Hmm ... interesting. 16-bit installer will only run on 32-bit OS's. Easiest thing to do then would be to boot Ubuntu and run the update from there. Or a DOS or even a WinPE disc.
 I have a Precision T7600 with a PERC H710P controller, firmware package version 21.0.2-0002, and am having battery issues -- I've seen similar problems elsewhere on this forum, but not with the same configuration.  It seems like the solution is to update the firmware, but I have been unsuccessful finding the correct firmware update for my (Windows 10) system.  Where can I find the proper update?  Thanks ahead of time.
