Adding Hirens 15.2 boot cd to the boot menu

[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!

@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.

@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

@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

[goempie]

@Wayne-Workman
I moved the hbcd.iso to the directory /var/www/fog/iso/hbcd.iso
Then i changed the menu entry, but no party

:hbcd
#open iso with iso editor and remove pmagic to make it ligther
set path /fog/iso
set nfs_path /var/www/fog/iso/15.04_64
initrd ${fog-ip}${path}/fog/iso/hbcd.iso
kernel ${fog-ip}$ kernel memdisk iso raw || goto failed
boot || goto failed
goto start

[Wayne Workman]

@goempie the pathing is wrong. you already have /fog/iso in your path variable, don’t need to do it again.

also I don’t think you have to specify an IP for the memdisk kernel.

[goempie]

@Wayne-Workman

Yes i saw it after i posted it.
This is what i have now
But still no champagne
:hbcd
#open iso with iso editor and remove pmagic to make it ligther
initrd ${fog-ip}/fog/iso/hbcd.iso
kernel memdisk iso raw || goto failed
boot || goto failed
goto start

[Wayne Workman]

@goempie

try

:hbcd
#open iso with iso editor and remove pmagic to make it ligther
initrd ${fog-ip}/fog/iso/hbcd.iso
kernel memdisk iso raw
boot || goto failed
goto start

also - make sure the permissions on the iso are good, can you see it in a web browser?

#open iso with iso editor and remove pmagic to make it ligther
initrd ${fog-ip}/fog/iso/hbcd.iso

Yep i can see the iso in the browser and can download it.

[goempie]

This is what i see when i go to /fog/service/ipxe/boot.php

So i don’t think tha the :hbcd in the begining is necessary.
But i deleted it and stil it doesn’t work.

@goempie
I did a little digging - this thread looks very promising:

https://forums.fogproject.org/topic/3229/ipxe-iso-boot-problems

Specifically this post:

@csurepair said in IPXE ISO boot problems:

Wahoo!!

Shes up and running! Thank you both for the feedback, you guys deserve a beer! If your ever in Fort Collins, Colorado PM me haha.

So for everyone else my problem was totally due to syntax and directory location,

By changing CODE initrd ${fog-ip}/fog/iso/Hirens152.iso[/CODE] to CODE initrd http://${fog-ip}/fog/service/ipxe/iso/Hirens152.iso[/CODE] iPXE was able to fully resolve the path. This was only accomplished by making iPXE produce some sort of feedback via the below code(most graciously posted by Junkhacker),

menu
item --gap – ---------------- iPXE boot menu ----------------
item BOOTCD Hirens BOOTCD
item shell ipxe shell
choose target && goto ${target}

:BOOTCD
initrd 192.168.1.130/fog/iso/Hirens152.iso ||
echo failed to load iso if it stops here
prompt
chain memdisk iso raw ||
echo failed to chain memdisk if it stops here
prompt
boot ||
echo failed to boot here if it stops here
prompt
goto MENU

:shell
shell ||
goto MENU

autoboot[/CODE]

Thanks again guys!!

@Wayne-Workman

Ok getting there.

initrd http://${fog-ip}/fog/service/ipxe/iso/hbcd.iso ||
echo failed to load iso if it stops here
prompt
chain memdisk iso raw ||
echo failed to chain memdisk if it stops here
prompt
boot ||
echo failed to boot here if it stops here
prompt
goto MENU

When i boot i see that it downloads the iso then it comes to 100% and then i get the message

failed to load iso if it stops here
