    Bios update on DC53427HYE fails


      I'm trying to update my DC53427HYE to BIOS version 49 via the F7 procedure. The updater recognizes my USB drive and the RK0049.bio file on that drive but after confirmation the system immediately reboots instead of starting the update. After the reboot the BIOS Event Log shows the message "Flash Update Failed (21)". Does anyone know the meaning of this error 21?
