Sorry to be a little impolite, but you do not have a real problem. Just download the bootcamp drivers through the boot camp wizard. it won't break anything. you get a bunch of folders with all the single drivers. then you can just pick the ini file of the broadcom driver and either it works or it does not. Also it would be nice to know what kind of Windows you have installed and if it is EFI or Bios install. If you have Windows 8.1 64bit then i can tell you that i have the broadcom 6.30.223.170 driver installed. You could try the drivers from the Lenovo website then: Broadcom WIFI BCM4352 Driver for Windows 8.1 (64-bit) - ThinkCentre Systems or this link for 32 and 64 bit (not sure if its trustable) Download file broadcom_wifi_6.30.223.170_win8.rar

I will stay with Windows 8.1 Efi boot because it is fast and it works. I do not need the internal screen when at home with the egpu. just wanted to inform and maybe help others. Good News: Suddenly the brightness settings are working with the 8.1 drivers. I tried 3 different drivers ending up with https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23323 The brightness controls did not work at first. I also tried disabling the display device. then i reenabled it. And now after some reboots the controls work. When i use the function keys i do not see the white apple brightness icon. only the windows brightness control pops up in the top left. but hey, it works! PS: After some investigation: Put the macbook to standby once with the powerkey and then power it back up. then the brightness controls will work

I have refind installed. When i boot via refind and do not alter any of the settings then windows 8.1 will never recognize the eGPU. Although it is listed when i do a "pci -b". When I boot with the Mac Bootloader via pressing the alt button, then only the eGPU is recognized. I Have to admit that i cannot find anything in the refind.conf related to scanning hardware by "just removing a # from the file".

Some info on the rMBP Late 2013 13" I have installed WIndows 8.1 Efi Mode without problems. All drivers basically work. The TH05 experience is smooth But the same problem as the 15" guys with nvidia graphics. When there is another card detected the igpu disappears. Internal Screen cannot be used. Another problem are the Intel Graphics drivers from Boot Camp 5. They work, but the intel graphics menu crashes and games crash imediately. (Tested World of Tanks and Age of Empires 2 Steam Edition). There are Windows 8.1 beta drivers from intel which solve this problem but unfortunately then the screen brightness cannot be adjusted anymore. (WIth an old Macbook with Nvidia 320m i once had the luck to just set a switch in the ini file of the driver and brightness would then work on newer drivers. But i can't seem to find something like that in the inf file of the intel drivers when comparing those.)

Sorry, decided to put the info into a new thread (forum.techinferno.com/diy-e-gpu-projects/5161-rmbp-late-2013-13-info.html)

Seems like Windows is broken on the new rMBP for now: https://discussions.apple.com/thread/5475242?tstart=0 https://discussions.apple.com/thread/5474320?tstart=0 Ok, seems to be working now. Just do not use the Bootcamp-Assistant

From the side of hardware it is true. But we will also have to see, wether Windows 8 will run as good in Efi mode on the haswell mbps as it does on the macbook air 2013 (no problems with drivers for audio etc...). Then everything will be perfect

I have just received the fourth email from them. Do they stop if i just tell them i won't send it back? ^^

He needs the diagnostics file you can make in the menu of eGpu Setup while the eGpu is attatched. How he derives the pci.bat i do not know. Send him a PM maybe.

See the edited starting post for the solution thanks to nando! google

@borealiss Thanks for the link, i will try that later on. -- My next problem with egpu Setup is with the chainloader. It always goes to the eGpu Menu again and again on the usb stick. All other chainloader options in the graphical setup bring me to a grub console. What do i need to change to chainload my bootcamp partition? Thanks google

Yes I do get the Error 12.

NOTE: The US$180 BPlus TH05 (inc Thunderbolt cable) native Thunderbolt adapter used in this implementation was recalled in Jan 2013 due to (presumably) threats by Intel/Apple per TH05 recall notice. As a result refer to either of these solution that can be implemented today: http://forum.techinferno.com/diy-e-gpu-projects/4570-%5Bguide%5D-2012-13-rmbp-gtx660-sonnet-echo-express-se-%40-10gbps.html#post63754 or 2013 11" Macbook Air + Win7 + Sonnet Echo ExpressCard + PE4L + Internal LCD [uS$250].

Finally I had another problem with my chainloading. My internal harddisk was recognized as hd2 instead of hd1. So nando rewrote the grub files for me: menu.rar Now everything should be working in Windows 7 64bit Bios Mode. See the thread of kloper (http://forum.techinferno.com/diy-e-gpu-projects/2728-13-retina-mbp-win7-th05-gtx570-internal-lcd.html) for a more comprehensive description of the above adapted to a 13" Macbook Pro Retina. ------------------------------------------------------------------------------------------------------------------------- Hi,I have the setup like in the title. A iGpu HD4000 and an eGpu GTX560.I try to use the bios boot option with windows 7 as described by nando in the other thread (http://forum.techinferno.com/diy-e-gpu-projects/2367-macbook-pro-retina-15-gtx-560-ti-%40-th05-3.html#post32194).I have bought eGPU Setup 1.x and installed it on a usb stick and can boot from it.I have copied the startup.bat and pci.bat to the stick and changed the device id to the gtx 560. It is recognized.Now I have a few problems:The showstopper is, that it is telling me that my chipset cannot be recognized and tells me to run ichip after i have defined my chipset in the config file. What do I have to do to solve this.Other problems:-eGPU Setup 1.x is freezing whenever i press a button in the selection menu after the eGPU Setup start. I can only press the numbers 1-4 to select an item but any other button like F8 or up and down freezes everything.- After a random amount of time the screen goes black, i think. As far as i can tell the programm is still working because the usb sticks led still blinks when entering commands blindly. It can go black already in the blue selection screen or some time later. I happens after a random amount of time but always.Thank Yougoogle

@kloper It is working when i wait. Feeling like a fool now

Hello Macbook Air 2012 Owners: A Warning / Info about the new EFI Update. (Of course i had to try it ) TH05 Bios Mode Win 7: SW1=1 -> Internal Screen stays black. Nothing happens. TH05 Bios Mode Win 7: SW1=3 -> Windows Booting properly. eGPU not recognized at all in device manager any more. Not even with Error 12. (So, this is worse) It is working! Wait until red light goes off before selecting the OS to boot. TH05 EFI Mode Win 8: SW1=1 -> Only eGpu is working properly. iGPU (HD4000) is showing in device manager and running properly. But cannot be seen in display settings and just stays black. (No improvements on the sound situation.)(So, also no improvement here.)

Hi, just to be clear. I have a Macbook Air 2012 Win 8 EFI. With the January 2013 Intel Driver you do not have to delete the sys file to see something, but still the device cannot be started as well as the Sound device that is not working. (Bootcamp is installed.)

So, is sound also working now when the eGPU is not attatched? Thanks! google

Hey, i just wanted to throw something in about the hd4000 and sound driver issue. i read my computer hardware with sisoft sandra under efi and under bios mode. one thing that occured to me was the following difference: BIOS Mode: << SMBus (Mainboard) Deviceregister >> << Intel ICH SMBus (efa0) >> < Bus 0, Device 2C, Function 0 > 00 - 0F: 00 00 00 FC 00 6D 20 00 00 00 00 00 00 00 00 00 ..... EFI Mode: << SMBus (Mainboard) Deviceregister >> << Intel ICH SMBus (a0617000) >> Error (1200): No devices found. Does this help in any way? As wikipedia says the smbus is responsible for switching devices on/of or dimming the display. if the intel driver cant access it then we might have problems with display and sound. so somehow we have to get the Intel ICH SMBus back in place under efi!? maybe someone more tech-savvy can use this with mm command?

A gtx 680 needs around 200 watt max. i think 12V@38A is for the whole system. but you only need to power the gtx680. so what you would need is at least 12V@17A. it could also be split into two 12V@8,5A.

no, only the hd4000.

Hi, thank you for alle the information. I have two questions: Can you tell me the exact problems you run into when you try eqpu with Win 7 in EFI Mode? Theoretically i cannot see the difference to Win 8 in EFI Mode. And my second question would be: I have a Macbook Air 2012. Do you see any fundamental difference to the Macbook Pro that would interfere with an egpu on my system with windows? Thank you! google
