System Diagnostics

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

[Andy Abplanalp]

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…

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?

[Jarli]

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.

[Jarli]

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

[Jarli]

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";

[/CODE]

[Tom Elliott]

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

[Jarli]

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.

[Jarli]

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

[Junkhacker]

have you looked at the examples here? [url]http://www.fogproject.org/wiki/index.php/Advanced_Boot_Menu_Configuration_options[/url]

[Jarli]

We are now looking at these, thank you for the guide.
