red_gOOner, The issue you are seeing is likely due to the server having been an OEM version R710. Which entails it being loaded with a custom BIOS. If the server was at the OEM 2.2.1 and then flashed back over to the standard BIOS, then it will continue to not show the BIOS information. What we will need to do is to -Flashing the system with the 3.0.0 or later OEM bios update (using /forcetype switch) this will take the system back to OEM status.   Then  -Reboot and boot to Windows, run the 6.0.7 DUP, which will then apply successfully and turn the OEM box to Dell Branded, with bios versioning information this time being intact upon reboot.  After that then you can update the BIOS back up to the latest version as you had.  Let me know how it goes.    
Hi all,  I have purchased a 2nd hand PE R710 and the system looks healthy apart from the following: I) During POST at the Blue Dell logo screen it says BIOS revision, but doesn't list a rev number ii) In the web interface for the iDrac it doesn't list the BIOS rev or model information​ I have upgraded BIOS, iDrac and Life cycle firmware to the latest revisions from the Dell website. The service tag from the chassis identifies the system on the Dell support site as a R710. The service tag is displayed on the iDrac webpage. l have tried downgrading the BIOS all the way back to 2.3.x, but this has not made a difference. I am in the process of downloading the latest Dell Server Utility to see if l have missed any firmware updates. Any suggestions? Thanks in advance
R710 BIOS rev and model information missing
