drivers are disabled. Only slots that are present on the system will be available
for control. When this option is set to boot driver disabled, both the Option
ROM and UEFI driver from the slot will not run during POST. 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.
