Yes. Remove it using DiskUtility but don't create a new Partition yet.

Open Terminal and enter "sudo diskutil resizevolume /dev/disk0s2 250G" (replace 250G to and size you like) to resize your Mac OS X Partition.

Next restart with your Window 8 while pressing the Alt/Option Key and select EFI Boot.

Your Windows installation should run in fullscreen resolution (2880x1800). If its lowres something went wrong.

Hi,

I'm wondering ... how well works your internal graphic card in EFI mode without your eGPU ?

No problem at all with Nvidia GT650 m. Drivers for Intel HD 4000 are bugged.

Well you just need a Windows 8 DVD or USB stick so you can install it.

eg. I downloaded and created a DVD from within Mac OS X.

You could go to a store and grab a copy too.

It adds an USB 3.0 Port ... just like the productpage says.

Add a USB 3.0 Client Port to PCI Express-Based Systems

The USB 3380 can be used to easily add a USB 3.0 client port to any PCI Express based embedded system.

I used these instruction but had less trouble so I could skip some steps.

No Bootcamp and "# diskutil resizevolume /dev/disk0s2 250G" beeing the most important part.

If you cann't make it work I'll describe my steps.

Your tutorial explains how to create a BootCamp installation.

If you want to use "my way" you'll have to grab a copy of Windows 8 64 bit and install it without BootCamp (in EFI Mode).

If you want to use your current installation you'll have to buy eGPU Setup 1.x (take a look at the link I posted). Thats where you have to put "\config\pci.bat".

It's pretty hard to write a howto about technical stuff without using technical terms at all. Choose your method and we'll see.

You'll need eGPU Setpu 1.x and have to follow Nando's BIOS Mode Instructions to make your eGPU work.

Regarding SLI do you have one or two GTX 690 O.o

Sure. Lets start with your Windows.

Where you able to install Windows 8 in EFI Mode?

Check you Harddrive in Device Manager. If it says GPT your fine.

boony's Graphics Score is actually at the same level (GTX 670 = 23572 vs. GTX 660 TI = 24543) but the sony one has a better CPU. Does the Sony use x1.1Opt or x2?

This is mainly just hypothetical, but I was wondering if it would be possible to run an egpu off an android tablet, if you could find on with an mpcie slot?

I doubt there are gpu drivers available for Android OS. check Android-x86 - Porting Android to x86

If you want to run ab BIOS install there shouldn't be a difference in using BootCamp Assistent or not. As far as I know there are no problems at all using Win7. There still might be some drawbacks regarding USB and HDD speed but I can't comment on it right now. Maybe someone with Win7 will tell you. I'm currently running Win 8 in EFI mode (without bootcamp of course as it forces BIOS mode).

Win8 in EFI has some bugs (No internal sound and Intel HD Drivers) but I'm able to use the Intel HD with basic display drivers and shut down Nvidia GT 650m which saves alot of battery if I don't need the graphics power. Actually I'm pretty close to enabling Optimus but I'm stuck with those bugged drivers for now.

Have a look the eGPU forum for lots of information aswell.

As a sidenote: be sure to get a quadcore one if you want to run Battlefield 3

Made some tests regarding this as well. You can install the nvidia drivers by right clicking the installer -> "show package content". but they wont work anyways.

I tried some hackintosh drivers aswell without positiv results. I won't be able to have a closer look at it for now as im pretty busy. =/

Be carefull with your tests you might brick your mac os.

Hey Nando, I hate to start anything, but with that logic does that mean Apple users would only be able to get support from the official Apple website? Or any other product for that matter. I think this community as a whole is great and don't see why some are unable to receive the same amount of help.

Actually every time I have a problem that is covered by Apple I contact them directly (not their homepage) and usually have an answer within minutes, that's what I paid for. It's the same for Adobe Creative Suite, my car or what ever...

It's pretty rare that you are a paying customer, have a serious problem, professional vendors can't help but some enthusiasts on the webs can.

For sure you'll find lots of infomation regarding anything... some might actually be usefull... but most will be trash filled with smattering.

Even Open Source projects (eg Linux) are mostly supported by professionals.

Don't get me wrong communities are great especially for experimental stuff and you' probably find what you're looking for but if i have a professional at hand i'll ask him.

Installing Windows EFI mode and trying to switch graphics of my MacBook is not really intended by Apple. Thats why I'm here. Apple will just say its not supported and point at Bootcamp.

If you want to pimp your SLR AMG, Mercedes-Benz will laugh at you if you ask them for further instructions. Anyways... that's just my point of view. I don't know Villagetronic and won't comment on it.

yeah sure. my plan is to switch graphics (disabling dgpu by doing so) before booting and give it a try. we'll see what happens.

EDIT: well nothing has changed for EFI... Device manager now tells me it's not a valid driver as its unsigned which didn't happen with previous versions. If I force driver signing and boot with Intel as GPU my screen turns black after Windows spinning wheel.

i doubt i can make use of the Intel HD with BIOS. if i have some spare time i'll give it a try anyways.

The Intel HD 4000 will work on its own in EFI, just not with the eGPU also hooked up. The new intel driver seems to have fixed the need to delete the driver file to make it display something.

yeah with the whole dGPU thing you have going on in the 15", i'm not sure how it'll turn out. report back!

Really? I'm gone try those new drivers ... just saw them yesterday.

The actual graphic switching already works thanks to Linux developers but I'm stuck with those EFI driverbugs atm.

Gone do some quick tests with EFI ... BIOS will have to wait until next weekend as I'm pretty busy right now.

Intel Drivers are bugged in EFI mode. I'll probably give BIOS install a try again to see if graphics switching works for 15" models! Great news.

for my 15" model the intel hd is still shown in device manager but can't be connected to the internal while the egpu is connected.

the same happens if i try to switch graphics (650m -> intel hd) so i still believe it's intel drivers unable to handle the display.

the drivers seem to be functional in device manager and actually work offscreen.

i noticed that all 3rd party resellers removed the device aswell O.o even on ebay its gone

so yeah it's really bad news for thunderbolt eGPU's

so everyone with a functional TH05 should feel happy and shouldn't care about the recall notice.

either bootmgr.efi or bootx64.efi should work. i usually use bootx64.efi

hello. i have a 2012 13" retina MBP. win8 uefi (w/ deleted intel driver), gtx 570 via th05 (SW1=1, SW2=1-2). rEFIt. i haven't modified startup.nsh.

i'm trying to get optimus internal lcd working.

without the egpu, the internal lcd works great, but the intel hd 4000 displays to it. with the egpu plugged in at boot, after the spinner thing the DVI out on the gtx570 outputs to my external monitor, but the internal lcd goes black. i can't seem to get them both working at once, and more importantly, i'm wondering if i missed a step somewhere on how to get the egpu to render to the internal lcd. any ideas?

thank you!

as far as I know you can't enable Optimus without a functional Intel driver. As your system finds a functional eGPU it wont start the basic display drivers that currently drives your internal. My internal's black aswell.

With new Intel/Bootcamp drivers this will hopefully get fixed.

@M-Low: I started with an "old" 560 ti and made it work with the steps in my first post. After that I bought a 660 ti and received error 12 aswell. even while using the 560 ti. somehow i must have messed up my windows installation... i don't know what actually caused it. a reinstall fixed this and the problem never poped up again.

if you have your startup.nsh in place and still receive error 12 try to remove all Nvidia drivers (with some removal tool) or (if you don't mind) consider a windows reinstall.

bplus.com.tw, hwtools.net, and adapter.co.jp are still up, just updated with TH05 missing.

Nope thats not true. bplus.com.tw is down (providers default page is shown) and all international support emails are handled by this domain.

try to send an email to [email protected] or [email protected] (who's the girl writing me about the recall).

If I knew some mandarin I'd probably write the chinese support

Yeah, actually I think so too. If their site pops up again I'll ask for further infomation regarding those "issues".

Tried using that exact address, but still got stuck at the boot screen. Which string should I look for to find which device maps to what I'm looking for? I tried PCI -i -b, but don't see anything that has the string thunderbolt. There's a Seg=00, Bus=00, Dev=01, Func=01 that maps to "Bridge Device - PCI/PCI bridge, vendor 8086 Device 0155 Prog Interface 0. Is that the same as you?. I tried looking in windows device manager, but not sure which text I should be looking for either. I included an attachment

[ATTACH=CONFIG]5681[/ATTACH]

Yeah, between my post and now, I bought a mobo+CPU and the 560 TI works fine on the new rig

These are my scores booting into windows 8 EFI w/o any .nsh scripts and through the LCD display. I checked all my video settings in Nvidia control panel and also put the power settings to high performance mode, but I still get low numbers. I have 8 GB RAM, i7 2.3 Ghz. Basically the basic MBPr

Wow there seems to be something really wrong with your setup. You should receive 2000+++ Points in 3dMark 2011. I'd suggest to reinstall windows if you can.

Bus=00, Dev=01, Func=01 is correct though.

How do you "create a textfile called startup.nsh" in the root of the EFI partition I just created if I can't access it??? (It isn't mounted in OSx and I can't see it in Windows)

2. In Mac OS mount the EFI partition using terminal:

mkdir /Volumes/EFI
sudo mount t- msdos /dev/disk0s1 /Volume/EFI

You'll probably use those commands pretty often in the future I guess after the first time just press arrow up in terminal if you're lazy like me

I know it looks that way because it says "BOOTCAMP" next to the Windows partition, but I installed it using Shelltoe's instructions to the letter and, only after I installed the bootcamp drivers for keyboard, etc. (while in Windows), then did it say Bootcamp in the partition... Weird. I'm not sure if installing the drivers (Bootcamp Windows Support files) in the end made it bootcamp...

I'm in the process to reverting back to the rEFIt version you posted earlier. Hopefully we can work out this error 12 issue

You can check if you're running EFI in Device Manger. Take a look at the Volumes tab of your harddrive. It should say GUID/GPT. I actually think its EFI. For some reason my Partition is called Bootcamp aswell.

received this email, too. I just wrote them and asked for some more details as my TH05 works flawless.

Maybe not all devices are affected or it's affecting only OS X?

EDIT: email returned ... bplus.com.tw seems to be gone
