Another Coprocessor Driver PROBLEM (Code 28) thread  

Right click the device in device manager->Properties. Click Details tab. Select Hardware Ids in the pull down menu. Then copy/past the IDs you see into your next post

Sorry for the delay.

PCI\VEN_10DE&DEV_0AA3&SUBSYS_0AE519DA&REV_B1
PCI\VEN_10DE&DEV_0AA3&SUBSYS_0AE519DA
PCI\VEN_10DE&DEV_0AA3&CC_0B4000
PCI\VEN_10DE&DEV_0AA3&CC_0B40


Thanks for helping out !

Been hunting for the driver. In meantime, I found these instructions that worked for some people on a different thread. See if it works for you:

1. Open Device Manager
2. Right click coprocessor
3. Update Driver Software
4. Don't let Windows search the internet. Instead, have it browse the computer for driver software
5. Select the entire C:\ - or whichever drive your local disk is located on. Include subfolders in search.
6. NVIDIA nForce System Management Controller driver will be installed.

@oscer1: Great find!

If I may help further...

Hipperreal's hardware ID needs the nVidia SMU driver (footnote: after the SMU driver installs, it displays as device name "NVIDIA nForce System Management Controller" in Device Manager).

nForce install v15.56 is a collection of drivers for different devices (one of which is the SMU driver). The other driver files may not be a match for Hiperreal's h/w. So I extracted just the SMU driver from the nVidia file and put a copy to download HERE.

Hiperreal - download the SMU driver. Unzip to your Desktop. Right click on the device, select Install and then point Windows to the SMU driver folder on your Desktop to install

Hi !!

Thanks a lot to both of you !
