BIOS Parameters by Server Model

Server Management BIOS Parameters for C220 and C240 Servers

Name	Description
PCIe Slot:n OptionROM	Whether PCIe expansion slot n is available to the server. This can be
	one of the following:

•Disabled—The expansion slot n is not available.

•Enabled—The expansion slot n is available.

•—The expansion slot n is available for UEFI only.

•—The expansion slot n is available for legacy only.

PCIe Mezzanine OptionROM	Whether the PCIe mezzanine slot expansion ROM is available to the
	server. This can be one of the following:
	• Disabled—The expansion slot n is not available.
	• Enabled—The expansion slot n is available.
	• —The expansion slot n is available for UEFI only.
	• —The expansion slot n is available for legacy only.
PCIe Slot:n Link Speed	This option allows you to restrict the maximum speed of an adapter
	card installed in PCIe slot n. This can be one of the following:
	• GEN1—2.5GT/s (gigatransfers per second) is the maximum speed
	allowed.
	• GEN2—5GT/s is the maximum speed allowed.
	• GEN3—8GT/s is the maximum speed allowed.
	• Disabled—The maximum speed is not restricted.
	For example, if you have a 3rd generation adapter card in PCIe slot 2
	that you want to run at a maximum of 5GT/s instead of the 8GT/s that
	card supports, set the PCIe Slot 2 Link Speed to GEN2. The system
	then ignores the card's supported maximum speed of 8GT/s and forces
	it to run at a maximum of 5 GT/s.
