DIY eGPU Troubleshooting FAQ

~ deleted ~

 

Here's my problem:

I can run the eGPU setup fine and after I do PCI compaction I cannot chainload!

It says "Operating System Missing". I know this has to do with grub not loading the right partition? Problem is I don't know how to fix it.

Someone please help me out, this is getting annoying.

Hi cpkane,

Please post in DIY eGPU Experiences thread. I already responded to your post here.

 

Hello,

I have been looking around the forums for about a week now trying to solve the issue I'm having, maybe someone can give me a little insight into my error:

I am receiving the error:
"IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 0, function 1. Please contact your system vendor for technical assistance."

It does not show anything in device manager at all, I pulled that error from the event log. Although you can get it to briefly show up in Device Manager if you are watching the window while plugging in the card.

I have tried booting into eGPU setup and could not get it to detect the card there either.

My setup is the following:
-PE4H + EC2C Ver. 2
-Sapphire Radeon HD5670
-12v 6.6A DC Power adapter (800W max).

-I have an Dell Inspiron 1520 with Win 7 x64 installed.
-I'm sure I have the most recent bios, albeit it's nearly 2+ years old.
-I have 4GB of memory, I have reduced it to 2GB for troubleshooting.
-I noticed that my wifi card would be broken about 50% of the time while booting, so I removed it, still no luck.
-This machine has 3 mPCI slots underneath as well as the express slot on the side, I'm using the express slot on the side only, all others are empty.
-The bottom memory slot is now empty (the other 2GB is under the keyboard).

Any suggestions or ideas would be greatly appreciated!

Thanks.

Hi,

You should post this at eGPU Experiences thread. I already reply to your post here.

 

Hi guys,

I've been working on this problem for the past 2 days without any success and sifted as much information as I could possibly understand. It would be great if you could help pull together the info and help of sort out my setup.

Problem description

Encountered Error 12.
Attempted to use Windows 7 to reallocate but no success.
Went on to Setup x1 so that I can disable the discrete gfx and do a 32bit compaction and chainload but I am currently stuck at a GRUB error on chainloading which I have not seen anybody else describe in detail.

ie When grub attempts to chainload, it says cmain() "missing operating system".
When I attempt to manually boot Win 7 it gives me Error 13 Invalid or unsupported executable format.

I do not have any special partition format. I only have a fresh installation to 1system partition from Win 7 followed by the Setup x1 files.
Partition system is
1. System Partition 100mb
2. Windows 7 Install (128gb)
3. Data


Platform Description
1. OS - Win 7 Ultimate x64

2. System Description
Lenovo W520
Core i7 2720QM
QM67 Chipset

8GB (unknown configuration) RAM

Intel HD3000
Quadro 1000M Optimus 2GB DDR3

ExpressCard 34mm Gen2
BIOS 1.34 - Latest 21 November 2011

4. eGPU used - Gigabyte 460GTX v1.0
PSU used - Antec HCG-620 High Current Gamer 620W
Display used - 26" LCD via HDMI

I would be really grateful if anybody could help me get the setup working. I have just about everything I could possibly need but I can't seem to get it working sadly.

Any help with the GRUB error would be appreciated.

 

Hi,

Use "Chainload mbr" instead. Also set ExpressCard speed to Gen1 in Setup 1.x. You can post in http://forum.notebookreview.com/gaming-software-graphics-cards/418851-diy-egpu-experiences.html thread. You will get better attention there.

 

Is chainload mbr the default option? If yes I haven't had any luck with that.

Thanks, I'll post in the other thread as well.

27 Mar. 2012: A DSDT override extending the root bridge into 36-bit can allow ALL systems with a 64-bit CPU and chipset (anything after 2007) to be eGPU compatible when used with Windows 7 and the latest iGPU/dGPU/eGPU drivers with up to 48GB of RAM installed

drivers and installing the DIY eGPU 110b5 i get this problem: when i power on my laptop everything goes well

and it shows that the graphics card is connected however whenever i try switching it to the external display (flat

screen monitor) i get a blue screen that shows:

BCCode: 116

PC Specs: Toshiba Satellite L305, 4GB RAM, Processor Genuine Intel CPU 585 @ 2.16GHz, BIOS: InsydeH2O

I am having a problem with my egpu. It worked once perfectly and it has not again. I have the pe4l version 2.1b with a GTX 480 and a 460 watt power supply. Both of the power connectors are plugged into the card(6 pin and a 8 pin). I have a Fujitsu T900 with 8 gigs of ram an i7 dual core @3.3ghz with a 240 gig SSD. The problem I am having is the fan is spinning on the card but the card doesn't turn on. I have tested other graphics cards and they show up in my device manager. So the adapter workers and I bought a powered riser thinking that it wasn't getting enough power but it still didn't work(tested the riser with other cards and it works still). I used my volt meter to test to see if I am getting 12 volts and 3.3 volts to the card on the correct pins and I am. I also tested the card with a friends desktop computer and it works fine. I check the windows error logs and nothing pops up. I tried turning on the egpu on and plugging it in then turning the computer on but nothing and I have tried plugging it in while the computer is one and everything else. So I have tested just about everything I can and I don't know what else I can do so I am hoping that someone can shed some light one what my problem is and help me finish this thing.
