6 System administration To maintain your thin client device environment, you can perform local and remote system administration tasks. The tasks include: • Accessing thin client BIOS settings • Unified Extensible Firmware Interface (UEFI) and secure boot • Using Wyse Management Suite • Ports and slots • Using Tight VNC (Sever and Viewer) to shadow a thin client Accessing thin client BIOS settings To access the thin client BIOS settings, do the following: 1 During system start-up, press F2 when you see a Dell logo. The BIOS Setup screen is displayed. 2 Change the BIOS settings as required. 3 Save the changes and exit. Unified Extensible Firmware Interface and secure boot Unified Extensible Firmware Interface (UEFI) is a standard firmware interface designed to improve software interoperability and address limitations of BIOS. UEFI is designed to replace Basic Input Output System (BIOS). Secure Boot is a feature on UEFI-based clients that help increase the security of a client by preventing unauthorized software from running on a client during the boot sequence. It checks whether each software has a valid signature, including the operating system (OS) that is loaded during booting. The thin client device is enabled with UEFI and Secure Boot. Due to this feature, you cannot boot from USB keys if you do not enter the BIOS, disable Secure Boot, change the boot mode to Legacy, and enable the Boot from USB option.
