Within the past year, Dell has slightly changed how they give version numbers to BIOS updates for newer models.  For example, before this change BIOS version 1.1.9 gets replaced with 1.2.0.  But after the change, instead 1.1.9 gets replaced with 1.1.10.  Or, 1.9.1 gets replaced with 1.10.1.  There is a problem with this change. When organizations use SCCM OSD imaging to update the BIOS, they often will WMI query the version number of the BIOS to see if it needs to be updated with the one on the server.  However, it thinks that version 1.1.9 is higher than 1.1.10, because in reality 1.1.9 is a larger number, so it thinks the BIOS doesn't need to be updated but in reality it does.  Please go back to the older BIOS numbering system
