What can result from a computer losing power during a BIOS upgrade if the computer does not have
a FailSafe Boot Block?

A.
The computer reverts to the earlier version of BIOS because HP BIOS updates are fully redundant
and include built-in backup and restore in case of power loss during upgrade.

B.
The update fails, but HP BIOS updates can always be re-run to return the computer to a working
state even if power is lost during a BIOS update.

C.
The system ROM can become corrupt causing the system board to fail requiring replacement of
the system board.

D.
The system memory can become corrupt requiring replacement of the memory.
