+====== Setting Up PXE Boot with TFTP on OPNsense ======
+=== 1. Install and Enable the TFTP Service ===
+  * Go to **System > Firmware > Plugins** in OPNsense.
+  * Search for `os-tftp` and install it.
+  * Navigate to **Services > TFTP > General**, enable TFTP, and set the **server IP**.
+=== 2. Configure DHCP for PXE Boot ===
+  * Go to **Services > DHCPv4 > [LAN]**.
+  * Enable **Network Booting** and set:
+    - **Next-server IP** (the TFTP server, usually OPNsense itself).
+    - **Boot filename** (`pxelinux.0` for BIOS, `bootx64.efi` for UEFI).
+=== 3. Prepare the TFTP Server ===
+  * Upload PXE boot files to `/usr/local/tftp`.
+  * Ensure the correct bootloader (`pxelinux.0` or UEFI equivalents) is available.
+=== 4. Test the Configuration ===
+  * Boot a PXE-capable client.
+  * Verify it retrieves the bootloader from the TFTP server.
