Step 2) Run SAA to get the BIOS config file.

Example

# ./saa -i 192.168.1.121 -u ADMIN -p ADMIN -c GetCurrentBiosCfg --file x13ddw_default.xml

Step 3) Make a copy of the Bios config file.

cp x13ddw_default.xml x13ddw_sb-enabled.xml

Step 4) Edit x13ddw_sb-enabled.xml and change these three settings, save and exit the file

Default:

<Setting name="CSM Support" selectedOption="Enabled" type="Option">   

<Setting name="SecureBootEnable" checkedStatus="Unchecked" type="CheckBox">  

<Setting name="ResetKeys" selectedOption="Disabled" type="Option">

SB enabled:

<Setting name="CSM Support" selectedOption="Disabled" type="Option">   

<Setting name="SecureBootEnable" checkedStatus="Checked" type="CheckBox">  

<Setting name="ResetKeys" selectedOption="Reset all keys to default" type="Option">

Run the SAA command to update the new BIOS config file and reboot the system in one command

# ./saa -i 192.168.1.121 -u ADMIN -p ADMIN -c ChangeBiosCfg --file x13ddw_sb-enabled.xml --reboot
