BIOS.SlotDisablement.Slot7 (Read or Write)
Description
Controls the configuration of PCIe cards installed in the specified slot. Slot disablement must be used
only when the installed peripheral card is preventing booting into the operating system or causing delays
or lockups in system startup. When set to Disabled, both the Option ROM and UEFI driver are disabled,
the card is not enumerated on the PCI bus, and will not be available to the operating system. When set
to Boot Driver Disabled, the Option ROM and UEFI driver from that slot will not run during POST. As a
result, the system will not boot from the card, and its pre-boot services will not be available. However,
the card is available to the operating system. Note: This option is not available if the slot contains a Dell
PowerEdge RAID card (PERC). This option is not available if the slot contains the primary video display
adapter. Note: Some PCIe device manufacturers implement a master boot driver that can initialize and
manage all the similar devices in the system. In this case, to make sure that the Option ROM and UEFI
driver do not run, you must select Boot Driver Disabled for all the cards from the same manufacturer
(including its integrated device versions such as NDCs).
