Gigabyte GA-X58A-UD3R rev.2 - Chimera won't start from USBStick

Gigabyte GA-X58A-UD3R rev.2 - Chimera won't start from USBStick (solved)

Hi there,

I tried two different USB Sticks, different USB Ports, but still after choosing "USB-HDD" Chimera doesn't start, it goes just to the spinning "/" and stops after 2-3secs, no further information on screen.

The USB Stick was builded on a 10.9.4 MacBookPro (english as main language) with Unibeast 3.0.1 like described here: http://www.tonymacx86.com/374-unibeast-install-os-x-mavericks-any-supported-intel-based-pc.html

The Machine has following stuff inside:

i7-920
6x1GB 1066 RAM
Sapphire Radeon 6850 with 2GB VRAM
Samsung 830 SSD (with Win7)
Sata-HD which should get Mavericks

The Bios on the Gigabyte GA-X58A-UD3R was changed from optimal settings to:

HDD Smart Capability = [Enabled]
SATA RAID/AHCI Mode = [ACHI]
Onboard SATA/IDE Device = [ACHI]
USB Keyboard Function = [Enabled]
USB Mouse Function = [Enabled]
HPET Mode = [64-bit Mode]

I made different tries with Sata3 and Firewire disabled and some other changes in the BIOS like CPU EIST and CPU Thermal Monitor deactivated, same stop at "/".

I had the Mainboard changed from a Dell Studio XPS 435MT, which had a stable OSX 10.7.2 via Unibeast etc. for the last years with the same Graphics, RAM and HDs.

Is there anything else I should check, change or do different?

Thanks in advance!

Choose HDD, then select the USB from the HDD list.

...thanks, that's something I haven't tried yet. but, no change, the "/" spins 1-2x and then freezes.

I should mention that the Gigabyte runs on Bios FH.

At the moment I have all Advanced CPU Core features enabled, like advised here: http://lnx2mac.blogspot.de/2010/07/optimal-bios-configuration.html
.... is anything there that should better be disabled?

I give it some more tries with different Monitor-Cables now, as this was in earlier osx86 times a boot-problem from time to time.

btw: is it possible to burn a unibeast-prepared usb-stick on a dvd and boot from that?

Which USB port is the UniBeast connected?

I find the ones next to the RJ45 network connector work best.

Ok, after a quick try with Clover ... which also didn't boot, I tried some hardware changes and disconnected the internal SSD (was on SataII) and this caused the Chimera Problem.

Now the Unibeast-prepared Stick was booting into Chimera, but it didn't went through to the installer. I guess the problem with this is the Radeon 6850, but I'm gonna sort that out...

I did remove the AMD6000 Kext from the Unibeast Stick ... like discussed here in the 2nd answer:
http://www.tonymacx86.com/mountain-...-ati-5770-batmobile-mountain-lion-10-8-a.html

Booted with "GraphicsEnabler=No -v".

At the moment it stucks after 'bluetooth'-something. Tonite I have more time and give it some more tries....

Last weekend I gave it a try from the scratch and after formatting the SSD everything worked pretty smoothly. The bluetooth error didn't appear again after I put a cheap BT4.0 USB Stick in the machine.

Now everything works pretty fine.

I got Win7 on the first partition of the guid-formatted SSD (installed also first) and then OSX 10.9.4 with Chimera. Some things didn't work out of the box, but Multibeast activated this stuff.

I used the DSDT from this link http://www.tobiasfeigl.de/2013/07/2...-ud3r-rev-2-1-for-os-x-tested-10-7-10-8-10-9/
and did it with Mavericks like jeremyndt in this post: http://www.tonymacx86.com/mountain-...-ati-5770-batmobile-mountain-lion-10-8-a.html
Even Radeon 6850 didn't make any trouble. First OSX boot after install was done with these flags "-v -x GraphicsEnabler=No". Only thing I added here in Multibeast was the 10.9.4 TRIM fix for Non-Apple SSDS.

Multibooting to 10.9 or Win7 is absolutely perfect and both systems run perfectly for me. Only wake from sleep doesn't work properly in 10.9 and BT4.0 can not put off , but I can live with that.

The Chimera bootproblem came probably from the earlier SSD format on the old dell-machine ... it was done in an external USB on the old Dell machine and after a clean format it worked, just in case someone has a similar problem with Chimera booting.
