This runbook configures the BIOS/UEFI on a **Gen-2 Supermicro** server
so that IC-OS can install and run correctly. It is the BIOS-side step
of the [Node Deployment Guide (Gen-2)](/wiki/node-deployment-gen-2/) —
at section 9, "UEFI setup and boot menu", branch here, complete the
steps below, then return to the deployment guide and continue to step
10.

> [!WARNING]
> Do **not** enable the RAID BIOS setting. RAID will break IC-OS
> installation.

## 1. UEFI — Enter Setup

1. Reboot or power on the server.
2. Watch for the screen with the Supermicro logo and boot options
   listed underneath.
3. Press **DEL** (delete) a couple of times once the options are
   listed.

## 2. UEFI — Check version

Check the version number at the bottom of the screen. The UEFI/BIOS
version must be **2.21.1280** or higher — this is the version tested
to support the features IC-OS requires.

If the version is lower than **2.21.1280**, download the latest version
from the [Supermicro support site](https://www.supermicro.com/en/support/resources/downloadcenter/swdownload)
