What is the MEBx BIOS hotkey combination on a Dell Optiplex 7040? The option is enabled in bios but when I try the standard combination ctrl+p it doesnt work.
I have tried on different machines.
Skylake systems which have previously gone through set up and configuration using MEBx will not revert by selecting full un-provision in BIOS settings.
Older system versions of OptiPlex systems which used Legacy settings could undergo a reset by selection of settings in BIOS under the MEBx interface.
Skylake systems are unable to use BIOS options to reset the system settings in case of lock out. In order to restore MEBx to default settings (See Figure 1.), a CMOS reset using the RTCRST jumper pins on the motherboard must be completed.

MEBx Password Reset is completed using the Real Time Clock Reset (RTCRST) Jumper pins on the motherboard to Clear Previous Configurations
