Dell EMC OpenManage Server Administrator

Slot Bifurcation

Auto Discovery Bifurcation Settings

Allows BIOS to dynamically scan for PCIe devices rather than relying on the system slot definitions. The platform default setting will follow the system slot definition when configuring the PCIe slot. This feature will analyze the installed PCIe cards and determine the correct configuration for each slot. This may include bifurcation of the slot for multiple devices. Manual control allows the user to override the bifurcation settings

NOTE: Improper configuration of the PCIe slots can prevent the system from functioning properly.

Disables (default) or enables the TPM PPI Bypass Provision.
