Never tried myself, but other posts here have instructed people who have updated processors and had trouble to put old CPU back in, update bios and then put new processor back in.
Those instructions tell me that it probably won't work. without a CPU. You can always try, it would be a go/no go attempt.
Search this site for new cpu wont boot.
