Keeponsmilin,  What you will need to try is to flash the BIOS to current. You can't just jump to the latest update, as that can cause issues. Go to the BIOS section on this link and then gradually update to the current revision.  ftp://ftp.dell.com/Pages/Drivers/poweredge-t710-all.html#BIOS You will see folders to the right, hover over it and it should show what link address is for each. The folder you click on for the updates is the one that will resemble T710-######C.exe, thats the non packaged version. Download those for each and you can boot to this 32bit diagnostic - ftp://ftp.dell.com/FOLDER00268256M/6/Diagnostics_Application_P10CJ_WN32_5154A0_5154.1.EXE then exit from the menu to the command prompt. From there run the .exe file to update.  That diagnostic download needs to be run from a windows system to create the bootable media. Let me know how it goes.
Just received T710 system board as replacement for old one (old had bent pins on 2nd CPU socket from factory discovered when uncovered). Need to add 2nd CPU Replacement board booted OK initially but had 2.1 version bios. Needed to upgrade to latest 6.4. Did Windows upgrade, was notified upgrade was successful, but system will not boot because of corrupted bios. Can this be salvaged (can idrac fix it) or does the board go back? Thanks
