Unknown Device for Intel D975XBX Mobo

Aspro · Post by **Aspro** » Mon Jun 05, 2006 11:38 pm

I've just booted up the first new system I've built using Windows XP Pro SP2 on an Intel D975XBX mobo Revision 303 and I note that I have an 'Unknown device' listed under 'Other Devices' in 'Device Manager'. Looking at the properties for this device the 'General' tab details 'Location' as "on Intel 82801GH (ICH7DH) LPC Interface" while the' Details' tab lists 'Device Instance Id' as "ACPI\AWY00001\4&3036D68D&0".

Can anyone shed any light on the "Unknown Device" from the information above?[/b]

I've run the Intel Express Installer Driver CD after installing XP (as recommended by Intel). The only drivers that haven't been installed that were on the CD are "Silicon Image" and "Intel(R) Matrix Storage Technology" and my understanding is that both of these drivers relate to RAID. One of the drivers that were successfully installed was for the Chipset.

I've now applied all the latest XP updates however the "Unknown Device" still remains a mystery.

It would seem to be associated with the "LPC Interface", whatever that is (I think LPC stands for "Low Pin Count").

Just to complete this post I have found out from Intel Support that the missing driver is the "Intel Quick Resume Technology Driver" used in digital entertainment systems and requires the Windows XP Media Center Edition OS amongst other requirements.

As the Intel D975XBX mobo supports Intel's Viiv technology the default BIOS settings had this device enabled. On disabling this setting in the Power Menu of the BIOS all my problems disappeared.

Thank you everyone for all your help.

I have a NF4 board and I also have an "unknown device". I have onboard audio and LAN disabled. I installed the nForce4 board drivers and it hasn't gone away. I just ignore it as I can't get rid of it.
