Description
Use this option to configure PCIe resources to
support PCIe hot-add for NVMe drives. When Normal
is selected, PCIe resources are only allocated to
devices installed at boot time, and PCIe hot-add is
not supported. When Medium is selected, additional
PCIe resources are allocated for each PCIe Root
Port, which might enable a PCIe hot-add event to
work without requiring a system reboot to enumerate
the device. When High is selected, a maximum
amount of PCIe resources are set aside to allow for
the best chance of supporting a PCIe hot-add event.
You can only configure this option if the Workload
Profile is set to Custom. If a PCIe device does not run
properly at its optimal speed, lowering the speed at
which the device is running can address this issue.
This option enables you to lower the maximum PCIe
speed at which the server allows PCIe devices to
operate. You can also use it to address issues with
problematic PCIe devices. Setting this value to
Maximum Supported configures the platform to run at
the maximum speed supported by the platform or the
PCIe device, whichever is lower.

Description
Select this option to enable or disable PCI devices.
Use this option to configure the PCIe Link Speed for
the selected device. When configured for Auto, the
selected device trains at the maximum supported
speed of the PCIe link. When configured for PCIe
Generation, the selected device trains at a maximum
of PCIe Generation 1 linkspeed.
Use this option to configure the PCIe Link Power
Management (ASPM) support for the selected
device.
Use this option to enable or disable Device Option
ROM.
