Hi,
I have this Dell Optiplex GX1 and I have read everything online regarding the message: Alert! Cover was previously removed. I know that I have to go into Bios, but I can't. I have tried every combination possible: F1, F2, cntrl-atl-enter, and del. For some of them, if not all, I get the Keyboard key stuck failure. I have switched keyboard. Please tell me how I can get into Bios to reset the Chassis Intrusion option.

its not a lot,
