Imaging Computers at CF's and Institutions with Nov21:
You will need a docking station with USB ports and a reset USB. The most up to date reset USBs are labeled Nov21.
If necessary, image a device:
If necessary, backup student home folder to a USB drive before imaging computers
Dock the laptop (powered off) with a reset USB plugged into the docking station
Boot the computer, at the American Megatrends BIOS screen press Fn + F12 key repeatedly. You should be asked to enter a password. Enter the BIOS password.
Boot to the UEFI USB Drive. After that the process is pretty automatic but takes between two and five hours to finish.
Running the First Setup Script to finalize the new image:
The Red Wi-Fi Docking Station is optional here, but it will help to ensure that you have entered the correct Wi-Fi credentials. Additionally you will need the following information for the setup process: the student name and JRA number, the new jadmin password, the current time and date, and the Wi-Fi SSID and Password for the network that students are approved to access.
Log in as the jadmin account.
Open the Terminal Application by clicking the terminal button on the desktop or even taskbar at the bottom of the screen.
Type in: sudo bash first_setup.sh and press enter or you can simply press the up arrow key which will type the line for you then hit enter.
Follow the on screen text prompts entering the information you collected before starting the first setup script.
After finishing the script (the last step should have been entering the wifi password), reboot the securebook.
Fixing and/or Updating Wi-Fi Credentials:
The Red Wi-Fi Docking Station is optional here, but it will help to ensure that you have entered the correct Wi-Fi credentials.
Log in as jadmin.
Open the Terminal Application by Selecting the Terminal icon on the desktop or even the taskbar at the bottom of the screen.
Type in the following command: cd /etc/network
Now type in another command: sudo nano wifi-creds
Now edit the wifi credentials as you see fit. The first part is the SSID and the second is the Password. This are in clear text as you edit them so be careful who can see your screen.
When you have finished, hold down the CTRL key and press X.
Now it wants to know if you would like to save, press Y
It wants to know if you want to change the file name, but for the wifi to work the file needs to keep the same name so just press ENTER.
Close the terminal and reboot the Securebook, your wifi creds should now be fixed and up-to-date!
