 ==== Secure Boot
 
-If {productname} {this-version} has been installed on IBM z16 or later on an ECKD DASD as boot disk, the configuration parameter `SECURE_BOOT` in `/etc/sysconfig/bootloader` is automatically set to `no`, although the used hardware supports Secure Boot from ECKD DASD.
+If {productname} {this-version} has been installed, the configuration parameter `SECURE_BOOT` in `/etc/sysconfig/bootloader` is automatically set to `yes`.
 
-To enable Secure Boot support in this case, change the value for `SECURE_BOOT` in `/etc/sysconfig/bootloader` from `no` to `yes` and run `grub2-zipl-setup`.
+Please be aware that a combination of ECKD-DASD disk and Linux One III won't support Secure Boot.
