      @korenchkin ...alright thanks... I was thinking perhaps this plugin will do the job of updating the Me 9.1 code but no such luck.
      I downloaded the files in your link. ... pardon my ignorance but, do i need to create a freedos boot usb flash drive and add the files to it and then boot the m400 then run the update as you stated it?
      afuefix64.efi m400-91.rom /me
      will that do it?

        Are you seeing it fail to reboot? Otherwise you don't need that.

          @stephenw10 I think was yesterday that you asked me if it reboots ok.
          so earlier today i reboot it through serial console and it hangs...
          I used to just turn it off after i did some changes. i am waiting for a sata drive to arrive so it is not online just yet. I would like to solve all the issues before goes online.
          hope the update of the Me 9.1 goes well too.

            @jriofrio this is efi shell,it just needs filesystem...it should pick up the right file...i think...for efi there is no mbr/boot sector...bios should know the name of the file to load(and be set to boot uefi,hopefully default)...i'm not certain about mbr/gpt partition table,windows uefi needs gpt,but here i probably didn't overthink it and it just booted...just try and see (and google for uefi flash boot/uefi shell,if something does not work right)

              @korenchkin .... Alright, thank you very much for the clarification, it really did help.

              I did the flashing and tested it. I restart it by the serial console and the web interface, both worked as was hoping for.
              A little reading with your comment about efi it help a lot.

              anyway, a quick question if i may. Before the flashing ME91, i was checking the bios and i saw that the image re-flash for the ME was disable, so i enable it, just in case.
              Q: should i disable it back?

              thanks one more time...

                Normally you set that and it applies to the following boot only and will automatically go back to disabled.

                Out of interest I found I didn't need to set that to update the ME. Moving the jumper was sufficient.

                  @jriofrio nice,glad it worked,for both of you i guess :)
                  I think now you know same as me,so treat your bios as yours,you have it updated,you will not update it again i guess,so maybe it will help against malware to have it disabled...

                    I should add that, as predicted, after updating the ME my i3-4160 successfully reboots. For the first time in like 7 years. Amazing! ๐Ÿ‘

                        I was not experiencing reboot issues, but my OCD kicked in so I followed the process ...
                        https://forum.netgate.com/topic/124734/watchguard-firebox-m400-m500/588
                        ... and applied the ME update via AFUDOS.EXE /ME and all went well. Maybe there are other benefits of ME 9.1.40.1000 ๐Ÿ˜
