Event ID 1004 — IPMI Driver Functionality

Applies To: Windows Server 2008

The IPMI driver supplies the IPMI WMI provider with data from the Baseboard Management Controller (BMC).

The IPMI driver is a Windows Driver Model (WDM) kernel mode driver that communicates with the BMC by using Keyboard Controller Style (KCS). For more information about driver installation, see Installation and Configuration for Windows Remote Management. The IPMI driver appears in the Device Manager as Microsoft SMBIOS Generic IPMI Compliant Device.
