IC-OS UEFI Configuration — Gen-2 Supermicro

BIOS and UEFI settings for Gen-2 Supermicro node machines — advanced ACPI, CPU, NB, xGMI, memory, PCIe, and Trusted Computing settings required by IC-OS.

·May 4, 2026·4 min read

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) — 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.

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 and follow the included update instructions before continuing.
