## How to Upgrade the System BIOS and ILOM Firmware

Note - In the instructions that follow, example dialog screen shots have been provided as a reference. Information displayed in each dialog may differ depending on your server model.

1. You should have already started SIA and prepared it for tasks as described in Starting SIA and Preparing for Deployment or Recovery Tasks and the Task Selection dialog should be displayed.
2. Select the System BIOS and ILOM Upgrade task, and then click Next.

   If your server supports inband upgrades (using the server's internal circuitry and not the network), the task list will show two options for System BIOS and ILOM upgrades: inband and network.

   Figure Legend
   1 | Example task list choices if your server supports network only upgrades.
   2 | Example task list choices if your server supports both inband and network upgrades.

   Note - An inband upgrade can take up to 40 minutes to complete and is only recommended if your server's service processor is not connected, or not reachable over the network.

3. If you are using the network method to perform the upgrade, enter the login information to your server's Service Processor and click Next.

   Note - The server must be able to access its management port over the network.

4. SIA compares the system BIOS and ILOM versions on the server against the available BIOS and ILOM versions in SIA.

   Note - If you performed an SIA Update during the current SIA session (described in How to Start SIA and Prepare for Tasks Using Local or Remote Media), the latest BIOS and ILOM versions for your server will have been obtained from the Oracle software download site.

5. If there is a later version of code available, click Next to begin the upgrade.

   Follow the on-screen instructions until the upgrade has completed. Upgraded code will not be used by the system until after a reboot.
