      @jriofrio said in Watchguard Firebox M400/M500:

      So, my only option is to flash the BIOS directly.

      Well you can still just not flash it all all. 😉 You can just install pfSense to the CF card in something else and then move it across. Or install to an SSD and put that in.

        Hey all,
        Just for a nostalgic flashback, I thought I'd pickup an M400. :)
        So I did that yesterday.
        I still have my VGA adapter, so that was an unexpected bonus.
        Not sure about all M400 units but the device I picked up, by factory default, has no Serial Console Redirect enabled at all. Tragic.
        And even with the VGA adapter in play, so far I cannot find any way to boot from USB.
        So I must digress and ponder.
        If all else fails, I will push the pfSense CE installer image to the CF, boot from CF and install pfSense to SSD from there. or, do the same but flash the BIOS first via CF boot.
        Always a plot twist I tell ya.

          @Mookatroid ..... Hello everyone, today I was able to take a look into the original CF card.
          In old DOS os I used to modify the autoexe.bat in order to boot the way I wanted.
          Does Linux has something like that in which I can make it to do something that I will be able to modify the BIOS or allows me to look into the USB sticks... Etc.
          I never tried before cause Everytime that I connected to the windows PC it wanted to format it. Yesterday I put together a PC and installed Linux mint and I was able to see the m400 CF card.
          Please let me know if there is anything that I could do here..... Good day

                @jriofrio use tab for autocomplete and ls (-la if you want 1 line for 1 item),maybe find /|grep -i afu (to find afuwhatever,that pipe before grep is on the backslash key on us keyb, -i ignore case)

                      @jriofrio i see you have no background in dos :)
                      i can clearly see afulnx_x64 (or something similar,half-hidden under message now),so use that info, tab is for when you write afu and press "tab",it will autocomplete if there are no 2 afuaa and afubb...if there are,after second tab it will list all options and you need another letter...if no autocomplete,you might have wrong path...

                              question: i did manage to run the tinym400 linux and i wasn't able to make a copy of backup.rom.
                              ONCE I FLASHed THE BIOS, i run the command to make a backup2.rom of the flash bios.

                              i shut the m400 box and took the ssd where i installed the tinym400 and connected it to mu linux PC, but i can't see the /opt/rom drive in order to get the copies of the rom backups.

                              i tried to do it through the terminal with the mkdir, mount, and all that stuff.
                              I was able to get into the ssd but still can get access to the opt/rom directory.

                              linux mint disk is of not use, i see the folders but not the opt/rom directory.
                              is there a way i can get to those files?

                                @jriofrio if it works,you dont need the bios,it is better the new one,but if you really want it,it should be in home or root(not exactly sure now with the sudo,so either /home/'username' (look at your picture,i think there was the name of user maybe),or it could be /root (if sudo works on it) ...i mean the ~ character =home
