add Ventoy to boot menu

[george1421]

@youzersef OK I find a few things. I still think we can make it work.

ref: https://ipxe.org/settings
To call microsoft wds server

  set netX/next-server 192.168.1.2
  set netX/filename boot\x86\wdsnbp.com
  chain tftp://192.168.1.2/boot/x86/wdsnbp.com

translated

  set newserver:ipv4 10.xy.xy.113
  set newbootfile iventoy_loader_16000_uefi # I will explain later
  
  set net0/next-server ${newserver}
  set net0/filename ${newbootfile}
  chain tftp://${newserver}/${newbootfile}

Now to the ${newbootfile} , why did I pick that file name? From this document: https://www.iventoy.com/en/doc_ext_dhcp.html It appears that they can use dnsmasq for auto boot file identification, based on they say how external mode works. What we want is to use “ExternalNet Mode” in this case we will let iPXE decide what boot file to use. And then instruct the client to boot the proper file. So when you use the code from above, you must test with a uefi based computer. Right now I want to see if you can boot into iVentoy. We can work on the next steps after we can verity we can chain into their app.

I think its possible to use this software we just need to find the right path.

There is another ref site that I’m just logging here but I think the above is right since it from the ipxe developers directly.

@george1421 no thing changed. the PC will ask the DHCP Server 10.132.1.1 again about the the pxe.efi file.

in the boot menu entry looks like

set newserver:ipv4 10.132.7.113
set newbootfile iventoy_loader_16000_uefi
set net0/next-server ${newserver}
set net0/filename ${newbootfile}
chain tftp://${newserver}/${newbootfile}

@youzersef Understand I’m just making some guesses here because I don’t know ventoy. But if you look at the ventoy document link I provided. There is a section that talks about a drop down list on the configuration page where you need to change the dhcp server mode to ExternalNet.

The second thing is it looks like they are running a customized version of iPXE (same thing fog uses as boot loader) but its qualifying the name and it doesn’t like ipxe.efi as the file name because its not its own app. I think this is why the error is being thrown.

@george1421 i changed to ExternalNet. but nothing has been changed. I found something in the community of ventoy which could help me.

maybe you can tell me what the post means. because am not good enough in pxe.

someone posted:

I managed to chainload from my main iPXE to iVentoy, basically you need to do following things:
1. In your main iPXE boot.ipxe file, set user-class to a specific value, such as MyCustomClass
2. In your dhcp server, match this user-class and send next-server as your iVentoy IP
3. In your main iPXE boot.ipxe, run 'dhcp' command, after 'set user-class MyCustomClass' command, then 'chain tftp://${next-server}/iventoy_loader_16000'
Done

fog > ipxe menu > add option:

set net0/next-server 192.168.1.254
chain --replace --autofree ipxe.x64.snponly.efi.0

on ubuntu fog server: edit file /etc/dhcp/dhcpd.conf

class "UEFI-64-1" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00007";
    if exists user-class and option user-class = "iVentoy"{
    filename "iventoy_loader_16000_uefi";
    next-server 192.168.152.254;
} else {
    filename "ipxe.efi";
}
}

i manged to chain ventoy but the graphic is bugged

i tried on test server it is pfsense as DHCP-Server it works… Thank you.

i will try it on my main Server next week … it is windows server.

@george1421 if you want i can post the configuration that i used to configure iventoy as next server after fog server… live photos:

after i chose iVentoy…

thank you guys you made my day…

@youzersef said in add Ventoy to boot menu:

if you want i can post the configuration that i used to configure iventoy as next server after fog server

If this info would help the next guy, I would say yes. That way we can all learn from someone that has already walked the bloody path to victory. That’s what makes opensource and a community lead project work.

@youzersef
Did you got the booting ISO working normally?, seem the graphic is bugged with some modern mainboard

[youzersef]

@baovipboy156 i tested on vm and i did not get problems. I will test it on dell Laptops next week.

@youzersef
I found it, root cause: screen resolution
some monitor can’t display 1024x768…wtf, then i set it to 1280x720 it work perfectly!

[youzersef]

@george1421

do you have any idea how can i add the same rule on DHCP windows server?

class "UEFI-64-1" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00007";
    if exists user-class and option user-class = "iVentoy"{
    filename "iventoy_loader_16000_uefi";
    next-server 10.132.7.113;
} else {
    filename "ipxe.efi";
}
}

@youzersef I don’t have an immediate answer for you, but I can point you in a direction. The FOG Project has a wiki page on how to setup policies in windows dhcp server. The first section of your code is outlined in the policy. https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence

You might be able to do the user class part too, but I don’t know. Windows dhcp server policies are very similar to what you can do in linux.
