If /forceit failed, you can also try /f , or /forcetype. Let me know.
I have 2 PowerEdge R510 Servers that were previously a server from a Medical Company but have now been repurposed on my network for other functions.  Both need BIOS updates.  The problem is, they both are currently at Version 1.1.4.  When I try to run the BIOS update from within windows, It reports success and says it needs to reboot windows in order to apply the update.  After reboot, it does not update the bios and just reloads windows as normal.  I've also tried to boot from a flash drive and run the update from the executable thru DOS.  This fails reporting that the BIOS is not a DELL R510 bios and that it reports itself as " -  ".  Obviously it is an original DELL Motherboard/BIOS.  I need to perform this update because I would like to upgrade the processors to the Xeon 5650 chipset.  Any help would be greatly appreciated.  Thanks in advance!
