 This guide shows you how to register a bare metal machine with Omni by PXE/iPXE booting.

 Once your machine is configured to PXE boot using your tool of choice, power the machine on.

 Navigate to the “Machines” menu in the sidebar of Omni. You should now see a machine listed.
 
 You now have a bare metal machine registered with Omni and ready to provision.
+
+## Alternative option: Use a hosting provider that supports iPXE with DHCP
+
+Some bare metal hosting providers (for example, managed dedicated server providers) already provide DHCP and an iPXE boot environment.
+
+In these cases, you don’t need to run your own PXE stack (such as Matchbox or Booter). Instead, you can chainload Talos directly from the Talos Image Factory.
+
+Use the following minimal iPXE script:
+
+```ipxe
+#!ipxe
+dhcp
+chain --replace --autofree https://pxe.factory.talos.dev/pxe/<YOUR_SCHEMATIC_ID>/<TALOS_VERSION>/metal-amd64
+```
+
+Replace:
+
+- `<YOUR_SCHEMATIC_ID>` with the schematic ID generated in Image Factory
+- `<TALOS_VERSION>` with the Talos version you want to boot (for example, {release})
+
+After the machine boots, it will register with Omni using the kernel parameters configured in Image Factory.
