Slot Disablement
Enables or disables the available PCIe slots on your system. The slot disablement feature controls the
configuration of PCIe cards installed in the specified slot. Slots must be disabled only when the installed
peripheral card prevents booting into the operating system or causes delays in system startup. If the slot
is disabled, both the Option ROM and UEFI drivers are disabled.
Slot Bifurcation
Enables you to control the bifurcation of the specified slot. Only slots that are present in your system are
