    Hi All,

    I’ve recently rebuilt my fog server using Ubuntu 12.04 LTS, and Fog 1.1.1 after some minor tweaks, and research I’ve got it working perfectly.

    I’ve added DBAN and NTPassReset successfully.

    Trying to add Dell Diagnostics as a additional ISO that we can use.

    It’s installed, and even starts to run, but I get

    Memdisk: loading ok
    Dell.iso: loading ok

    [B][COLOR=#ff6600]“Memdisk to large to load”[/COLOR][/B]

    [COLOR=#000000]Which is where the issue comes in. [/COLOR]

    [COLOR=#000000]Is there a limitation that restricts how large an ISO can be that Fog can load onto a local machine? [/COLOR]

    [COLOR=#000000]If so can it be raised safely without potentially crashing the system?[/COLOR]

    [COLOR=#000000]Can Grub4DOS run Dell Diagnotics successfully? If so is anyone willing to provide some insight on how to [/COLOR]

    [COLOR=#000000]1) install Grub4DOS [/COLOR]
    [COLOR=#000000]2) point Dell Diagnostics to Grub4DOS?[/COLOR]

    [COLOR=#000000]All without ruining this wonderful Fog server we have. [/COLOR]

    [COLOR=#000000]Thanks in advance. [/COLOR]

      There is no limit per say on the FOG server, however, your ram and machine specs will affect if the iso can actually be loaded and utilized.

        OK well that should be fine then.

        The system is connected to a 1G LAN connection.
        Has 4GB of RAM
        and has a i5 with 2.5 Ghz

        Any ideas on what would cause the system to load up until [B][COLOR=#ff6600]“Memdisk to large to load”. [/COLOR][/B][COLOR=#ff6600][COLOR=#000000]When I can run Memtest86+ without issue?[/COLOR][/COLOR]

          How large is the iso file you’re attempting to load?

          Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

          Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

            I may have an older Dell Diagnostics ISO but mine is only 8MB. This is what my PXE menu entry looks like:
            [CODE]:delldiag
            initrd ${boot-url}/iso/diags.iso
            chain memdisk iso raw ||
            echo failed to boot
            prompt
            goto MENU[/CODE]

            Are you using the correct memdisk parameters as above? I have also had better luck compiling my own memdisk execuatable. Here’s mine if you care to try it…

            [url=“/_imported_xf_attachments/1/1051_memdisk.zip?:”]memdisk.zip[/url]

              The iso is just over 1011MB
              It can be found here [url]http://www.dell.com/support/home/us/en/555/Drivers/DriversDetails?driverid=W0R66[/url]

                I found an older version of the ISO, which is much much much smaller at only 4MB. Will let you guys know what happens from here.

                  When I load my Dell diagnostics ISO into WinISO, it lists it as “Bootable”. When I load the ISO you referenced into WinISO, it says “Non-bootable”. Are you certain this is not one of those Dell ISOs that’s meant to run within the Windows environment?

                    It very well may be, but I’ve dropped the iso I originally found, and have a bootable version now that I am working on configuring.

                      Well with the smaller Dell Diagnostics, which is now (dell.img) i get an message which is “Bootstrap to large to load”

                      Still testing, just providing an update for anyone who may be monitoring this ticket.

                        Did you find any resolution to this problem? I’m having the “Memdisk to large to load” issue with ISOs that worked with pxe/FOG .32

                          We ended up using this ISO [url]http://downloads.dell.com/diags/DELL_32-BIT-DIAGNOSTICS_5114-2_R206154.exe[/url]
                          [LIST]
                          []With the above installer you need to run “Create a bootable image”
                          [/LIST]
                          [LIST]
                          [
                          ]This image gets saved on the fog server (at least with a stock install to) /www/fog/service/ipxe
                          [/LIST]
                          And adding this to the boot menu to BootMenu.Class.Php

                          [CODE] }
                          else if ($option == ‘fog.systest’)
                          {

                                  print ":$option\n";
                                  print "kernel memdisk iso raw\n";
                                  print "initrd diags.iso\n";
                                  print "boot || goto MENU\n";

                            It’s more preferred that you use the advanced menu option in PX E Settings because if you update the boot menu will be reset

                              We attempted to use the Advance Boot menu, but were unsuccessful.

                              Given our above example which prompted your note. Copied below.

                              [CODE]
                              }
                              else if ($option == ‘fog.systest’)
                              {

                                      print ":$option\n";
                                      print "kernel memdisk iso raw\n";
                                      print "initrd diags.iso\n";
                                      print "boot || goto MENU\n";
                              

                              [/CODE]

                              How would we add additional boot options to the advanced boot menu.

                                Sorry for coming back to this so late,

                                But how would you add a menu list outside of this using the Advanced Menu option within the PX E settings
