OptiPlex 760s seem to have a bug with BIOS passwords and BIOS updates when done in a certain sequence.
BIOS update fails.
BIOS update succeeds.
I've only seen this behavior with OptiPlex 760s though.
I don't know why you are only seeing that on the 760. BIOS updates are not complete until a reboot occurs so it isn't recommended to attempt BIOS modifications before that happens (like in your first scenario).
I am trying to install the BIOS update O760-A13.EXE from command line with the -NOPAUSE -NOREBOOT swtiches and it doesn't work. Can you tell me how to get this to install silently?
Correct. earlier version of the flash seemed to have worked fine. I usually run this as a command line step in an SCCM/OSD task sequence. But it fails right from the command line as well
I've tested A05 to A11, A11 to A12, and A12 to A13. All show the same behavior. This is a bug in the OptiPlex 760 BIOS. I've tested this on 740, 755,760, 960, and 990 without any issues.
During boot the error message is "Could not find the firmware image in memory". After rebooting and logging in, cctk.exe --completioncode returns 000D as the code which means "The image could not be found in memory or the header could not be located."
The above error was taken from the CCTK 1.2.1 User Guide, page 133. It is also in the CCTK 2.0 Command Line Interface Reference Guide.. <ADMIN NOTE: Broken link has been removed from this post by Dell>
By the way, the /nopause /noreboot switches work fine for me on the OptiPlex 760. Notice I used / instead of -
Create a batch file that runs O760-A13.exe /nopause /noreboot and then on the next line of script write echo %errorlevel% and when you run the script fromthe command line, see if outputs 0. After rebooting the system, run cctk.exe --completioncode to see if that is 0000.
The other weird thing is that Intel ME firmware update always seems to apply successfully since the message "ME firmware update successful" always displays during boot.
