Hey I need help to reset / clear the admin bios password on my Latitude E6220. When I booting up the dellbiosreset utility i get the message "This system is not supported by this utility (error 2)" AND "Failed to move FDD head to track 0. The FDD may not be ready for transport" I have used this tool before on E6400 with sucess. But it doesn work on E6220. Any ideas??? Thanks advice
