-Below is my BIOS setup, your motherboard may have a different name for the options, so you'll need to adapt it with your hardware.
+Common settings:
 
-```json
+- Enable Wake-on-LAN (WoL) and network boot
-{
+- Use UEFI mode and disable CSM (legacy) mode
-    "Devices": {
+- Disable secure boot
-        "Network Setup": {
+
-            "PXE IPv4": true,
+Boot order options (select one, each has their pros and cons):
-            "PXE IPv6": false
+
-        }
+1. Only boot from the network if no operating system found: works on most hardware but you need to manually wipe your hard drive or delete the existing boot record for the current OS
-    },
+2. Prefer booting from the network if turned on via WoL: more convenience but your BIOS must support it, and you must test it throughly to ensure you don't accidentally wipe your servers
