CauseCause
You are attempting to boot to an option that does not have a UEFI Option ROM driver.
ActionAction
1. Verify that your option card has a UEFI option driver (Option ROM) that supports either x64 or EFI Byte Code for boot
functionality.
NOTE:NOTE:
UEFI drivers do not display messages on the System Utilities screen or provide function key prompts.
If you replace the motherboard, UEFI variables are lost.
You must configure PXE servers with a boot image. For x64 EFI machines, you must also configure the DHCP
server to support x64 EFI DHCP boot requests. For more information, see the UEFI Information Library:
