Updating or recovering the BIOS This topic provides instructions on how to update the BIOS and how to recover from a POST and BIOS update failure. System programs are the basic layer of software built into your server. System programs include the POST, the UEFI BIOS, the Setup Utility program, and the TSM firmware. The POST is a set of tests and procedures that are performed each time you turn on your server. The UEFI BIOS is a layer of software that translates instructions from other layers of software into electrical signals that the server hardware can execute. You can use the Setup Utility program to view or change the configuration settings of your server. See "Using the Setup Utility program" on page 55. The TSM firmware provides remote management features. Lenovo might make changes and enhancements to the BIOS and TSM firmware. When updates are released, they are available for download on the Lenovo Web site at http://www.lenovo.com/drivers. You can update the server firmware by downloading an update package and following the instructions on the Web page. Updating (flashing) the BIOS This topic provides instructions on how to update (flash) the BIOS. Notes: • Update the BIOS on your server only if the newer BIOS version specifically solves a problem you have. We do not recommend BIOS updates for servers that do not need them. You can view the updated information for the new BIOS version in the installation instructions for the BIOS update utility program. • Downgrading the BIOS to an earlier version is not recommended and might not be supported. An earlier BIOS version might not support the latest system configurations. • If the power to your server is interrupted while the POST and BIOS are being updated, your server might not restart correctly. Ensure that you perform the BIOS update procedure in an environment with a steady power supply. Besides, ensure that your server can restart successfully without encountering hardware problems. • If you have updated the BIOS firmware, all the BIOS settings become the default settings of the updated BIOS version. Check and reconfigure the BIOS settings for your specific needs. You can record your specific BIOS settings before updating the BIOS for an easier reconfiguration in the new BIOS version. To update (flash) the BIOS, do the following: 1. Go to http://www.lenovo.com/drivers and follow the instructions on the Web page to locate the BIOS update package. 2. Download the BIOS update package and the installation instructions in a TXT file. 3. Print the TXT file that contains the installation instructions and follow the instructions to update (flash) the BIOS. 4. Check and reconfigure the BIOS settings for your specific needs based on your note or refer to "Using the Setup Utility program" on page 55 after the BIOS update process is completed. Recovering from a BIOS update failure If the power to your server is interrupted while the BIOS is being updated, your server might not restart correctly. Perform the following procedure to recover from the BIOS update failure. Note: If the operating system of your server is installed under EFI mode, reinstall the operating system after recovering the BIOS. To recover from a BIOS update failure, do one of the following: • Using the automatic recovery feature Chapter 5. Configuring the server 61
