My hunch is that the setting does not show up in the BIOS because you do not have an intrusion switch plugged into the MB. If you have access to the switch from the 9030 then you could plug it into the MB and the BIOS setting should show up. At that point you can disable the warning. Of course you could also secure the switch shaft in the depressed position which would accomplish the same thing but in either case you will need the intrusion switch or an intrusion switch. That switch can be found at Parts Country here and Pickclick here.
Hi, Everyone I have a dell inspiron 5348. I recently changed the motherboard. I was having a bootup problem. I changed the motherboard to "Dell Optiplex 9030 AIO All-In-One CYTN6 LGA1150 Motherboard" the problem I am having is the message I keep getting "Alert! Cover was previously removed".  the computer works fine after the motherboard replacement.  Things I have tried: Reset the motherboard ( jumper/ remove coin battery) reset the bios to default  cleared the error log in bios looked for Chassis Intrusion on the System Security screen, unable to find the option.
