FWIW, I updated my XPS 8930 to BIOS 1.1.24 and it seemed to go faster than I expected/remembered. And yes, it's annoying when those same BIOS settings revert to their defaults instead of staying the way the user sets them.
I installed BIOS 1.1.24 for my 8930 this morning.  As usual, using the USB stick worked with no problems.  Took about 5 minutes from start to completed and back at normal start screen.  The Dell support site says it is a security related update.
