Automatically Update Firmware

By default, installing a BIOS or firmware RPM does not apply the update to the hardware. The update is manually applied using the update_firmware command. However, you can automatically update the hardware during RPM installation by configuring the /etc/firmware/firmware.conf file.

To automatically install BIOS and firmware updates, ensure that rpm_mode is set to auto in the firmware.conf file as shown:


# Automatically install BIOS updates when an RPM BIOS Update file is installed
# values: 'auto', 'manual'
# default: 'manual'
