There are a lot of issues with version numbers when it comes to firmware and drivers. I would like to hope that some sort of consistency or collaboration between those who type the documentation and those who type the web text could somehow get together and come to an agreement as to what the REAL version number is.
A bios firmware version listed as 2.4.3 is not the same as the documentation and file name version of 02.04.03
Zeros are important. use them where when and if they are needed. but Don't remove them in the titles IF they are really part of the actual version.
