When switching a latitude 3340 to UEFI boot mode, it no longer puts astricks (*) next to USB and PXE boot devices in the F12 menu.
I have been able to prevent a security concern by turning off UEFI network stack and USB boot support.
I always liked the way Dell BIOS's had a method of leaving boot options available in the boot menu but prompting for admin passwords. It saves a couple reboots when we have to image computers. Does anyone have a method of restoring this functionality?
