BIOS Setup Utilities For the IO Module entries on the NIC Configuration screen, only entries for modules which are currently installed will appear and only ports which exist on those IO Modules will appear. If an IO Module which had been installed is no longer installed when the system is booted, all NIC Configuration entries which are specific to that IO Module will be reset to their default values and hidden. If a different IO Module is installed than had been previously installed, the module-specific settings will still be returned to defaults, but not hidden. This will not necessarily affect the Option ROM settings, which depend on the aggregate capabilities of all installed Onboard and IO Module NICs. For each NIC port which is present on an Onboard NIC or IO Module other than InfiniBand controllers, there will be a port-specific PXE Boot enabling option and a MAC Address display. Onboard NICs and NIC ports also have enable/disable options. IO Modules and the ports on them cannot be disabled by BIOS. InfiniBand controllers which appear as Onboard NICs or as IO Modules have a slightly different format. They do not have enable/disable options, but they do have a choice of whether to enable loading and executing the embedded Option ROM for the controller, which will cause it to become bootable. For InfiniBand, both a GUID and a MAC Address are displayed. The GUID is used for InfiniBand Fabric operations, and the MAC Address is used when the controller is attached as an Ethernet device. For non-InfiniBand NICs, there are different OPROMs for different protocols, which are also differentiated by speed, 1 Gb or 10 Gb. For a given protocol/speed, all Ethernet controllers of the same speed use the same Option ROM.  PXE - there are two separate PXE Option ROMs, one for 1 Gb NICs and another for 10 Gb NICs. The two are independent of each other, but each must be the only Option ROM enabled in its speed class. If 1 GbE PXE is enabled, then the discs OPROM cannot be enabled. If 10 GbE PXE is enabled, then neither discs nor 10 GbE FCoE may be enabled.  discs - there is only one discs Option ROM for both 1 GbE and 10 GbE NICs. If discs is enabled, then neither PXE nor FCoE OPROMs may be enabled for the 1 GbE or 10 GbE NICs.  FCoE - there is a 10 GbE FCoE Option ROM that supports the Intel® 82599 NIC. When it is enabled, the discs OPROM and the 10 GbE PXE OPROM must be disabled Note: These Option ROMs are only in support of onboard NICs and installed IO Modules. They do not support NICs on add-in network cards, even if the NIC on an add-in card is the same type of device as an onboard NIC or IO Module controller. Only the Option ROMs for which controller capabilities are present are shown in the screen for selection. For example, if there are no 10 GbE NICs installed, then the 10 GbE OPROMs will not appear for selection. If controller capabilities are present, but all controllers with those capabilities are disabled, then the relevant OPROM options will appear, but will be disabled and grayed out and not changeable. Similarly, when the PXE OPROM of a given speed is disabled, all PXE port enable/disable options using that OPROM will be disabled and grayed out. Conversely, if all ports are disabled for PXE, the PXE OPROM will be disabled and grayed out. When a NIC Port is disabled, the PXE enable/disable option for it will be disabled and grayed out, and the MAC Address will be blank. When a NIC controller is disabled, all Ports and PXE options 104 Intel® Server System R2000IP Service Guide
