@koenr said in Dell Latitude 3500:

class “LATITIDE-3340” {
match if substring(option vendor-class-identifier, 0, 32) = “PXEClient:Arch:00007:UNDI:003016”;
filename “realtek.efi”;
}

This will cause other systems to fail. There is nothing unique about “PXEClient:Arch:00007:UNDI:003016” multiple hardware will match.

Also order that the item appears in the list is important. The first match wins rule. For Dells the UUID field of the ethernet header should be unique within a model. If you use wireshark you can pick up the uuid of the pxe booting computer in dhcp option 97. You can tell if you have the right value because the first 4 characters spell DELL in reverse in ascii.

The other option if you only have a few of these devices is to use mac address matching to target specific computers with specific boot loaders.
