Need earlier bios version for Latitude E4310
I am trying to update the BIOS on my Latitude E4310 from version 04. The only BIOS file listed on the downloads page is version 14. But when I try to install that file, I get an error message that I must install version 07 first. How do I find earlier BIOS versions for this laptop? Obviously I want to get the BIOS to a newer version than 04.
