You need the drivers for the 975X chipset. Below is the link.. I have the same controller as my primary controller and these drivers work good for 32bit. I am using the 64bit now and they work also. Download the bottom driver for the Matrix controller. I would also get the inf update utility and install that. ... bmit=Go%21

i get it as an unknown device.... :shock: :roll: :roll: :roll:
can u give me the corect drivers for it? muchly apriciated

p.s. i use win server 2008 enterprise edition...

What is LPC

It is used for Windows MCE only. It can by disabled at BIOS. And named Intel® Quick Resume Technology. I don´t think that Quick Resume is supported by any other OS than Windows XP MCE Edition, Windows Vista Home Premium and Windows Vista Ultimate. Other Opreating Systems not using it. Just disable it - if you not using dualboot system.

That device that you are missing is the Infrared port.

On my lenovo X60 it is called "IBM IrDA Fast Infrared port"

I found this old windows 98 driver but it doesnt complete the install because it says "The required line was not found in the INF"

the driver is the lenovo 7xcx23ww.exe

I've been looking for the vista equivalent but have not been able to find it.

Hello everyone,

Unfortunately most of the links suggested here do not work anymore.

Anyway installing the Intel Matrix Storage drivers for Vista x64 cause the installer stop as the OS is not recognized.

I have a similar situation where ICH7 is not being fully installed: there is an Unknown Device recognized as 82801GB/GR.

Please see the attached screenshot:


According CPU-Z the mobo has an Intel i955X chipset
With Southbridge 82801GB (ICH7/R).

Any idea, please?

Note: this is for R2 but the issues should be similar.

Try to install these drivers manually via the Device Manager by unpacking the installation files with WinRAR or any other extraction tool if the automatic installation doesn't work.
