Brief Description

 The GUID for each board is embedded with BIOS-coding on behalf of LAN_MAC address.

This is not available to change by user unless they changed by other third-party tool.

Solution

Ensure the right MAC-address and flash with latest BIOS (or) contact FAE about to guide amd use a third party tool to fix.

 Remark

This is needed based on customer application PXE-environments, otherwise it will not impact with BIOS performance if any wrong GUID (Globally unique identifier).
