Adding Hirens 15.2 boot cd to the boot menu

[goempie]

In the wiki there is a guide to add hirens boot cd to the boot menu.
link text
I have followed the wiki but the wiki is a bit old and it’s a little different with the new fog.

When I add the following in the parameters then fog stops working.

:MENU
menu
item --gap – ---------------- iPXE boot menu ----------------
item ubuntu15.04_64 Boot Ubuntu 15.04
item return return to previous menu
:ubuntu15.04_64
set path /fog/iso/15.04_64
set nfs_path /var/www/fog/ISO/15.04_64
kernel http://${fog-ip}${path}/casper/vmlinuz.efi || read void
initrd http://${fog-ip}${path}/casper/initrd.lz || read void
imgargs vmlinuz.efi root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:${nfs_path} ip=dhcp splash quiet – || read void
boot || read void
goto start

I have tried leaving some parts out like this:

:ubuntu15.04_64
set path /fog/iso/15.04_64
set nfs_path /var/www/fog/ISO/15.04_64
kernel http://${fog-ip}${path}/casper/vmlinuz.efi || read void
initrd http://${fog-ip}${path}/casper/initrd.lz || read void
imgargs vmlinuz.efi root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:${nfs_path} ip=dhcp splash quiet – || read void
boot

Then fog keeps working but the hirens won’t boot.

Also the wiki say’s hirens 15.04 but the newest versions of hirens i can find is 15.2.
Anyone have an idea how we can do it in the new fog?

Thanks

I dont’ know what you’re doing.

From what I can tell, there is no function called “start”.

There’s no function called “return”

My guess, you need:

:MENU
menu
item --gap – ---------------- iPXE boot menu ----------------
item ubuntu15.04_64 Boot Ubuntu 15.04
item return return to previous menu
:ubuntu15.04_64
set path /fog/iso/15.04_64
set nfs_path /var/www/fog/iso/15.04_64
kernel http://${fog-ip}${path}/casper/vmlinuz.efi || read void
initrd http://${fog-ip}${path}/casper/initrd.lz || read void
imgargs vmlinuz.efi root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:${nfs_path} ip=dhcp splash quiet – || read void
boot || goto MENU
:return
params
param mac0 ${net0/mac}
param arch ${arch}
isset ${net1/mac} && param mac1 ${net1/mac} || goto bootme
isset ${net2/mac} && param mac2 ${net2/mac} || goto bootme

Of course we would need to see exactly what your system is showing via the browser.

Ok, I guess we better test and then update the wiki on this stuff: https://wiki.fogproject.org/wiki/index.php/Include_any_ISO_in_the_FOG_Bootmenu#Hirens_15.04

When I add the above in my menu then i get this

@Tom-Elliott
I’m following the wiki, otherwise I have no idea what i’m doing

[Wayne Workman]

@goempie So, let’s look at where you are?

You got to the boot menu, and the FOG background image is displayed. So at this point, you’ve successfully gotten a boot ROM via TFTP, it loaded correctly, and now that ROM is following specific instructions for the Hirens boot entry.

“File not found” seems pretty obvious, right? Some way or another the files the boot menu item is requesting are simply not available. This could be that… permissions are not set right, or the files simply are not there (in the wrong directory or typo in path or filenames. Linux is CASE SENSITIVE).

Look over your boot menu entry again, and look over where your files are on the fog server again. Make sure everything is jiving. Check permissions on those files as well.

Are you using NFS mounting at all for this? Yes you are, I just looked at what Tom posted. Did you export the /var/www/fog/iso/15.04_64 directory via NFS? If not, it wouldn’t exist I guess!

[goempie]

@Wayne-Workman
yes i’m using nfs mounting, i extracted the iso to the directory as it say’s in the wiki.

I just don’t get where this is pointing to:

kernel http://${fog-ip}${path}/casper/vmlinuz.efi || read void <---- there is nog casper/vmlinuz.efi in the iso that i extracted?
initrd http://${fog-ip}${path}/casper/initrd.lz || read void

[goempie]

@Wayne-Workman
This is the file structure of the hirens boot cd.
And I can reach it through a browser.

[Wayne Workman]

kernel http://${fog-ip}${path}/casper/vmlinuz.efi || read void <---- there is nog casper/vmlinuz.efi in the iso that i extracted?
initrd http://${fog-ip}${path}/casper/initrd.lz || read void

These two things are your kernel and your init.

so fog-ip is auto-filled in with your FOG IP. The path is set in the boot entry, it’s this line:
set path /fog/iso/15.04_64

So your path would be /fog/iso/15.04_64

Put that all together and you have a web URL:

x.x.x.x/fog/iso/15.04_64/casper/vmlinuz.efi

Where x.x.x.x is your fog server IP, of course.

What the iPXE boot script is trying to do is load the kernel and init via HTTP, through a web request basically.

So… it may be that the mounted directory cannot be read by Apache due to permissions or placement, or it could be that the files listed there just aren’t where they should be.

Either way, you need to sort that out, or figure out how to do it via NFS fully. In the wiki link below, you’ll find an example in the “Parted Magic - Older” area. Not sure if a Linux kernel will work with Hirens though! Probably not!

[Wayne Workman]

@goempie the “boot” folder in that picture you posted looks promising… look around in there… Maybe you’ll find the files you need to point to…

[goempie]

@Wayne-Workman

The whole directory /casper/… just isn’t there, and its not explained in the wiki how they get there.
It just say’s extract the hirens boot cd to the directory /fog/iso/15.04_64

I’m not shure to wich file i should point in the hirens iso to make it boot.

[goempie]

@Wayne-Workman
There’s only one file in there

[Wayne Workman]

@goempie I did a little looking, the below thread over at ipxe.org may be of interest to you:

http://forum.ipxe.org/showthread.php?tid=7052

There’s an example in there that someone claimed works. It might need adjusted though as those posts are from 2013.

If you get it working, please do list your steps.

[goempie]

@Wayne-Workman
:hbcd
#open iso with iso editor and remove pmagic to make it ligther
initrd ${boot-url}/images/hbcd152.iso
kernel ${boot-url}/memdisk iso raw || goto failed
boot || goto failed
goto start

In the above example they are pointing to the *.iso file itself.
So this means that they don’t mount the iso on the fog server?

[Wayne Workman]

@goempie Looks that way, yes. And looks like they are using the standard Memdisk kernel too.

[Wayne Workman]

@goempie But I don’t think that fog has a boot-url iPXE variable. You may need to piece that together with the fog-ip variable and set a path like in the other examples.

[goempie]

@Wayne-Workman what is the path to the memdisk kernel?

[Wayne Workman]

@goempie said in Adding Hirens 15.2 boot cd to the boot menu:

at is the path to the memdisk kernel?

Look at the boot menu entry for memdisk… You should be able to see it through the web interface.

[goempie]

@Wayne-Workman

nope nothing to see here

[Wayne Workman]

@goempie
I pulled this from the boot.php output when I gave it a registered MAC as a parameter.
http://x.x.x.x/fog/service/ipxe/boot.php?mac0=00:1e:37:54:9b:70

kernel memdisk iso raw
initrd memtest.bin
boot || goto MENU
