Unknow device R450

Hi. I am working on a PowerEdge R450 which is installed on windows server 2003.
In hardware management there is an unknown device with id device instance ACPI \ PNP90C31 / 0.
Could you help me?

Hello.

I suppose that you are referring to R410 server. Find out whether or not this device can be identified. Right click on the device and click on properties -> Details Tab and select Device Instance ID from the drop down list and post the code that you find.

RE: Unknow device R450

Why are you still using 2003??

Do you have OMSA installed? If not, then install it. It is probably the BMC/iDRAC.

thank you very much for your help.

Robert. sorry for my error. The server is PowerEdge R415. Device instance id is "ACPI \ PNP0C31 \ 0"
Theflash1932 I am using server 2003 because this server will be an engineering station of PCS7
and in this version needs 2003. I installed the OMSA but could not solve the problem yet.

RE: Unknow device R450

What drivers did you install after installing the OS?

Later install the OS without any driver I found in that situation.

ACPI \ PNP0C31


Now I found this:

Winbond Trusted Platform Module% 1.2%.

I installed the driver r167274 but it doesn´t work correctly and the device can´t start to work.
