-## Set up an alternative firmware path for the cluster 
-The command below sets `/var/lib/firmware` as the alternative firmware path since the default firmware path `/lib/firmware` is read-only on RHCOS.

-$ oc apply -f https://raw.githubusercontent.com/intel/intel-technology-enabling-for-openshift/main/machine_configuration/100-alternative-fw-path-for-worker-nodes.yaml

-**Note**: This command reboots all the worker nodes sequentially. To avoid reboot on Day 2, the cluster administrator can perform this step on Day 1.

-## Verification
-### From the web console
-Navigate to the Compute -> MachineConfigPools section to check the status and make sure the MachineConfigPool update is complete. The status will update from `Updating` to `Up to date`.
