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.

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 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/gami...periences.html thread. You will get better attention there.
