the USBstick en put it in your PC.

Now refresh the menu by pressing F5. Your USBstick will be visible. Navigate to your USBstick and hit enter.

(don't forget your boot flag depend on the type PC your using).

 

This method resolved my "waiting for root device"

 

My combo is a 2,9 Ghz AMD Athlon 64x2 Dual core 5600+ x 2

Graphics GTX 260 Black edition

Motherboard ECS GF8100VM-M3 (MCP78M-M3 V:1.0)

I used only the flag "amd64"

 

Everything works right out of the box.

 

Hopefully this works for you and others ;)

Yes I switched to achi and yes I think it's the clover bootloader if that's what starts up with the disc

I've unplugged other devices, even swapped cd drive and hard drive but still getting the same message. Just going to keep reading through topics and trying anything that looks like it could work.

Decided to give up trying this now. Tried a lot of boot flags, different graphics card and everything recommended in here so I'm guessing my CPU isn't supported so I'll have to wait till I upgrade my computer sometime in the future

Use these flags, They could help you. I think that "npci=0x2000" or "npci=0x3000" will help you. Just try and post your results.

amdfx npci=0x2000 -v PCIRootUID=1
amdfx npci=0x3000 -v PCIRootUID=1

Massive thanks to you for this. I have finally got it to boot :) All I need to sort now is to get the keyboard and mouse to work when it comes up but I'm guessing that should already be on here somewhere how to solve that. If I get stuck again I will ask for help

 

For me the following works perfectly. Burn ISO on DVD, also burn the same ISO on a USB stick.

In your bios put DVD drive first and your HD second (AHCI)

Boot from DVD and wait for the menu. When you see the menu take the USBstick en put it in your PC.

Hi

 

I'm having a bit of trouble with getting past the Clover screen when trying to get to the Mac OS installation screen. 

 

I've changed my BIOS from IDE to AHCI with both USB's plugged in but I'm getting this screen, but not the 10.5 installation image

When I try and press boot external I just get a blank screen with a flashing cursor & I've added the -v within the options

 

System: 

Phenon X6 II X6 1090T

Chipset shows as Northbridge

Mobo: Asus Crosshair Formula IV

Graphics: ATI RadeonHD 5850 

 

Any suggestions would be helpful 

 

Cheers!
