Using the BIOS Setup Utility

You use the BIOS setup utility to modify BIOS settings and control system hardware.

To start the utility, as the system starts to boot and the Stratus ztC Endurance screen appears, press either the Delete key or the Esc key until the BIOS setup utility appears.

Notice: Do not change any BIOS settings from their default settings without first being asked to do so by Stratus Customer Service. The only exception is that if you want the Secure Boot setting enabled on a new system, you must explicitly enable it on both compute modules, and you do not need to be asked to do so by Stratus Customer Service. See Enable Secure Boot Setting in the BIOS Setup Utility for details.

Important Considerations When Using the BIOS Setup Utility

Consider the following important issues when you use the BIOS setup utility:

  • While you are making changes to the BIOS, make sure that only one compute module is running; the other compute module must be powered down. The safest way to do this is to power on one compute module at a time. See Shutting Down and Restarting a Compute Module.

  • Stratus software does change some BIOS settings from their default values, but only at specific times. For example, Stratus software enables the OS Watchdog Timer after the software installation is complete.
