Adding Hirens 15.2 boot cd to the boot menu

[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.

: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?

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

@Wayne-Workman

nope nothing to see here

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

@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?

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

@goempie

IT WORKS

After the promt i just have to hit enter and then the hirens boots.

Thanks for the help.

I wil try to make a small guide on how to do it.

Please do! I’ll add it to the wiki after you have it made.
