 **BIOS Setup:**
-It is recommended to use the coreboot+UEFI BIOS, as such there is no configuration needed. Whether you use a serial or video console, it just works.
+It is recommended to use the coreboot+UEFI BIOS, whether you use a serial or video console.
+On startup (quickly) press the ''<DEL>'' key to enter the BIOS Setup.
 !!Tip ->!! When using macOS via the console USB cable, to enter ''DEL'' use ''Fn'' + ''delete''

+Go to the "Power Management Options".  Make the following change...
+{{:userdoc:protectli_vp2430-bios-power.jpg?nolink|BIOS Power}}
+Go to the "Change Boot Order".  Make your SATA/NVMe drive the first choice.
+{{:userdoc:protectli_vp2430-bios-boot-order.jpg?nolink|BIOS Boot Order}}
+!!Tip ->!! Sometimes the "Change Boot Order" does not work as expected, alternatively remove "Network Boot and Utilities" as a boot option, leaving only your SATA/NVMe drive as a boot choice.
+\\
+**Disable CPU C-states:** (Optional)
+Using the CLI, enter the command:
+  set-kcmd-cstate help
+Read over the ''help'' information, if you want to disable C-states, then...
+  set-kcmd-cstate disable
+!!Tip ->!! An added benefit to disabling C-states, it eliminates the high-pitched squeal at idle.
